Salauddin Majumder

I am an AI Engineer at Betopia Limited and a full-stack mobile & web developer. From building Bangladesh's First AI Law Assistant to launching production apps and teaching 1000+ students, I turn complex ideas into real, usable products.

The Story Behind The Code

🎯 My Mission

Turning Impossible Ideas Into Working Reality

What if legal help was just a tap away? That question led me to create UkilGiri — Bangladesh's first AI-powered law assistant that's changing how people access justice.

Today I work as an AI Engineer at Betopia Limited and build as a full-stack mobile & web developer. I've completed full-stack web development, built QuizInfinite (AI quizzes in 53+ languages), taught C Programming & Data Structures to over 1000 students at Monozog, and developed TriVashi — an AI system that translates regional Bangla dialects.

"I believe the best products solve real problems for real people. Every line of code I write has purpose."
