Frontend Developer · Dhaka, Bangladesh

Design engineerbuilding for the web.

I turn rough ideas into working, on-brand web apps. I design directly in code, so there's no mockup stage, just the real product.

What I built

I built the whole platform on my own. Recruiters move candidates through each job's hiring steps, book interviews and send email, all in one app. AI reads each resume and scores it against the job. Once someone is hired, they move into client account management.

Solo build: research, design, code, AI and deployment. I still maintain it.

Key features

  • Drag-and-drop hiring pipeline for every job
  • AI reads and scores resumes against each job
  • Interview scheduling with Zoom links, scorecards and email in and out
  • 8 user roles, each with their own permissions

What I built

A chat you talk to. Say what you ate or send a photo, and the AI logs the meal, fixes mistakes and answers questions about your day. You can set a health goal and track it by logging your food and weight. I built it all on my own, from the design to the Firebase backend.

Solo build: design, code, the AI agent, tests and deployment.

Key features

  • Log by chatting: one message can log a meal and your weight
  • Photo logging: snap your plate and get an estimate you can correct
  • Goals and progress: set a health goal and track your weight and calories
  • Private by design: export or delete all your data anytime
