What I'm looking for

I seek hands-on engineering roles where I can lead backend and microservices architecture, work cross-functionally with stakeholders, mentor teams, and deliver scalable, high-impact solutions in a collaborative, growth-oriented environment.

In my current role at Americar Tech, I lead the design and implementation of microservices architectures, working hands-on with code while guiding my team.

I'm known as the go-to person for complex technical problems—I thrive on debugging difficult issues, optimizing slow systems, and implementing caching strategies that make a real difference. My approach combines technical leadership with practical problem-solving.

I'm looking for remote opportunities where I can contribute my expertise in backend development, system architecture, and performance optimization while continuing to grow as a technical leader.

Key strengths: NestJS, TypeScript, Microservices, Performance Optimization, PostgreSQL, MongoDB, Redis, Technical Problem-Solving, Team Leadership.
