What I'm looking for

I’m looking for a team where I can build production-ready Flutter mobile apps and scalable backend systems, working on REST APIs, secure authentication, and performance improvements to ship reliable features end to end.

I’m a Flutter and backend developer with 2+ years of experience building production-ready, scalable systems. At Spark, I engineered backend platforms supporting 1000+ users, delivered and supported 8+ RESTful APIs, and optimized database queries to cut average response time by 30%.

I also focused on reliability and security, designing secure authentication using JWT and RBAC and reducing production defects by 25% through systematic debugging and refactoring. At falcon, I built cross-platform Flutter apps with Dart, connected them to backend RESTful APIs, created adaptive UIs with robust state management, and improved overall application performance.
