What I Bring to the Table

Product Engineering Backend & Infrastructure Intelligent Tools
Responsive product interfaces, dashboards, admin systems, and complete user flows APIs, databases, authentication, payments, storage, containers, and deployment AI integrations, automation workflows, developer tooling, and practical desktop utilities

I care about the full journey: understanding the problem, making the right tradeoffs, shipping the product, and improving it after release.

Core Stack

Next.js, React, TypeScript, Tailwind CSS, Python, FastAPI, PostgreSQL, Redis, Docker, Nginx, Git, and GitHub

Also experienced with authentication, payments, media storage, API integrations, AI workflows, and production deployment.

How I Work

  • Product-minded — technology serves the user and the outcome.
  • End-to-end — interface, backend, data, deployment, and iteration belong to one system.
  • Practical — I favor clear architecture, maintainable code, and tools that earn their place.
  • Persian-first, globally usable — local problems deserve world-class product thinking.

Have a useful idea worth shipping?

I am open to product collaborations, full-stack projects, and ambitious developer-tool ideas.
