Dr.T — AI Systems Architect

Machine Learning Infrastructure · Distributed Systems · Data Engineering · Algorithmic Engineering

I design and build intelligent systems where machine learning, distributed computing, algorithms, and production infrastructure converge.

My focus is not isolated model development. I engineer complete systems that must operate under real-world constraints involving scale, latency, reliability, observability, security, and cost.
