What I'm looking for

I am seeking backend/cloud-focused roles where I can build scalable, secure microservices, improve automation and reliability, and grow within a collaborative, product-driven team.

I am a Software Development Engineer with 3+ years of hands-on experience building secure, scalable applications using Java, Spring Boot, and PostgreSQL.

I have implemented KYC/KYB automation, API rate-limiting, notification systems, and enterprise features for clients such as JSW ONE, improving onboarding times and operational efficiency.

My work spans microservice architecture, event-driven systems, and cloud platforms (AWS, GCP), with a strong emphasis on test-driven development and robust integration testing.

I deliver product-focused solutions—automating deployment workflows, designing transformation microservices, and creating features that increase user engagement and retention.
