Hello, I'm
Raju Mondal
|
I build backend systems, mobile applications, and search engines for production platforms. 5+ years of commercial experience delivering solutions that real users depend on.
About
I'm a software engineer based in Dhaka, Bangladesh with 5+ years of commercial experience. I specialize in building backend systems with Laravel and creating cross-platform mobile apps with Flutter.
My most notable work includes building the product search engine for eBitans — Bangladesh's leading e-commerce platform builder — and leading the full backend development of VarsityResource.com, an academic opportunity platform serving 945+ registered users.
I also published a Flutter Android app — Biddut Bill Calculator — with 1k+ users on the Google Play Store.
Currently, I'm expanding my skill set into AI integration, working with LangChain, ChromaDB, and semantic vector search — building on the foundation of traditional search systems I've already shipped in production.
