Capability
Backend & APIs
The engine room — typed services, clean data models, and REST/GraphQL APIs built to scale. We design backends you can reason about, test, and grow without nasty surprises.
Proof, not promises
Backend & APIs we've shipped
Modernized a 20-year-old C# monolith powering most US health universities — incrementally, no big-bang rewrite.
A modern tournament-management SaaS — registration, automated brackets, live scores — across web, iOS and Android from one codebase.
Built an international tours marketplace + operator SaaS from scratch, and advised the founders through fundraising.
A Polish social job aggregator — 'LinkedIn before LinkedIn' — tuned for ~40M monthly page views.
A super-interactive online radio: live chat, song requests, profiles and ranks, realtime over WebSockets.
Moved specialist dictionary publishing online — public portal, reseller panel, and a browser-based editor — built from scratch.
