## About

Hi, I'm Snehil, Backend Engineer passionate about building scalable backend systems and event\-driven architectures that perform reliably under high throughput\. I have 2\+ years of experience building production\-grade backend systems using Java, Spring Boot, Node\.js, TypeScript, AWS \(Lambda, SQS, SNS\), NestJS, and microservices\. I specialize in event\-driven design, serverless migrations, and end\-to\-end feature ownership from idea to deployment\. At Cimpress: • Migrated a high‑throughput shipment processing service \(1M\+ events/day\) from ECS to AWS serverless – achieved zero‑downtime deployment, 35% cost reduction, 50% lower latency, and handled 2x peak traffic\. • Designed a credit‑based monetization system for GenAI Logomaker \(checkout \+ payment webhooks\) – load‑tested to 10K\+ orders/day\. • Built data pipelines processing 50K\+ records/day with 25% fewer parsing errors\. Beyond work: • LeetCode Knight \(1975 rating, 1500\+ problems solved\) • Oracle internship – built multi‑threaded metrics collection system \(Java, multithreading, JDBC\) • CRYPTEC Coding Battle & MRTM 23 participant Certifications: Event\-Driven Microservices \(CQRS, Saga, Event Sourcing\) • AI/DSA Tech Stack: Java • Spring Boot • Node\.js • TypeScript • AWS \(Lambda, SQS, SNS, ECS\) • NestJS • Microservices • MySQL • MongoDB • C • System Design I'm currently seeking backend / full‑stack roles where I can own features end‑to‑end, build systems that scale to millions of events, and grow into agentic AI system design without leaving backend engineering behind\. Always open to collaboration, problem‑solving, and backend innovation\. Let's connect\!
