We specialize in projects where multiple technologies must work together seamlessly — software with hardware, cloud with automation, and logic with real-world operational constraints. Our work is driven by solid architecture, clean implementation, and solutions designed for long-term use, stability, and growth. 🔧 Core Capabilities Systems & Full-Stack Development End-to-end design and development of web platforms, backend services, APIs, dashboards, and mobile applications, built for scalability, security, and maintainability. Cloud, DevOps & Infrastructure Architecture and operations across AWS, Azure, and Google Cloud, including CI/CD pipelines, deployments, monitoring, performance optimization, and production hardening. Automation & Integrations Custom automation, workflow optimization, system integrations, bots, and backend processes to reduce manual work and improve operational reliability. Embedded Systems & Industrial Automation Development and integration of embedded systems, IoT devices, electronics, PCBs, PLCs, SCADA, and hardware–software interfaces for industrial and automation use cases. AI & Data-Driven Features Practical AI and machine-learning integrations such as computer vision, OCR, analytics, and intelligent system enhancements — applied where they deliver real, measurable value. Specialized & Custom Solutions Blockchain systems, trading tools, telephony platforms, and other domain-specific solutions when projects require deeper technical customization. 👥 Team & Delivery Model For larger or time-critical projects, I work with a small, trusted technical team, while personally managing and reviewing all work. This ensures clear communication, consistent quality, and a single point of accountability for the client. 🤝 Post-Delivery Support Delivery does not end at handover. We provide clear documentation, support, fixes, and ongoing assistance when required, ensuring systems remain stable, understandable, and easy to maintain over time. Our approach is reflected in consistent positive feedback from previous clients, who value technical ownership, clear communication, and dependable delivery. If you’re looking for a technical partner who thinks long-term and takes responsibility beyond launch, Rashid Tech Solutions is ready to support your project. λιγότερα

I’m a full stack developer with over 10 years of experience building all kinds of digital products—from websites and mobile apps to blockchain platforms, embedded systems, and AI-powered solutions. I’ve worn a lot of hats over the years, but the common thread has always been solving real problems with smart, reliable tech. Whether you’re looking to launch something new or need help improving what you’ve already built, I’m here to jump in and make it work. -Web & Mobile Apps: Clean, responsive designs and solid backend logic. I work with tools like React, Vue, Node.js, Django, Flutter, and more to build apps people actually enjoy using. -Embedded Systems & IoT: I build smart, connected hardware using platforms like Arduino, ESP32, and Raspberry Pi. From prototyping to production-ready firmware, I work with C/C++, MicroPython, and platform-specific SDKs to control sensors, motors, displays, and more. I also integrate these systems with web and cloud services—often adding AI for tasks like real-time data analysis, voice interaction, or image recognition at the edge. -AI & Machine Learning: I integrate tools like GPT-4, Whisper (speech-to-text), and DALL·E into web and mobile platforms—automating workflows, building chatbots, content generators, or even custom AI copilots for your users or team. I also work with Python-based ML frameworks like TensorFlow and PyTorch for custom models and training. -Blockchain & Smart Contracts: I’ve developed and audited smart contracts (mainly Solidity) and built dApps that connect seamlessly with Ethereum, Solana, and BNB networks. Let’s bring your vision to life with clean architecture, scalable code, and tech that lasts. I’m ready to contribute as your long-term tech partner or on-demand expert. λιγότερα
