Backend-focused software engineer specializing in scalable Java services and cloud-native systems.

What I'm looking for

I am seeking backend/cloud engineering roles focused on designing scalable, reliable services, strong observability, performance optimization, and collaborative Agile teams.

I am a backend-focused software engineer with hands-on experience building high-throughput, reliable services using Java and AWS. I have delivered production features at scale, including a generic template engine for multi-channel notifications and a real-time metrics pipeline.

At Aptiv, I built event processing with Kinesis, Lambda, and DynamoDB achieving <100ms latency and full reliability, and implemented API throttling solutions that reduced latency by 40% during peak loads. I also drove observability improvements through CloudWatch dashboards and iterative load testing.

During my internship I contributed to backend development, unit testing with JUnit and Mockito (95%+ coverage), and collaborated closely with frontend teams to define API contracts and ensure smooth integration. I adopt Agile practices and participate actively in code reviews and sprint planning.

I enjoy solving challenging problems, demonstrated by solving 900+ LeetCode problems and maintaining a strong contest rating, and I seek roles where I can design scalable systems, optimize performance, and mentor others while continuing to grow in cloud-native architectures.
