> whoami

Web developer from Warsaw. Backend-first - PHP, WordPress internals, custom integrations, server-side tracking. I build e-commerce stores, payment systems, and conversion tracking that works even when AdBlock is on.

By day I write custom WordPress themes, build WooCommerce stores, and integrate payment + tracking systems (Stripe, Klarna, Facebook CAPI). Design came alongside it - Figma, Photoshop, Blender. My projects go from an empty canvas to production deploy.

Projects span e-commerce, e-learning, education, real estate, medicine, luxury perfumes and wooden accessories.

🎬 Off-duty

INTP-T. Night owl. Gym regular (110 kg bench, calisthenics), ex-runner working on a comeback. Animation and anime fan - from Spider-Verse and Avatar: TLA to Death Note and BoJack Horseman. Big into superhero deconstruction (The Boys, Invincible). Emotional about The Notebook and Up (Pixar). Grew up on The Prestige, Pirates of the Caribbean, and way too many comics. Still rewatches Rick and Morty. Plays games, collects memes that are way too specific, and sometimes opens Blender just to see what happens.


📬 Contact

Available for freelance projects & open to new opportunities.

I work best on: WordPress internals & WooCommerce (custom plugins, hooks, integrations), tracking setups (Facebook CAPI, GTM, GA4, Stripe), web apps where backend logic matters - and messy codebases that need fixing or serious optimization.

If you have a real project and need someone who handles the full pipeline from design to deploy - let's talk.

Something new is coming - Nonstetic - stay tuned.

🎬 Po godzinach

INTP-T. Nocny marek. Siłownia (110 kg na ławce, kalistenika), ex-biegacz pracujący nad comebackiem. Fan animacji i anime - od Spider-Verse i Avatara: Legenda Aanga po Death Note i BoJacka Horsemana. Dekonstrukcja superbohaterów to mój gatunek (The Boys, Invincible). Wzruszam się na Pamiętniku i Odlocie (Pixar). Wyrosłem na Prestiżu, Piratach z Karaibów i za dużej ilości komiksów. Wciąż oglądam Ricka i Mortiego. Gram w gry, zbieram memy które są zbyt niszowe, i czasem otwieram Blendera żeby zobaczyć co się stanie.


📬 Kontakt

Dostępny na zlecenia freelance i otwarty na nowe możliwości współpracy.

Najlepiej pracuje mi się przy: WordPress internals & WooCommerce (custom pluginy, hooki, integracje), setupach trackingowych (Facebook CAPI, GTM, GA4, Stripe), aplikacjach webowych gdzie liczy się logika backendowa - i przy projektach które ktoś już zaczął i trzeba to ponaprawiać lub porządnie zoptymalizować.

Jeśli masz konkretny projekt i szukasz kogoś kto ogarnie cały pipeline od designu po deploy - napisz.

Coś nowego nadchodzi - Nonstetic - stay tuned.
