About
I have more than 15 years of programming experience. As a freelancer, I have broad experience: I developed web (ASP.NET, Python, PHP), desktop (C++, C#, Python — Linux and Windows) and mobile (Android — Java, C++) applications.
I list here some of my jobs.
C#:
- clubspeed.com — a large software suite for family entertainment clubs; included C# code (80%), including CoreApi and ASP.NET Razor, plus PHP (Laravel) and Node.js code (for low-level car racing control tasks). I developed it as a team member.
- qadra.com — a financial company; C# code (80%), Python (some microservices are Python/Flask based, 20% of code), AWS-hosted with Docker containers and Lambdas. I developed it as a team member.
- enven.nl — implemented from scratch their non-public partners portal: ASP.NET Razor and some CoreApi endpoints.
- ASP.NET website for house rentals.
- ASP.NET website for remote control of a robotic device via a WebSocket connection.
- Vegetable-oil plant automation desktop program (C# + WinCC).
Python:
- Embeddable fact-checking chat that uses the LangGraph framework to implement a customizable LLM/AI backend (OpenAI, DeepSeek, Hugging Face, or Ollama). It allows administrators to embed the component in their websites so users can ask questions about facts described in articles and verify whether facts listed in an article are true. It included agentic code and many external APIs to check facts (not just asking an LLM), and even computer vision to inspect website photos (OpenCV). Backend is FastAPI.
- AI/LLM-based ad selection for a website (FastAPI and LangGraph). It processes website text or chat messages and selects ads of different types related to the content. It contains SDKs for embedding ads on many platforms, including Go, React, and plain HTML.
- Polish-language training software, based on Django and LangGraph.
- Many small projects: desktop scripts, web scraping (Selenium and related tools), and simple AI agents.
C++:
- Factory equipment monitoring system (Ubuntu Linux, custom server over TCP/IP, web interface in PHP).
- Many small projects, some of which are mentioned in reviews on this profile; many are non-public.
- Powerful software for automated ad submission on social networks (massive bots that send millions of messages).
