I work with teams that already have a product in production but are starting to get overwhelmed.
Unstable MVP, tech debt slowing everyone down, unmanageable backlog, degrading performance. The kind of situation where **adding one more developer is no longer enough**.
I am aSenior Fullstack Developer (React / React Native / Node.js)and I step in as senior support when it's time to stabilize an existing product, simplify an overly complex stack, and reduce technical debt **without starting from scratch**.
My approach is **hands-on**: I code, I refactor, I clarify.
With over 10 years of experience across **frontend, mobile, and backend**, I work with development teams as well as CTOs or more business-oriented profiles.
Typical scenarios where I get involved:
- React / React Native application in production but difficult to maintain
- Degrading performance
- Accumulated technical debt
- Need for a senior perspective to quickly bring order
