About Hetti Arachchige
Senior Java Backend Engineer | Spring Boot | Microservices | AWS
Galle, Sri Lanka - 9:15 pm local time
I specialize in designing and delivering robust microservices architectures using Java and Spring Boot — from initial design to cloud deployment. Whether you need a high-performance REST API, an event-driven system, or a full cloud-native application, I deliver clean, maintainable solutions that scale.
What I bring to your project:
✔ Java & Spring Boot — Microservices, REST APIs, event-driven architecture
✔ Message Brokers — Kafka, RabbitMQ for high-throughput systems
✔ Cloud Platforms — AWS & Azure deployment, configuration & scaling
✔ Containerization — Docker & Kubernetes for production environments
✔ Databases — PostgreSQL, MySQL, IBM Db2
✔ DevOps — CI/CD pipelines with Jenkins & GitLab CI
✔ AI/ML Integration — OpenAI & NLP-powered backend features
✔ Frontend — React for full-stack delivery when needed
How I work:
I don't just write code — I take ownership. From architecture decisions to production deployment, I treat every project as if it's my own. I communicate clearly, deliver on time, and write clean, well-tested code following TDD principles.
I've worked on high-stakes financial systems where reliability and performance are non-negotiable — that mindset carries into every project I take on Upwork.
📌 Available for both short-term tasks and long-term engagements.
📌 Open to contract-to-hire opportunities.
📌 Fast response time — typically within 4 hours.
