Built by someone who needed it.

I built Tech Abstractions because I kept running into the same gap in every resource I found: they teach you what tools exist, but not how to reason about using them.

You can watch 10 hours of MLOps content and still not know whether your team should build a feature store. You can learn the standard system design template and still freeze when the interviewer moves past it and asks you to defend a tradeoff you haven't thought through.

That second half of the interview is what this site is for: the follow-up questions, the bottlenecks, the tradeoffs and the decisions. The practice questions put you in a production scenario and ask you to write your own answer, then compare it with how an experienced engineer would reason about it.

What's here now: the MLOps Production Guide, the practice question bank, and early chapters on agentic AI. Every chapter is free to read; Pro adds the workbook exercises, every expert answer and feedback on your practice answers.
