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.

Portfolio
Public class website with registration and member materials. React/TypeScript and a custom WordPress plugin for video access and email/SMS queues. Development and integrations on a Lovable frontend base.
CLI MVP: JSON scenario to Playwright recording, Azure Speech narration, captions and FFmpeg assembly. Manifests, execution-based timeline, resumable stages and Kdenlive export. TypeScript/Node.js; not a SaaS platform.
Private technical PoC for controlled document acquisition: Gmail/Drive, OAuth, operation-specific approval, hashes and audit. Python/Azure. Separates originals from derived outputs; not a finished legal system.
WordPress website for a service business: service pages, practitioner profile, reviews, blog and a clear path to contact and Booksy bookings. Public website project; Booksy is an external service.
Own technology brand website: services, products, portfolio and PL/EN content. React/TypeScript, development from a Lovable base, technical SEO and static deployment. Clearly distinguishes products from prototypes.
