Over the past 4\.5\+ years, I've worked across the full stack: designing event\-driven architectures with Spring Boot and Apache Kafka, building React front\-ends that don't lag under load, and securing APIs with JWT\-based auth that actually holds up in production\. At TCS, I engineered RESTful microservices that cut P95 latency by 20%, built test suites hitting 90%\+ code coverage, and shaved 30% off page load times through lazy loading and smart caching — the unglamorous work that makes systems reliable at scale\. Lately, I've been going deeper into GenAI\. I'm building Spring AI and RAG\-based features that plug LLM capabilities directly into enterprise Java systems — turning "we need an AI feature" into something that actually ships to production\. I'm AWS Certified \(Developer – Associate\) and comfortable across Lambda, API Gateway, and serverless workflows\. What I care about: → Systems that stay fast and reliable as traffic scales → Clean, testable code — not just code that works today → Bridging traditional enterprise Java with modern AI capabilities, instead of treating them as separate worlds\. Currently exploring opportunities at product\-led engineering teams where I can work on systems at real scale — happy to connect if that's you\. ## Location Pune District ## AI stack claude gemini github copilot claudecode ChatGPT Microsoft Copilot ## Work experience Consultant at Capgemini, May 2026 \- Present · 4 mos, Pune, Driving enterprise integration and GenAI initiatives — building event\-driven data pipelines and bringing LLM capabilities from prototype into production Java systems\.
