~ the short version of Yamin's career ~

Summary

I'm a senior full-stack engineer with over 13 years of experience building and shipping web and mobile products, from telecom systems used by tens of millions of people to B2B trading platforms.

I lead backend work in Node.js, Python (FastAPI) and Java, build frontends in React, Angular and Vue, and I enjoy mentoring teams and working closely with the people who use the product.

Highlights

  • Led the architecture of a customer management system for a mobile operator, scaling to nearly 70 million subscribers.
  • Led and mentored a team of 6 engineers through a full project lifecycle.
  • Built a reusable CMS that cut delivery time by two months and helped grow company revenue 140% in a year.
  • Revived a stalled project and launched its backend in under 2 months.
  • Cut mobile app load time by 80% with a new caching system, and by 40% in later Flutter and Vue work.
  • Used AI (OpenAI and Gemini APIs) to cut manual product-data editing and search time by 40%.
