Junior Software Engineer @ AppifyLab
Ramendra Kumer Singha
Software Engineer
Full-stack software engineer with a competitive-programming backbone. I build clean, efficient web applications, and I'm currently focused on backend development and system architecture — while actively learning system design.

A bit about me
I'm a Computer Science & Engineering graduate from Sylhet Engineering College (CGPA 3.84/4.00) and a software engineer at AppifyLab, where I work across the frontend, backend, and database layers of production products.
My foundation is competitive programming — 1800+ problems solved across Codeforces, CodeChef, AtCoder, LeetCode, CSES, and LightOJ. That background shapes how I write code: I care about correctness, efficient algorithms, and keeping things simple.
Day to day I build full-stack web applications with React, Next.js, and AdonisJS. Right now I'm focused on backend development and system architecture, and I'm actively learning system design.
