Mykyta K.
About this gig
Having issues with your React, Next.js, Supabase, API, or deployment setup?
I will help you investigate and fix bugs in custom web apps, including frontend errors, broken components, API issues, Supabase problems, build errors, deployment problems, and responsive/layout bugs.
I can help with:
- React / Next.js bugs
- JavaScript / TypeScript errors
- API route and integration issues
- Supabase auth, database, or query problems
- Vercel / Cloudflare / deployment / build errors
- Broken forms, buttons, pages, or app flows
- Frontend layout and responsive issues
Please send the error message, screenshots, steps to reproduce the issue, and access to the relevant code/repository when needed.
Important: this gig is for custom React/Next.js/Supabase web apps. I do not work on WordPress, Shopify, Wix, Elementor, or template-builder issues in this gig.
Message me before ordering so I can confirm the issue fits the package and recommend the right option.

Hi, I'm Mykyta. I build practical AI agents, AI-powered apps, automations, and internal tools for businesses. My focus is real workflows: document processing, knowledge-base assistants, support/admin agents, dashboards, API integrations, and repetitive work that slows teams down. I can help turn a messy process into a clear, working system with the right data, logic, review flow, and deployment setup.

FAQ
Should I message you before ordering?
Yes. Please message me first with the bug details, screenshots, error messages, and steps to reproduce it. I’ll confirm whether the issue fits the package.
What do you need to start?
I usually need a clear description of the bug, screenshots or screen recording, error logs, steps to reproduce, and access to the relevant code or repository if code changes are required.
Do you work with WordPress or Shopify?
No. This gig is focused on custom React, Next.js, Supabase, API, and JavaScript/TypeScript web apps. I do not handle WordPress, Shopify, Wix, Elementor, or similar builders here.
What counts as a small bug fix?
A small bug is usually one clearly reproducible issue, such as a broken button, layout issue, console error, small component bug, build error, or simple frontend issue.
Can you fix API or Supabase issues?
Yes. I can help with API routes, broken requests, Supabase auth, database queries, permissions, form submissions, and integration-related issues.
Do you guarantee every bug can be fixed?
Most bugs can be fixed, but some issues depend on code quality, third-party services, missing access, or project complexity. I’ll review the issue first and tell you what is realistic.
What if the bug is more complex than expected?
If the issue is larger than the selected package, I’ll explain the situation and suggest the right package or a custom offer before doing extra work.
Do you provide documentation?
Yes. Standard and Premium packages include fix documentation. Premium also includes detailed code comments where useful.
