About Me

Hello there, I'm Attaphong. You can also call me "Ohm", my nickname. I'm a software engineer who loves building scalable products. I enjoy technical planning, system architecture design, and performance and cost optimization.

These days I'm a Staff Software Engineer at Agoda, driving flights connectivity.

My Experiences

  • Maintained and enhanced the core metadata services (millions+ QPS) at TikTok, serving millions of users globally.
  • Built a robo-advisor and trading platform from scratch for Finnomena, now a Series-B-funded fintech startup managing over USD 1 billion in assets.
  • Built the Progressive Profiling framework for Kimberly-Clark Corporation North America, used on the Huggies and Pull-Ups sites.
  • Founded my own B2B fintech startup (cashflow management with yield optimization for corporates) which won a national startup competition. It eventually folded, but I learned a great deal along the way.
