You will get a complete Java & Spring Boot Bug Fix & Code Review
Project details
With 10+ years of enterprise backend experience at three of Central America's largest banks, I bring the same zero-tolerance-for-bugs mindset to your Java and Spring Boot project. I don't just patch symptoms — I find root causes and deliver clean, lasting fixes with full documentation so you understand exactly what was wrong and why. Whether it's a REST API throwing 500 errors, a database query killing performance, or a microservice behaving unexpectedly in production — I've seen it and fixed it.

I'm a Technical Lead with 10+ years of experience building scalable microservices, REST APIs, and system integrations for the banking, payments, and fintech industry. I've worked on platforms handling high transaction volumes where reliability and security are non-negotiable.

✅ Event-driven systems with Apache Kafka
✅ Cloud deployments on AWS and OpenShift
✅ CI/CD pipelines and DevOps best practices
✅ Oracle, SQL Server & PostgreSQL — design, optimization, and migration
Why clients trust me:
I don't just write code — I think like an architect. I ask the right questions upfront, communicate clearly throughout, and deliver systems built to last.
