Shivansh Shekhar

I’m a Backend Engineer with 3+ years of experience building scalable, production-grade systems using TypeScript, Node.js, and PostgreSQL. I’ve designed multi-tenant architectures, distributed systems, and high-throughput APIs across payments, voice AI, and LLM infrastructure—shipping solutions like a production-grade multi-tenant LLM gateway with semantic caching, RBAC, and OpenAI-compatible APIs.

In recent roles, I built backend services for an enterprise Voice AI platform and a logistics tracking platform, improving background task reliability by ~75% and reducing delivery coordination errors by ~60%. I also delivered a unified payments gateway consolidating 9 payment flows across 3 providers, and built multi-tenant B2B CRM/ERP and an Identity Provider microservice (with a zero-downtime migration to Better Auth). Previously, I developed a computer vision inference pipeline (improving throughput by ~3x), scaled an SMS gateway platform to 500,000+ daily transactions with 99% uptime, and built a Telegram support chatbot that handled ~66% of customer queries—always with a strong bias toward performance, observability, and clean developer experience.
