What I'm looking for

I seek backend-focused roles building scalable, reliable distributed systems with a collaborative team, strong mentorship, and opportunities to own production services.

I am a computer science graduate focused on backend Java development, distributed systems, and scalable architectures. My hands-on experience spans Spring Boot 3, Redis, PostgreSQL, and cloud container deployments.

During an internship, I engineered a secure Billing & Subscription Management System that handled recurring billing, Stripe integrations, JWT authentication, and role-based access control. I also built a responsive React frontend and asynchronous email services to support registration and receipts.

On personal projects, I developed a distributed job scheduler using Redis Streams, distributed locks, and Java 21 virtual threads to enable scalable DAG execution, and I built Argus, a high-concurrency crypto intelligence engine with a custom scoring algorithm and automated CI/CD to AWS Lightsail.

I have been recognized with a 2nd Prize in a university research award and placed in the top 10% of a large AI hackathon; I bring a results-oriented mindset, strong problem-solving skills, and a focus on building reliable, production-ready systems.
