Act 01 · The method
I work step-by-step with AI on a workflow I've refined over years. Not the copy-paste vibe-code that produces buggy demos. Every architectural choice, every shader, every CSS variable is intentional and mine.
That's why I ship the same scope and quality an agency would, faster, and at a price a solo operator can charge.

Tell me your idea→Act 05 · Who you hire
Real name Patryk Dżurko. Shipping production software since 2023. The years before were drag-and-drop builders and e-commerce templates, slowly building real skill. The current workflow took two years to sharpen.
Damaging admission: I'm not an agency. One person, strong Polish coffee, one Slack. Backends in Convex, Supabase, or whatever fits the job; frontends in Next.js, Astro, or Vite. No frameworks-for-fashion.
Act 06 · Contact
Drop me your email and what you're trying to ship. I reply from costa@meetcosta.com. No autoresponder, no sales rep, no funnel.
