I need a skilled data scientist to perform thorough descriptive analysis on an existing dataset. The goal is to surface key trends, summary statistics, and clear visual insights that non-technical stakeholders can quickly grasp. I will supply the raw data once we agree on the engagement; it is already cleaned enough for immediate exploration, but I’m open to your recommendations if additional preprocessing will strengthen the final story the numbers tell. Typical tools such as Python (pandas, matplotlib, seaborn), R (dplyr, ggplot2), or even Power BI/Tableau are all acceptable—please work in whichever environment lets you deliver crisp, reproducible results fastest. Deliverables • Concise written report (PDF or Word) outlining findings, notable patterns, and any unexpec...

I have several datasets that need to be transformed into clean, well-structured information. At this stage I’m still defining the exact scope, so I’m open to a range of data-writing approaches—whether that involves straightforward data entry from spreadsheets, deeper analytical summaries drawn from a database, or shaping web-scraped records into a narrative that can power a report, a machine-learning pipeline, or an interactive dashboard. Here’s what I need from you: • A brief outline of how you would tackle the job once you see the raw files. • Your preferred tools—Excel, SQL, Python (Pandas, NumPy), or any other stack you’re comfortable with. • A sample of comparable work, if available, so I can gauge fit and style. • An es...

Key Requirements: - Regional scale (state or province) - PDF format - Highlight watershed boundaries Ideal Skills: - Proficiency in GIS software - Experience in creating printable maps - Attention to detail in map design

I have a collection of raw information that needs to be turned into clean, well-structured data. Your task is to take what I provide, enter it accurately, check for consistency, and present it in a clearly formatted file we agree on before you start—whether that ends up being Excel, CSV, or Word. Attention to detail and solid keyboard speed matter more to me than fancy tools, but if you prefer working with spreadsheets, text-processing macros, or simple scripts to accelerate the workflow, feel free to use them. What I really care about is a final file that is error-free, neatly organised, and easy for me to sort or filter later. Send a brief note describing the approach you’d take to keep the data clean from the first keystroke through final delivery, along with a realistic t...

I need two tightly-connected newsroom tools built as installable modules that can drop into a modern CMS (WordPress, Joomla, or Drupal—whichever you feel most confident customising). 1) Editorial Calendar & Planning The calendar must let editors line-up stories by date, assign them to reporters, and keep everyone talking in one place. At minimum it has to cover: • Content scheduling with a clear visual timeline • Task assignment that tracks status from pitch to publish • Lightweight collaboration/chat inside each story card 2) Reporter KPI Scoring Each published piece should automatically flow into a scoring engine that credits the reporter on: • Article reach • Publishing frequency • Reader engagement On top of those raw count...

Excel report cleanup + dashboard (financial tracking) have an Excel report that tracks project funding, spend, and monthly invoices. The data is fine, but the layout is messy and hard to follow. Looking for someone to clean it up and make it easier to read, especially for leadership. Main things I need: A simple summary at the top (total funding, spent, remaining, runout date) Cleaner layout for the monthly invoice tracking A couple of basic charts to show burn and trends Overall structure that’s easy to maintain month to month Not looking for anything over the top. Just clean, clear, and professional. This will stay in Excel. If you’ve done similar work, send a sample. End goal is something I can send up without having to explain it every time.

I need a Python-based tool that takes a list of recent textbook ISBNs (last 3 years), pulls real sold prices from eBay, and compares them to current buy prices on AddALL, BookFinder, and Amazon (optionally AbeBooks/ThriftBooks). The tool should calculate fees, estimated shipping, net profit, and ROI, then export everything to CSV/Excel with a clear BUY/SKIP recommendation for each ISBN. Please quote for a stable Version 1 that I can run regularly, plus what you’d charge for future small improvements.

I have a batch of essays in PDF format and I need a clear, apples-to-apples comparison of their sentence lengths. Your task is to extract the text from each file, determine the length of every sentence, and then show me how the essays stack up against one another. What matters most is the comparative insight: average sentence length, shortest and longest sentences, and any notable patterns that emerge when the papers are placed side by side. A concise write-up or visual (a small chart is fine) that highlights these differences will round out the job. You may work with whatever parsing approach you prefer—Python with PyPDF2, spaCy or NLTK are perfectly acceptable—but the final output should include: • A spreadsheet (or CSV) listing each essay, total sentences, avera...

I have a complete dump of our sales data and need it translated into clear, actionable insight on customer preferences. The sole focus is understanding customer behavior, not broad market trends, so every cut of the data should point back to what drives people to choose one product, bundle, price point, or channel over another. The raw files can be delivered in whichever structure you prefer—CSV, SQL, or a direct BI connection—and I am open to Python, R, Power BI, Tableau, or a combination that will surface patterns quickly. The end goal is to know, with evidence, which product attributes and buying contexts most influence a purchase so that future campaigns and merchandising decisions can be laser-focused. Deliverables • A cleaned, well-documented dataset ready for re...

I need my full thesis distilled into a polished, professional-looking PowerPoint that follows the template I will supply. Every section of the final report must appear—introduction, background, methodology, results, discussion, conclusions and recommendations—yet the slides should stay concise, visually balanced and easy to follow. The template already sets the core colours and fonts, so your job is to weave creative, clear visual material (charts, icons, well-chosen images) into that framework without breaking its style rules. Please add detailed speaker notes beneath each slide; they should be thorough enough that someone could present confidently just by reading them. Key deliverables • Full editable .pptx file matching my template • All thesis content tr...

I have a collection of historic “Bombay Presidency” cadastral tippans that include their original base-line measurements and a series of handwritten offsets. I want to transfer these sheets into a clean, georeferenced layer inside QGIS through a custom plugin rather than drawing every feature by hand. What the tool must do • Offer fully customizable digitization tools: while tracing a baseline, the plugin should let me enter each offset (distance and side) and automatically draw the resulting parcel edges. • Work in a single, fixed coordinate system that I will supply at the start of the project—no need for on-the-fly reprojection. • Export the finished geometry to a Shapefile with all entered attributes preserved. Deliverables • Compiled Q...

I need an interactive Power BI dashboard that lets our team grasp operational efficiency at a glance. The emphasis is less on cramming in every possible visual and more on presenting the information so anyone—from frontline supervisors to executives—can instantly read, filter, and understand it. My core goal is clear, intuitive report display and understanding. Once the model is in place I should be able to slice results by date, team, and location without waiting for new queries or edits. You’re free to recommend the visual types that best communicate the story; the key requirement is that they remain consistent, on-brand, and easy to interpret. I will supply the raw operational data in Excel and CSV. If calculated columns, DAX measures, or a star-schema redesign will ...

I need a clear, data-driven report that lets me monitor how satisfied end users are with our IT help desk. The ticketing system already stores all the raw data; what I’m missing is a concise view that translates that data into actionable insights. The report must zero in on three satisfaction drivers: • Response time • Resolution quality • Agent professionalism I’m happy for you to work in the environment you’re most comfortable with—Excel, Power BI, Tableau or a direct SQL‐based dashboard are all acceptable—so long as the final output is easy for non-technical managers to read and refresh on demand. Trend charts, scorecards, and a short narrative summary will help leadership see at a glance where we’re excelling and where we n...

I have a numerical dataset that needs a careful scrub before any sense can be made of it. The main headache right now is outliers—they are skewing the story the numbers are trying to tell. I need you to detect, diagnose, and treat those extreme values using an approach you can justify statistically (Python / Pandas, R, or even advanced Excel are all fine as long as the method is transparent and reproducible). Once the data are healthy, I want straightforward descriptive statistics—think clear measures of central tendency, dispersion, and a concise written interpretation that highlights anything interesting the cleaned data reveals. No forecasting or trend-spotting models this time; just an honest summary of what the numbers say after the noise is removed. Deliverables: •...

I have a collection of scientific articles in text form and I want a clear, reproducible way to uncover the key themes and topics running through them. The core of the task is natural-language processing: ingest the articles, clean and normalize the text, then apply topic-modeling or similar techniques to surface the dominant concepts. My preference is a Python-based workflow—think spaCy, NLTK, gensim, BERTopic, or comparable libraries—but I’m open to whatever stack you feel will give the most coherent results. Visual summaries such as word clouds or interactive topic maps are definitely welcome if they help make the findings intuitive. Deliverables • Well-commented code or notebook that I can run locally without tweaks • A short methodological write-up ...

I have a well-structured sales dataset that now needs to be translated into clear, insightful reports. The main deliverable is an Excel file that not only presents the raw numbers neatly, but also highlights key findings through pivot tables, charts, and concise commentary so any stakeholder can grasp performance at a glance. You’ll have full access to the dataset as soon as we start. I’m expecting you to clean and validate the data where needed, surface relevant metrics such as revenue by product, region, and period, and expose any seasonality or growth patterns you uncover. Please let your analysis drive the story—if a particular segment or trend stands out, bring it forward in the workbook. Acceptance criteria • One well-organized Excel workbook containing: ...

I have raw customer-focused data coming in from several marketing platforms (think Meta Ads, Google Ads, and similar). I need that information cleaned, modelled, and turned into an interactive Excel dashboard that lets me monitor customer acquisition in near-real time. Here is what I’m looking for you to deliver: • A well-structured Excel file that imports the marketing-platform exports, applies repeatable cleaning steps, and stores the tidy tables on separate, clearly named sheets. • Dynamic calculations that surface the key acquisition metrics we care about (cost per lead, cost per customer, conversion rate, and any other ratios you typically track for this goal). • An intuitive dashboard tab: slicers, drop-downs, and visually appealing charts so I can filte...

I need a concise script or repeatable workflow that scans a batch of academic papers (PDF, DOCX, or plain-text) and reports how often sentences fall into two buckets: short sentences containing fewer than 10 words and long sentences containing more than 20 words. Everything in between can be ignored or grouped as “mid-range”—the focus is squarely on the extremes. Here is what I expect: • Input: a folder of research articles that may vary in format. • Processing: automatic extraction of the body text and measurement of every sentence’s word count. • Output: a clear summary—per document and aggregated—showing counts and percentages of short vs. long sentences, plus optional CSV and simple visualisations (bar chart or histogram) to ma...

I already have a working MATLAB model that generates particles, defines the micro-channel geometry, and steps the simulation forward, but the trajectories are drifting away from the intended channel centrelines. Your task is to bring those paths back into proper alignment with the device. What I need • Correct the alignment of particle trajectories by adjusting the entry points and modifying particle flow direction within the code. • Tackle the root cause: the current channel geometry parameters are influencing the solver in a way that deflects particles, so the fix must happen where those geometric terms are fed into the velocity field or boundary conditions. • Return a clean, well-commented .m file (or set of functions) that reproduces the corrected behaviour, plus ...

I’ve built our social-media content calendar in Excel and now need a clear, scroll-friendly timeline inside the same file. The goal is to glance at the sheet and instantly see which posts are scheduled, which channel or format they belong to, and how they line up across the coming days. Here is what I need you to deliver: • Insert an in-sheet timeline (think lightweight Gantt) that automatically pulls from the existing rows. • Display two data points on every bar: the scheduled post date and its content type (e.g., Reel, Story, Blog-link). • Keep it dynamic—when we add or shift a row, the visual updates without extra steps. The workbook is already structured; you can add helper columns, named ranges, or PivotCharts if that speeds things up, but please a...

I need an instructor who can run an intensive Dynatrace boot-camp for an advanced audience. The program will run over five consecutive days, 2–3 hours each session, and must stay highly practical: every concept you show should be demonstrated live, from console walk-throughs to real data flowing in.
