Astro engines, custom Next.js builds, full-stack SaaS — shipped from a single keyboard. AI-assisted, hand-architected, agency-grade quality at solo-dev pricing.
Act 01 · How I work
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.
Act 01 · Solo dev
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 01 · The toolkit
Convex or Supabase on the backend, Cloudflare for the edge, Next.js / Astro / Vite on the frontend — picked per job, not per fashion. Open to whatever new stack solves the actual problem.

Hand-coded Astro engines per market. 20+ unique city pages. Lead capture wired to your CRM. Submission-grade schema, real EEAT signals, Cloudflare-fast everywhere.

Bespoke marketing sites in Next.js with the polish your competitors only buy from agencies — and a price tag that doesn't require Series B.
Act 02 · Three lanes · 3 of 3
Full-stack SaaS from idea to revenue. Convex or Supabase for the backend, Clerk for auth, Resend for the email loop, and a UI you'd actually keep open.
