Sandeep H M

I am a Senior Backend Engineer with 4 years of experience specializing in Node.js, TypeScript, and AWS. I have partnered with global startups and SMEs to architect and scale fault-tolerant distributed systems. At my most recent engagement, I engineered a URL shortening service from the ground up, scaling it to handle 15M+ redirects using a cache-aside strategy on Redis, which eliminated 100% of external provider costs. I also have deep experience in AI orchestration, having built pipelines that orchestrated GPT-based agents using Temporal workflows to manage non-deterministic AI outputs. On the fintech side, I developed automated refund engines and webhook microservices for PayU and Stripe that cut transaction failure rates by 18%. I thrive on solving complex architectural bottlenecks, optimizing databases, and owning deployments end-to-end. I am looking for a Senior Backend role at a high-ownership product company where reliability and scale are mission-critical. I work best in async-first, remote environments and have a proven track record of shipping independently.
