At Brihat Infotech Pvt. Ltd., I co-architected KaroSauda and Brihat Books, multi-tenant GST billing and accounting platforms built with Next.js, TypeScript, and NestJS. The work accelerated invoice generation latency by 35% and supported high-concurrency ledger operations.
I also engineered the TALRR Clothing Platform, combining a commerce and inventory suite with a NestJS and Prisma PostgreSQL backend, a Next.js admin dashboard, and a customer mobile app.
On GoSQL, I engineered an embedded relational database in Go that implements the PostgreSQL Wire Protocol, so clients can connect through psql, ORMs, and drivers. I also implemented its LSM-Tree storage subsystem, ACID transactions, and vector search.
I built FiscalFlow as a digital invoicing platform with a standalone NestJS backend, Redis caching, and PostgreSQL ACID guarantees. It maintained sub-100ms response times and data consistency across high-volume invoicing records.
