Sobre este Serviço

Are your servers crashing under load? Are your database queries too slow? Or do you need a highly scalable microservice built right the first time?

I am a Senior Backend Engineer with extensive experience building business-critical microservices in the high-stakes banking and telecom sectors. I do not just write code; I architect systems that are scalable, secure, and built for long-term maintainability.

What I specialize in:

  • Performance Tuning: Profiling Java applications to find memory leaks and CPU bottlenecks.
  • Database Optimization: Rewriting inefficient PostgreSQL queries and fixing Hibernate mapping issues.
  • API Design: Architecting clean, secure, and lightning-fast RESTful APIs.
  • System Architecture: Migrating monolithic applications to modern Spring Boot microservices.

Coming from a disciplined background as a Maritime Officer, I approach complex architectural challenges with a calm, highly analytical mindset. I bring an enterprise-grade, production-first mentality to every project I touch.

Lets fix your backend. Send me a message before ordering so we can discuss your exact technical requirements!
