Hire the Best PyQt Developers

PhD-trained engineer building production AI applications with Python, Django, and modern LLM tooling. I take AI projects from prototype to shipped product — RAG systems, agents, custom integrations, and the full-stack web or desktop applications that wrap them. What I'm hired for: - LLM application engineering — RAG pipelines, multi-step agents, custom evaluation harnesses, OpenAI / Anthropic / open-source model integration, structured output and tool use, prompt and retrieval optimization - Django & FastAPI backends for AI products — auth, billing, async job queues, streaming responses, vector stores (pgvector, Qdrant, Chroma), observability for LLM calls - AI-powered desktop applications — Tauri (Rust) and PyQt5 for clients who need offline-capable, on-prem, or data-sensitive tools. A rare combination: most AI engineers can't ship desktop; most desktop developers can't ship AI - Scientific and R&D software — instrumentation control, data pipelines, numerical analysis. Background suited to biotech, hardware, and research-driven startups Background: - PhD in Electrical Engineering, University of Southampton (2022) - 2,300+ hours and $100K+ delivered on Upwork. Top Rated, 100% Job Success - Roles at two scientific instrumentation startups (Lightcast Discovery, CellCraft) Core stack: Python, Rust, Django, FastAPI, HTMX, PostgreSQL + pgvector, Docker, Kubernetes, AWS, OpenAI/Anthropic APIs, Tauri, PyQt5. I work best with founders and small teams who want someone senior — someone who'll push back on bad ideas, ship clean code, and stay with the project until it works in production, not just in a demo. If that sounds like what you need, send me a few sentences about what you're building and we'll talk.

I’m a Software Engineer with strong experience in Python, JavaScript, and full-stack web development, focused on building scalable, high-performance applications. I specialize in backend development with Flask, REST APIs, and MySQL, along with modern frontend solutions using HTML, CSS, and dynamic JavaScript interfaces. My work includes API development, database design, automation scripts, and system integration, as well as handling complex workflows such as audio processing, multimedia pipelines, DICOM processing, and data transformation. I’ve also worked with tools and libraries like PyQt / PySide and ffmpeg, giving me a versatile skill set across both web and desktop environments. I’m experienced in debugging, performance optimization, and clean architecture, ensuring that every solution is not only functional but also maintainable and efficient. I also leverage advanced AI-assisted development tools (including Claude Max) to accelerate delivery, improve code quality, and explore optimized solutions when tackling complex problems. Whether it's building a system from scratch, improving an existing codebase, or solving critical bugs, I focus on delivering reliable, production-ready results. If you’re looking for a developer skilled in Python, Flask, JavaScript, APIs, MySQL, automation, and scalable systems, I can help turn your ideas into solid, working software.

Profile Summary I am a PyQt and Full-Stack Developer with a strong background in Data Science and Machine Learning, specializing in building intelligent, end-to-end software solutions.

I'm a Polish developer with a genuine passion for building things that actually work — and work well. I specialize in Flutter mobile development, Python scripting & automation, and web development with Flask and FastAPI. My published Android app, ADHDaily, is a habit tracker designed specifically for people with ADHD — built from scratch, live on Google Play, and a project I'm genuinely proud of. I also built a full e-commerce website for a real business client during my internship, so I know what it means to deliver something production-ready. What you can expect working with me: — I can focus for long hours on a single problem until it's solved properly — I'm detail-oriented and don't cut corners — I'm open to feedback and enjoy discussing ideas — communication is never an issue — I work independently and don't need hand-holding Outside of client work I build my own automations and dabble in game development, so I'm always learning something new. If you need a developer who takes your project seriously — let's talk.
