A landing page for a specialty coffee shop with a live menu showcase and location details. Small brief, obsessive execution, the kind of page you scroll twice.

I'm Jakub, a full-stack developer who treats the last pixel and the last query with equal respect.
I design and build complete web and mobile products: database architecture and APIs, business logic, and interfaces that are a pleasure to use. Mostly SaaS platforms and custom B2B systems.
I like taking full ownership: from the first commit to production deployment. Performance, scalability and maintainable code are part of the job, not an afterthought.
How I work
Own it end to end
A product is done when it runs in production, not when the PR merges.
Performance is a feature
Speed is user experience you can measure. I budget for it from day one.
Boring tech, exciting products
Proven tools, ambitious outcomes. The stack should never be the risk.
Details build trust
Alignment, empty states, error copy: the last 5% is the product people feel.
Frontend(4)
// client & mobile
Backend(6)
// services & APIs
Data(4)
// where state lives
Tooling(7)
// ship & observe
Tools serve the problem, never the other way around. The stack above is what ships products today, not a wishlist.
Specialty coffee shop: live menu showcase and location details. Small scope, high polish.
Construction company: architectural projects, custom builds and client services.
Custom B2B systems, client work, and a few hundred commits of learning what not to repeat.
