About

My journey started in 1999, when I was thirteen, with a 486 DX2 running DOS. There was no internet at home, only a few pages of handwritten notes from my uncle on how to find my way around the machine. Figuring things out from those notes was the start of a long road.

That road ran through software support, then hardware and network support, then programming: first C++, then C#. I took on small freelance projects, then went to university to study software engineering the academic way, at Islamic Azad University. In 2010 I joined Saze Gostar Saipa as a software and network contractor, and then spent about ten years building and supporting websites, internal applications and software for different companies, as part of small teams: learning management, payroll, CRM and office automation.

From 2020 I moved into engineering roles on larger distributed systems: railway operations and ticketing, then an English-learning platform built on Spring Boot microservices, gRPC and Kafka, running on AWS infrastructure I wrote in Pulumi to stay within a fixed budget. Most recently, as solution architect and .NET lead, I designed a multi-tenant e-invoicing platform and wrote its phased delivery plan.

What each step taught me: quality lives in the details, a plan only matters if it is kept, and a team does its best work when someone clears the path. On the side I build AI systems (multi-agent trading, natural-language BI, and RAG assistants that cite their sources), because I still enjoy learning something new.
