Mike Oba

I’m a Senior Full Stack Engineer with 10+ years of experience building scalable backend systems using Java and Spring Boot, while contributing to modern frontend applications with React and TypeScript. I focus on designing efficient, reliable software and solving complex engineering challenges through clean API design and strong system fundamentals.

I’ve designed microservices architectures and developed secure, high-performance RESTful APIs for large-scale cloud platforms, supporting 1M+ users. I build distributed services with Spring Boot and Spring Cloud, and I use event-driven patterns powered by Apache Kafka to enable asynchronous communication between services handling real-time transactions.

I’m hands-on with deploying cloud-native systems on AWS and orchestrating them with Docker and Kubernetes. I manage infrastructure with Terraform and CI/CD pipelines using Jenkins and GitHub Actions, and I prioritize operational excellence with Prometheus, Grafana, and AWS CloudWatch, plus ELK Stack for logging and debugging.

I partner closely with frontend teams to deliver end-to-end SaaS features using React, TypeScript, and GraphQL. From improving response time by 35% to increasing system throughput by 40% and reaching 99.9% uptime, I bring a performance- and security-minded approach backed by code reviews and architecture discussions.
