I’m building a reusable Blazor WebAssembly SPA template for business projects and need a seasoned .NET 8 developer to turn my specification into a clean, pluggable starter kit. What I need built: • HTML/CSS Template layout for Blazor – header, left/right panels, main body and footer, wired for light / dark switching. Only sample placeholder content is necessary so the focus stays on the template and left/right and scrollable mechanics. • Static values replaced by tokens – every colour, font or spacing value must be expressed as a placeholder such as «HeavyValidationAccent». A single JSON file will hold the real values so that swapping themes is a simple file change. • Demo application – at dev or run-time the app should read the JSON, rep...

I’m ready to build a Windows-compatible application that lets me drop in raw Propwire or Propstream exports (currently CSV only) and receive a clean, research-ready dataset. Once imported, the data should automatically sort by Zip code while still keeping key fields—parcel number, owner name, current deed, encumbrances, length of ownership, property-tax status, and any municipal code violations—readily filterable. The core of the job is an algorithm that applies my own grading rules and assigns every record a numbered score. When I open a property profile I want a “deep dive” view that compiles all of the above details plus up-to-date contact information for the current owner in one place. Deliverables I need to see: • Import module that accepts P...

Every afternoon I log dozens of order updates and I need a small Windows desktop program that lets me do it quickly and without distractions. The core requirement is a clean data-entry form: fields for order number, customer name, current status, date/time (auto-stamped is fine), and an open notes box. Once the record is saved it should be written to a lightweight local store—SQLite or a simple embedded database is perfect—so I can review or export the data later. I do not need reporting dashboards or sign-in screens at this stage; the entire focus is on fast, reliable entry. A single-window WinForms or WPF build in C#, Electron with a local store, or any comparable Windows-only framework works for me as long as it installs with minimal fuss. Acceptance criteria • Exec...

For my company Awizohub, I need a streamlined, web-based tool that lets me generate and print QR-code stickers in multiple label sizes without fussing over which printer I am using. From a single Google Chrome tab I want to: • Type or bulk-paste the data that the QR code should hold (CSV upload is fine). • Pick a predefined label template or quickly enter custom width, height, gap, and margin. • Preview the sheet/roll so I can confirm alignment before wasting labels. • Hit “Print” and have the app push a perfect layout to any connected printer—desktop laser, ink-jet, or thermal label printer—leveraging the browser’s print dialog or a PDF download. Accuracy is critical: the printed code must stay within tolerance so every scanner rea...

I have an existing C#/.NET automated trading application (V131) using the FXCM ForexConnect API. The application and trading strategy are already developed. I am NOT looking to rebuild or redesign the trading strategy. I need an experienced C#/.NET developer to complete and troubleshoot the existing FXCM ForexConnect integration, particularly connection, live order execution and order/position management. Experience with FXCM ForexConnect is strongly preferred. The developer will work from the existing V131 source code. Please indicate your specific experience with FXCM ForexConnect or similar broker APIs.

I still have a working copy of our old “export” utility--a small .NET Windows Forms program that pulls voice recordings from our recorder software through its SDK--but the original source code is gone. I need someone who can decompile that executable, clean up the recovered code, and then refactor the tool so it runs purely from the Windows command prompt. Instead of the current dialog box, the new build must accept: • a start time and end time parameter that define the export window • a list of one or more phone extensions to filter the recordings Everything else about the workflow stays the same: the program will talk to the recorder SDK, fetch the selected recordings, and drop the files into a local folder on the same server where the recorder software already ...

I need Microsoft RMS Store Operations to hand transactions seamlessly to VIPay and route them to our Ingenico Lane 3000 terminals. The scope is narrow and clear: real-time transaction processing only—no inventory sync or back-office reporting. The integration must: • Launch from the standard RMS tender screen and pass sale totals to VIPay • Drive the Lane 3000 for EMV chip, mag-stripe and contactless payments • Return an approved/declined response to RMS and post it to the receipt journal Supported transaction types are credit and debit, and we must clear Visa/MasterCard, American Express and Discover through VIPay’s gateway. Please build whichever RMS add-in or external helper service you prefer, so long as it installs cleanly on our .NET RMS environm...

We are looking for a Senior .NET / Distributed Systems Developer to work on an existing ASP.NET Web Forms + C# + SQL Server based Biometric Attendance & HRMS application. Currently, biometric device communication and HRMS business processing run in the same application/server environment. During high biometric device traffic, the device communication consumes excessive CPU, RAM, database connections and application resources, which can affect or shut down the complete HRMS application. We need to separate the biometric device communication layer from the HRMS application and build an independently scalable architecture. Target architecture: Independent Biometric Device Gateway Persistent TCP/IP device connections Multiple Gateway servers with load balancing Kafka or RabbitMQ messag...

I am assembling a live, online training program for a group of beginner-level engineers who must quickly come up to speed on AVEVA’s plant design ecosystem. The curriculum is already sketched out—Common Foundation → AVEVA Foundation → Role-based Specialization → Supporting Tools → Domain Enablement → Project/Capstone → Assessment—but I want a seasoned trainer or SME to take full ownership of the Software Tool Training track. The three core modules you will teach are: • AVEVA E3D / PDMS • AVEVA P&ID / NextGen P&ID • AVEVA Unified Engineering Because the cohort is starting from zero, every concept needs to be demonstrated hands-on, with plenty of practical examples that tie back to EPC and plant-engineering workfl...
