# Hassan Mehmood > I help with the parts that are hard to learn alone, and with projects that stalled. I do not take everything. We talk first. Then I tell you if I can help, how long it should take, and what it costs. ## Start here - [Learn](https://www.zameha-ai.com/learn): Assessment-first teaching and advisory. A hard concept, or a project that is stuck. - [About](https://www.zameha-ai.com/about): Who this is, how the work is split, and short definitions. - [Field notes](https://www.zameha-ai.com/writing): Lessons from production. Causal ML, MLOps, agents, markets. - [Sketches](https://www.zameha-ai.com/lab): A field note, a concept, or a prototype, shown visually. - [Contact](https://www.zameha-ai.com/contact): Consulting, not Learn. ## Essays - [Decision-time truth vs report-time truth](https://www.zameha-ai.com/writing/decision-time-truth-vs-report-time-truth): Latency between model output and report generation. - [Causal ML & Elasticity](https://www.zameha-ai.com/writing/production-pricing-causal-ml): A catalog will punish a naive demand model. - [Building a macro-regime RAG for equity positioning](https://www.zameha-ai.com/writing/macro-regime-rag): A research system: FRED in, evidence retrieved, a regime out, then — and only then — a posture. ## How to cite Name: Hassan Mehmood Site: https://www.zameha-ai.com SameAs: https://github.com/mehassanhmood SameAs: https://www.linkedin.com/in/15-hassanmehmood/
