👋 Well Hello There! ✨

I’m Selenge Tulga , I’m a Data Engineer with 7 years (4.5 DE + 2.5 SWE) of experience and a background in Computer Science (B.S.) and Data Science (M.S.). I focus on building reliable, production-grade data platforms that replace manual reporting and support finance, operations, and business decision-making.

I enjoy working at the intersection of data systems, analytics, and real-world constraints, with a strong emphasis on data correctness, observability, and long-term maintainability. I care less about flashy tools and more about systems that are easy to reason about and trust.

📍 Based in Austin, TX 🇺🇸
