About this gig

I build web apps and MVPs in Python or TypeScript: from an internal dashboard to a first version of your product with login, a database and the core features you need to test your idea.

Recent work: a production service that generates structured data for Shopify and WooCommerce stores (TypeScript, PostgreSQL, React admin), and a trend monitoring platform with a React dashboard, running in production with Docker.

How I work:

  • you choose the features, and before I start we agree on what each one does
  • you see a working version early
  • delivery includes the code, tests and handover documentation, and in Premium also putting it online on a hosting account of your own (hosting costs are yours)

Send me a short description of your idea before ordering, so I can confirm the scope and which package fits.

I build web apps, scrapers and AI tools that businesses actually use. Recent work: an app that checks student files for completeness with a local LLM, a service that generates structured data for Shopify and WooCommerce stores, and a scraping pipeline that tracks around 1,500 products a day. I work in Python, TypeScript and SQL, and every delivery comes with tests and a short explanation of how to run it. MSc student in Data Science, with bachelor's degrees in AI and Business Administration.
