Full-Stack Developer & Product Architect

Languages
Persian (Native) · English (Professional working)

Full-stack developer and IT manager with 5+ years of experience in fintech, PropTech and e-commerce. As IT Director and shareholder at a PropTech startup I led the product through seven platform generations — from a React Native + PHP app to a Next.js, Directus and Go stack with GIS map layers and Redis caching.

I specialise in real-time financial systems, trading platforms and location-based delivery apps, and I care about clean architecture, pragmatic technology choices and shipping production-ready software. I'm available for consulting, freelance projects and senior engineering roles.

How I work

  • 01

    Own the whole thing

    I'm happiest when one person understands the product from the database row to the pixel. Fewer hand-offs, fewer surprises.

  • 02

    Boring where it counts

    Proven tools for money, auth and data. I save the novelty for the parts users actually feel.

  • 03

    Measure, then optimise

    Concurrency, caching and queries get profiled before they get clever. Correctness first, then speed.

  • 04

    Ship in slices

    Small releases behind real usage beat big-bang rewrites — I've migrated a live product through seven generations without stopping it.
