What I'm looking for

I seek backend roles at product-focused teams where I can drive performance improvements, own end-to-end systems, work on 0→1 product growth, and apply cloud/DevOps practices in collaborative Agile environments.

I am a backend-focused software engineer with three years' experience building queue-management and product-oriented applications and contributing to 0→1 journeys.

I design and implement performant RESTful APIs using Java 8, Spring Boot and Spring Security, improving response time by 30% and reducing error rates by 20%.

I reduced API latency from 5–15+ seconds to under 1 second through query optimization, indexing and Redis caching. I redesigned appointment scheduling to boost availability by 40% and integrated payments with Razorpay and PayPal.

I refactored CI/CD pipelines and Jenkins builds, cutting build times by 67%, engineered secure OTP notification services and audit logging, and documented technical workflows to onboard new hires. I thrive in Agile teams and prioritize secure, maintainable systems.
