You will get a seamless legacy Spring Boot upgrade to the latest stable version
Project details
Upgrading legacy Spring Boot applications can be risky and time-consuming without proper planning. This project offers a structured, low-risk upgrade path to bring your Spring Boot backend to the latest stable version, ensuring improved performance, better security, and long-term maintainability.
Whether you just need a version bump or a full refactoring with CI/CD enhancements, I provide tailored solutions that match your goals, codebase complexity, and delivery timelines. Each tier includes code analysis, upgrade planning, and testing to ensure the upgrade doesn’t break your app.
I bring 14+ years of Java backend experience, currently leading enterprise-grade projects. You’ll get clean code, detailed documentation, and zero guesswork throughout the process.

About Gihan
Senior Technical Lead | Microservices | AWS Cost Optimization
Colombo, Sri Lanka - 6:06 pm local time
When enterprise systems scale, they face two major bottlenecks: runaway cloud infrastructure waste and crushing technical debt. I partner with CTOs, VPs of Engineering, and technical founders to transform unstable architectures into highly efficient, high-performance engines that comfortably serve millions of users.
💡 Proven Enterprise ROI Impact:
✅ 60% Cloud Cost Reductions: I analyze, right-size, and consolidate complex AWS infrastructure (ECS, RDS, Lambda) to maintain peak performance while slashing operating costs. I saved a global EdTech leader 60% on their annual AWS footprint.
✅ 200% System Reliability Boost: I eliminate data bottlenecks and perform deep load-testing to elevate system resilience to strict enterprise SLA standards.
✅ Monolith to Microservices Migration: I systematically decouple legacy architectures into highly agile, independent microservices, increasing overall development velocity by 100%.
🔧 Core Technical Domain Expertise:
✅ Backend Ecosystem: Java (8 to 21), Spring Boot, Spring Cloud, Hibernate, RESTful APIs, Microservices Architecture.
✅ Cloud & Infrastructure (AWS): EC2, Lambda, ECS, EKS, RDS, SQS, SNS, S3, Docker, Kubernetes, CI/CD Pipelines.
✅ Databases & Storage: MySQL, Oracle, MongoDB, performance tuning, and query optimization.
✅ Engineering Leadership: Expert in guiding, mentoring, and scaling cross-functional agile teams of up to 14 engineers across global time zones.
