What I'm looking for

I’m looking for a software engineering role where I can build full-stack features with secure, resilient backends and thoughtful system design—using CI/CD and testing to ship reliably, and applying responsible AI to solve real production problems.

I’m a Java full-stack software engineer with 2 years working across backends, frontends, databases, and AWS deployments. I design and execute end-to-end solutions through development and technical troubleshooting, keeping upstream/downstream system behavior in mind.

In my current role at Cognam Technologies, I’ve built Spring Boot REST services with a React.js front-end, Oracle 23ai persistence, and AWS deployment. I improved transaction-heavy performance with a 78% p95 latency reduction (about ~800 ms to ~180 ms) and maintained “zero downtime” during a live incident through distributed rate limiting.

I also engineer with secure, compliant patterns—maker-checker governance with audit trails and application-level encryption (RSA-OAEP, AES-256-GCM) for sensitive financial data. I use AI-assisted development responsibly by validating outputs via peer review, automated testing, and secure coding standards, and I ship features like production RAG with data-sensitivity controls.

Decomposed a monolithic notifications system into a Kafka-backed microservice, decoupling campaign and transaction producers so non-engineering teams could configure templates and audience targeting independently. Contributed to migrating a Struts admin portal to a Spring Boot + React.js microservices architecture by containerizing services with Docker and establishing CI/CD pipelines.
