Mahmudul Alam here! 👋 AFull-Stack Software Engineer who's absolutely passionate about building beautiful, performant frontends withReact & Next.js, diving deep intoWeb3, and crafting solidSystem Architecture.

Hailing from Bangladesh 🇧🇩 and currently based in Dhaka, you'll find me wearing multiple hats:Independent Contributor (IC) atCreative Crowdfunding Protocol (CCP) andBackend Lead atMavu (a minipay app for microworkers). When I'm not coding, I'm probably learning something new or contributing to the Web3 community!

Started from the bottom (literally, with vanilla JS 😅) and here's how it went:

2019-2021: Mastering the fundamentals - Vanilla JS, jQuery, DOM manipulation, CSS3, HTML5
2021-2022: Fell in love with React (Class → Functional Components), dove deep into Frontend Development
2022-2024: Went full-stack mode - Django, Express, and got hooked on Web3 Integration
2024-2025: Leveled up with System Architecture, Smart Contracts, and Blockchain
2025-Present: Pushing Frontend Architecture boundaries, exploring DevOps, and diving into Cloud Native

What's keeping me busy these days:

• Frontend Magic: Next.js, React, TypeScript, Server Components, and exploring advanced React patterns
• Backend Stuff: Express, Django, TypeScript - keeping the APIs happy
