A Bit About Me

Hello! I'm Saif, a software engineer based in Dhaka, Bangladesh. I enjoy building things that live on the internet — from marketing websites to complex full-stack applications, everything in between.

My journey started in 2019 when I decided to hack together a custom theme — turns out tinkering with CSS teaches you a lot! Fast-forward to today: I've built software for agencies, large corporations, and startups across three continents.

Technologies I've been working with recently:

▹ JavaScript (ES6+) ▹ TypeScript ▹ React / Next.js ▹ Node.js / Express ▹ GraphQL ▹ PostgreSQL ▹ Three.js ▹ Solidity / Web3
