About this gig

I help businesses fix, improve or upgrade their existing web applications and custom CRM systems.

Whether it's a broken feature, outdated architecture or a full rebuild I step in, clean things up and get them running smoothly again.

I work with modern stacks like React, Next.js, Firebase, PHP, Python and offer full integration of databases (e.g. Firestore), APIs, user authentication and dashboards.

Need automation? I also implement process flows with n8n or custom scripting where needed.

From bug fixes to complete refactoring I provide clean, maintainable code and production-ready solutions tailored to your needs.

Lets talk about whats not working and fix it properly.
