Rachit Girish Kulkarni

I’m a Software Development Engineer who pairs backend engineering with performance, security, and fast iteration. I’m also pursuing a Master of Science in Computer Software Engineering while delivering production work.

At ASU Enterprise Technology, I translated stakeholder audit requirements into RESTful API contracts using Flask and React, powering a compliance dashboard across 94 web properties for 3 product teams. I replaced a sequential Python audit pipeline with asyncio and aiohttp using semaphore-bounded concurrency, reducing wall-clock runtime from 8 hours to 28 minutes across 94 I/O-bound calls. I also enforced parameterized queries, role-based access controls, and input validation, driving OWASP-class vulnerability findings to zero across two consecutive internal security reviews.

Previously at Larsen and Toubro Technology Services, I built Python backend services exposing RESTful APIs to 4 downstream teams, with Redis caching handling read peaks above 3,000 concurrent device connections in sustained load tests. I restructured PostgreSQL schemas with composite indexes and targeted query rewrites, cutting device-telemetry query time by roughly 60% across tables exceeding 10M rows. I containerized 6 platform services with Docker and Kubernetes, authored Helm charts, and automated testing/build/release via GitHub Actions—shortening the release cycle from roughly 4 days to under 2.5 days across 8 platform releases.

My projects reflect the same standards: reliable systems, measurable outcomes, and observability. From a saga-orchestrated event processing platform achieving 99%+ delivery reliability across 180K benchmark events, to an API gateway/auth service that reduced auth latency from 180ms to under 70ms at 500 RPS, I focus on robust behavior under real load. I’m also building applied AI systems with a RAG knowledge search platform (FastAPI, LangChain, Gemini, pgvector) and have been recognized with awards for engineering impact and research-driven innovation.
