About me

Chętnie podejmę się zleceń dotyczących budowy, modyfikacji i utrzymania aplikacji webowych, stron i sklepów internetowych. Moja specjalizacja to backend, ale jestem w stanie pracować również przy froncie (React.js, JS / jQuery). Mam 8-letnie doświadczenie komercyjne, zaczynając od drobnej agencji kreatywnej, poprzez freelancing, aplikacje contentowe w startupach i pracę przy mikroserwisach w wielotysięcznej korporacji.
