Full-stack developer specializing in React, Next.js, Node.js, and Odoo ERP. I build SaaS MVPs from scratch (React + Node.js + MongoDB), fix bugs in React, Next.js, and React Native/Expo apps, and develop or customize Odoo ERP systems and websites.
I focus on root-cause fixes over quick patches — clean, maintainable code, fast communication, and testing before delivery. Fast response time, clear updates throughout, and I won't mark a job done until it actually works.

FAQ
What types of errors do you solve?
I fix JavaScript/TypeScript logic errors, React component bugs, DOM issues, Next.js App Router & Pages Router problems, hydration/SSR errors, package conflicts, and import/alias errors.
How fast can you fix my bug?
Most simple bugs are fixed within a few hours to 24 hours, depending on complexity. Message me the error details and I'll give you an accurate ETA before you order.
What information do you need from me?
Please share the error message/screenshot, a link to your repo (GitHub/GitLab) or code files, and steps to reproduce the bug. This helps me diagnose the root cause faster.
Do you need access to my GitHub repository?
Yes, ideally. I can work with a shared GitHub repo, a ZIP file of your code, or a live deployment link (Vercel/Netlify) — whatever's easiest for you.
What if the bug turns out to be more complex than expected?
I'll let you know immediately and suggest upgrading to the Standard or Premium package, or provide a custom quote. No surprise charges — you approve before any extra cost.
Can you explain what caused the bug after fixing it?
Yes, I always include a short explanation of the root cause and what I changed, so you understand the fix and can avoid it in the future.
