ajithakdevEngineering systems that let humans sleep at night.
I am Ajith Kumar Karudasevai (@ajithakdev), a backend engineer crafting production systems for healthcare SaaS.
Most of my work centers around Node.js, TypeScript, DocumentDB/MongoDB, and AWS. At The Valor Solution, I co-designed an in-house Form Builder to eliminate a third-party subscription, built automated fax routing workflows, and re-architected DocumentDB aggregations to cut query latency from 26s down to 19s. Beyond cloud backends, I build open-source developer utilities and desktop tools in TypeScript, Rust, and C.
