I build distributed backend systems, from LLM remediation platforms to high-scale data services.
IndiaWhat I'm looking for
At CommerceIQ, I led an LLM-powered multi-agent remediation platform that diagnoses and automatically fixes retail web-data extraction failures across 1,000+ retailers. It handles 250+ production anomalies per day and reduced manual triage time by 80%.
I designed its end-to-end code-repair pipeline, from configuration retrieval and fix generation through live URL validation and automated PR creation, reaching 85–90% accuracy. I also architected an asynchronous export service delivering 500+ exports daily with a 99.9% success rate.
Previously at Cashe, I cut customer and support API response times from five seconds to 100ms through caching and query optimization. I built configurable partner onboarding, delivered a credit-limit-increase journey in two weeks, and automated KYC fraud and image-liveness checks with a 99% success rate.
At Rakuten, I built for a cloud crawling platform processing five million web pages daily, delivered 50+ internal APIs, and contributed to storage changes that cut costs by 30%. I enjoy taking ambiguous 0-to-1 systems from design through production and on-call ownership.
