## Quick answers

- **What do you do?** I am Mohammad Zafardoost, a senior backend engineer based in Muscat, Oman. I build distributed and financial systems — exchanges, wallets, custody, payments and platform infrastructure — in Node.js and TypeScript, and I have led engineering teams as a Technical Lead.
- **What was your most recent role?** From June 2024 to August 2026 I was Technical Lead at Dana Blockchain Solutions, where I led a ten-person team and owned the architecture, delivery and infrastructure of three fintech platforms — BitBaax, TetherBaax and Goldmim — all handling live custody of customer assets.
- **Which technologies do you work with?** Node.js and TypeScript on the backend; PostgreSQL, MongoDB and Redis for data; RabbitMQ, MQTT and WebSocket for messaging and real-time systems; Docker, Kubernetes and GitLab CI for delivery. I also integrate LLM APIs in production products.
- **What kind of systems have you built?** Fifteen production systems across fintech and blockchain, AI products, commerce and payments, logistics, telecom, IoT and platform infrastructure — from a centralized crypto exchange and a gold trading platform to a company-wide API gateway and an AI fitness coach.
- **Do you have experience leading teams and hiring?** Yes. I led a ten-person engineering team at Dana Blockchain Solutions, conducted more than 250 technical interviews at Part Software Group, and taught backend development to around 100 engineers across four cohorts, 25 of whom were hired into the company.
- **What is your background in security?** Before software engineering I spent three years, from 2016 to 2019, as an IT security specialist delivering network infrastructure and security projects — firewalls, IDS/IPS and endpoint protection — and I hold CCNA, MCSA and Kaspersky certifications. That background shapes how I design custody, secrets management and production boundaries.
