A developer who likes shipping things that actually feel good to use.

I'm Jahanara Khatun, a MERN Stack Developer currently with Technomax System (Dubai). Over the last 4+ years I've designed and shipped scalable web applications — B2B marketplaces, enterprise platforms, employee management systems, admin dashboards and customer-facing portals.

My day-to-day is React.js, Next.js and TypeScript on the front, with Node.js, Express.js, MongoDB, PostgreSQL and MySQL on the back. I've led frontend architectures with Redux Toolkit, RTK Query, Material UI, Tailwind CSS and React Hook Form, integrated Microsoft Graph & SharePoint APIs, payment gateways, and built secure auth flows used by both internal teams and external customers.

I'm deeply interested in AI-assisted development and agentic workflows — using OpenAI APIs, prompt engineering, Claude Code and Codex to ship better software, faster. I love building intelligent systems that automate workflows and quietly improve everyday operations.

On the infra side I'm comfortable with Docker, CI/CD, Azure DevOps, GitHub Actions and modern deploy targets. I care about clean code, accessibility, performance and the small details that make a product feel premium.

What I'm great at

  • · Production-ready Node.js APIs
  • · Admin dashboards & B2B/B2C platforms
  • · Microsoft Graph / SharePoint integrations
  • · AI-assisted workflows & OpenAI APIs
  • · Performance, DX, and design fidelity
