About

Last year I cut one of our APIs from 2700ms to 127ms — a 95% drop — by rearchitecting the data layer from Prisma to Mongoose. That kind of measurable, shippable impact is what I chase. I'm a Backend Engineer at Redrob, designing and shipping high-throughput systems in Node.js, NestJS, TypeScript, and MongoDB. A few things I've built recently: → A CSV processing pipeline that dropped download time from 5 minutes to under 30 seconds (90%+ faster) via batched, parallel execution → A resilient automated retry framework on NestJS + Redis + AWS that cut fatal error rates by 40% → A plug-and-play enrichment framework that reduced new provider onboarding time by 20–30% → An LLM prompt-engineering approach that brought token usage from 1000+ to 590 while maintaining reliable JSON outputs I graduated from MSIT in 2024 (CGPA 9.28, Computer Science) and care about clean architecture, measurable performance wins, and systems that don't fall over at 3 AM. Currently going deep on distributed systems, message queues, and cloud-native backend design. Open to Backend / SDE roles where the problems are hard, and the scale is real. 📬 aiyushkanojia@gmail.com · GitHub: https://github.com/aiyushkumar07
