About me

I build websites, web applications, Python automations and AI-assisted tools that solve a specific business problem.

I have 20+ years of software engineering experience, from financial and embedded systems to backend development, cloud platforms and AI. My background includes FlyrLabs and projects for Nokia, Credit Suisse and GSK.

I can help you build or improve: • a business website, landing page or CMS-based service; • a web application, API or system integration; • workflows for documents, files and structured data; • an AI pilot: RAG search, OCR or a human-reviewed assistant.

My stack includes Python/FastAPI, React/TypeScript, WordPress, PostgreSQL and Docker. My portfolio distinguishes public websites from local MVPs and technical prototypes.

I start with your goal, scope and acceptance criteria, then propose a practical first milestone. Tell me what you want to improve.
