What I'm looking for

I’m looking for a software engineering role where I can build and scale microservices and web applications, improve performance and reliability, and use AI-assisted development to ship faster—while working closely with engineers who value strong validation and quality.

I’m a software engineer who optimized a multi-billion-dollr mutual fund platform by migrating from FTL to React and Spring to Spring Boot. I brought a legacy POC in-house and built a microservices architecture for seamless third-party integrations.

I also improved performance and cost with AI-assisted development (Copilot, Claude, GPT-4), delivering 66% higher throughput per instance and faster delivery with strong human-led validation—boosting efficiency by over 30% for millions of users and billions in assets. Earlier, as an intern, I automated log management by routing error tracking from Splunk, Grafana, and Prometheus into Excel (reducing manual effort by 80%), and at Zenix Analytics I led building a website from the ground up with both front-end and back-end architecture.
