Curriculum Vitae

Shahriar Hossain

Full-Stack developer with a product mindset and experience shipping SaaS dashboards and IoT platforms into real usage. I’ve worked as a technical lead and builder on projects where reliability, UX, and deployment actually matter.

I’m looking for roles where I can own features end-to-end: from API design and database schema to React/Next.js UI, deployments, and monitoring.
