About this gig

I fix broken web apps, APIs, and backend systems fast using Python, JavaScript, Rust, C++, Java, and more.

I solve frontend bugs (React/Next.js errors, broken UI), API failures (Stripe/PayPal/webhooks), database issues (Supabase/PostgreSQL), backend logic (auth/payments), and deployment problems (Vercel/Railway).

Clear packages from $35, source code included, 1-5 day delivery. Message me your error + repo link.
