About
I work end-to-end: from requirements analysis and architecture through delivery and maintenance. In commercial projects I focus on clear code, reliable integrations, and solutions aligned with real business needs rather than technology trends.
In my own time I build tools and prototypes, mainly in the React ecosystem, which helps me validate ideas faster and bring proven patterns back into team work.

Collaboration
I help deliver web applications, internal tools, and product prototypes. I am happy to discuss scope, timeline, and pricing.
