About

Full-Stack Engineer with 5+ years building platforms that serve 20M+ daily active users at 120K requests per second with 99.99% SLA. Currently an SDE-3 at Unstop, where I architect cloud-native microservices on AWS EKS and lead Gen-AI/LLM integrations adopted by 20+ Fortune-500 enterprises. I designed 5 Kubernetes-based microservices using CQRS, sharding, and caching — cutting infrastructure costs by 45% and boosting query performance 3×. I've built real-time AI interview systems with GPT, LiveKit, and WebSocket that reduced candidate drop-off by 38%. I also ship frontend experiences in Angular (RxJS, NgRx) and React Native, with apps reaching 1M+ users. Core strengths: System Design (HLD/LLD), Event-Driven Architecture, CI/CD Pipelines, and translating complex AI capabilities into production-grade products. Stack: Node.js, NestJS, Python, Java, Spring Boot, Angular, React Native, AWS (EKS, Lambda, SQS, S3), Kubernetes, Docker, PostgreSQL, MongoDB, Redis, Elasticsearch, Kafka, Datadog. Oracle Cloud Infrastructure 2025 Certified — Foundations & AI Foundations.
