Mahmudul Alam here! 👋 A Full-Stack Software Engineer who's absolutely passionate about building beautiful, performant frontends with React & Next.js, diving deep into Web3, and crafting solid System Architecture.

Hailing from Bangladesh 🇧🇩 and currently based in Dhaka, you'll find me wearing multiple hats: Independent Contributor (IC) at Creative Crowdfunding Protocol (CCP) and Backend Lead at Mavu (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
• Web3 Adventures: Smart Contracts, MetaMask, RainbowKit, Privy, Ethers.js, EVM
• Infrastructure: PostgreSQL, Redis, BullMQ, PM2, CI/CD pipelines

Always learning something new! Currently diving into:

• Golang - Expanding backend horizons
• DevOps & Infrastructure - Getting my hands dirty with Docker, Kubernetes, Terraform, Pulumi, Ansible
• Container Internals - Understanding what makes containers tick
• Infrastructure as Code - Terraform and Pulumi are my new best friends
• Cloud Native - Exploring architecture patterns and scalability strategies

• AlgoExpert Certificate (October 2023) - View Certificate
• FrontendExpert Certificate - View Certificate
• SystemsExpert Certificate (October 2023) - View Certificate
• Blockchain Olympiad Bangladesh 2022:
  • 🥇 Gold Award (Professional Category) - Team Leveor - View Certificate
  • 🥈 Silver Award (Professional Category) - Team Universal Machine - View Certificate
