Mohammad Sadegh Majidi

I build the backends behind products people trust with their money and their time.

Download Resume Email Location


👋 Hi, I'm Sadegh

I started writing Python at around 15 and never really stopped. Six years later, I design and ship backends for fintech, SaaS and marketplace products — from investment and payment platforms to a vacation-rental marketplace, one of Iran's largest HTML template stores and a VPN platform with 100K+ users.

I care about the boring parts that make systems trustworthy: correctness, clean architecture, good tests and releases that don't wake anyone up at night. When I'm not shipping product, I'm usually building open-source tools.

🧭 Currently

  • 🔨 Working on the backend of Zarafza, a digital-gold trading platform, and my own product, RTLHTML
  • 📚 Learning advanced system design and polishing my English to full fluency
  • 🤝 Open to senior backend roles — Mashhad, Tehran, remote or hybrid

🛠 What I build

  • Financial systems — wallets, ledgers, payments and portfolio analytics where every number has to be right
  • Products end to end — from data model and APIs to deployment, with frontend and product teams
  • Reliable services — async workers, caching, idempotent flows and clean, testable architecture (DDD / Clean Architecture)
  • Developer tools — open-source libraries and API clients for the Python ecosystem
