About this gig
I fix bugs and add features in Next.js and React apps. I work with TypeScript and Tailwind every day on my own live products, including performance work: I cut the 3D and AR file stely.izes of my SaaS by about 65% and fixed slow image loading, measured on real phones.
Live work you can open today:
Serva (servamenu.com): a SaaS for restaurants with multilingual QR menus, 3D/AR food previews and an AI menu assistant.
Beacon (beaconfolio.vercel.app): a portfolio tracker with a tested web app and API (16 end-to-end and 42 API tests).
WebsiteAudit AI: Lighthouse audits turned into clear AI reports.
What I take on:
Bugs: crashes, broken layouts, hydration errors, failing builds, slow pages, API and form problems.
Small features: forms, auth, payments, dashboards, filters, i18n.
Performance fixes backed by Lighthouse numbers.
How it works: send me the repo access or a zip, a description of the problem and, if you have them, the steps to reproduce it. I find the cause, fix it, test it on desktop and mobile, and send you a short note on what was wrong and what I changed. Code goes back as a pull request or a patch, whichever you pref

I build and fix web apps with Next.js, React, TypeScript and Tailwind. I run Serva (servamenu.com), a live SaaS for restaurants with multilingual QR menus, 3D/AR food previews and an AI menu assistant. I also make short product motion videos. I work AI-accelerated, so small jobs that take others a week often take me a day or two, with testing included. I reply within a few hours, show progress daily, and don't call a job done until it works on your device.

FAQ
Do you need access to my repository?
Yes, read access to the code is needed. A GitHub invite or a zip both work. I never need production passwords, and I will tell you if I need any keys for testing.
What if you cannot reproduce or fix the bug?
I tell you early, within the first day, with what I found and what I would try next. If a bug is bigger than the package, I suggest the right one before going further.
Can you work on a codebase someone else wrote?
Yes, that is most of this gig. I keep changes small and in your existing style, and I do not refactor things you did not ask me to touch.
