Hi, my name is

Tanzim Khan Shanto.

Software Developer · System Designer · Problem Solver

01.About Me

I started programming out of curiosity, learning with limited resources and a strong interest in problem-solving. Early exposure to algorithms and competitive programming shaped how I approach challenges logically and efficiently.

I moved from solving problems to building real-world applications, working across the stack with modern frontend frameworks, databases, and APIs. I’ve built scalable features, real-time systems, and production-ready interfaces while collaborating closely with teams.

I’m currently focused on building fast, maintainable web applications with React, Next.js, and TypeScript, while continuing to deepen my backend and system design skills through hands-on projects.
