Dipta Kumar Nath

Software Engineer & AI Enthusiast

Dhaka, BangladeshAvailable

Software Engineer with 7+ years of experience building scalable microservices and multi-tenant SaaS platforms. I've architected systems handling 17M+ records, led engineering teams of 11+, and delivered production-grade infrastructure across multiple industries.

🤖Beyond backend systems, I'm deeply passionate about AI — from experimenting with LLMs and building RAG pipelines to exploring AI agents and integrating intelligent features into production systems. I believe AI is the most exciting engineering frontier right now.

Proficient in NestJS, Go, Python, and TypeScript with deep experience in PostgreSQL, MongoDB, Redis, AWS, Docker, and Kubernetes. Currently based in Dhaka, Bangladesh.

What I've Built

dairyverse.org/
Live in production
01.★ FeaturedLive Product

DairyVerse

A production multi-tenant SaaS platform for end-to-end dairy farm management. Serves multiple organizations with strict per-tenant data isolation, access-based authorization for granular role controls, and a Redis-compressed caching layer (FarmPro API) that slashed high-volume farmer data response times significantly. Built on NestJS microservices with Drizzle ORM for complex PostgreSQL schemas covering farmer insights, milk collector workflows, and VLC activity classification.

AI-powered dynamic pricing engine for restaurants, live at dynpricing.ai. Integrates natively with UberEats and DoorDash delivery APIs and applies ML models to suggest optimal price points based on demand, time-of-day, and competitor signals — helping restaurants maximize revenue without manual effort.
