About
I'm Steven W. White. This site is named for Key Largo—the first island on A1A, and where many of my journeys begin.
Somewhere between the noise and the sea, there's a place where the thinking clears. No deadlines pressing. No meetings waiting. Just the opportunity in front of me and the time to think it through. I write from that place whenever I can find it.

25 years building things—first telecom networks, then neural networks. In 2009, I founded ImageVision, a computer vision company building image recognition and content moderation for social platforms. We raised $12.5M, landed contracts with Google, Facebook, Apple, Samsung, and In-Q-Tel, and built systems processing billions of images. Two Hat Security acquired us in 2019, and Microsoft acquired Two Hat in 2021. That technology now helps moderate Xbox, Minecraft, and MSN.
After the exit, I joined NVIDIA as a Deep Learning Solution Architect—TensorRT optimization, edge inference, industrial IoT. Then AWS in 2019, where I've worked as an AI/ML Solution Architect and now build security AI systems with multi-agent architectures.
Two decades of lessons:
- Demos and deployment are different planets
- The model is 10% of the work
- Latency budgets teach you what matters
- Ship it, then improve it
What's Here
These tutorials are what I wish someone had handed me when I started. Every one has complete, runnable code—if you can't run it and learn from the output, I haven't done my job.
- Embeddings — Bi-encoders, cross-encoders, semantic search
- Retrieval Systems — RAG, ranking, vector search
- Agents — Tool use, orchestration, real-world APIs
Background
- M.S. Data Science — University of Texas at Austin
- B.S. Computer Science — University of Texas at Dallas
- 2 patents in computer vision and machine learning

By day, I work at AWS. This site reflects my personal views and projects, not those of my employer.
