Shikhar Srivastava

I’m a backend engineer with 4+ years of experience building scalable APIs, event-driven microservices, and production systems across crypto, fintech, and e-commerce. I bring deep strengths in Node.js and TypeScript, with hands-on expertise in Redis, RabbitMQ, MongoDB, PostgreSQL, and AWS-backed infrastructure—delivering services that support 100K+ users and sub-200ms real-time experiences.

In my most recent role, I re-architected rewards from a monolith into event-driven microservices with Node.js, TypeScript, RabbitMQ, Redis, and MongoDB, cutting new campaign integration time by ~50%. I built a Redis-backed leaderboard that reduced latency from ~1.2 seconds to under 200ms during high concurrency, and automated reward/airdrop workflows end-to-end, reducing manual operations by 80%+ while achieving 99.5% allocation accuracy through queue-based workloads, caching, idempotent processing, and production observability. Earlier, I engineered a Node.js/MongoDB backend for a multi-panel e-commerce platform, reducing API response latency by ~40% via indexing, caching, pagination, and background processing, and I integrated Stripe multi-currency payments, AWS S3 storage, PDF/CSV generation, and notifications.
