Who is Samuel as an engineer?
I’ve always been interested in understanding how software work and then figuring out how to make them work better.
My journey has taken me from backend and distributed systems to AI, robotics, NLP research, and full-stack product development. Those experiences have taught me to look beyond the code: to understand the problem, question assumptions, and design systems with reliability, simplicity, and real-world constraints in mind.
This page is a little less about the technologies I use, and more about the experiences and ideas that have shaped the engineer I am today.
Engineering principles that guide how I build
- Understand the problem first
- Prefer simple solutions
- Design for failure
- Make systems observable
- Learn by building
