Available to hire
I’m Vinuja Pium Jith, a versatile software engineer who enjoys building reliable systems across backend, full-stack, and data pipelines. I’ve developed and deployed microservices and REST APIs using Java Spring Boot, PostgreSQL, and React/TypeScript, with a strong focus on clean code, SOLID principles, and practical user experience improvements.
I also work on event-driven architectures and production-grade observability—integrating tools like Kafka, Micrometer, Zipkin, Grafana, Splunk, and implementing unit/load testing to improve performance and reliability. On top of that, I’ve contributed to data engineering workflows (Azure Data Factory/Databricks, PySpark, ETL with medallion layers) and provided production support and troubleshooting for distributed systems.
