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

- Built a robo-advisor and trading platform from scratch for Finnomena, which is now a Series-B-funded fintech startup managing over 1 billion USD in assets.
- Built the Progressive Profiling framework for Kimberly-Clark Corporation North America, used on Huggies and Pull-Ups sites.
