## Services

- **AI enablement for teams**: Practices that make a team measurably faster, and keep working after the novelty wears off. Delivered: A working assessment of how your team builds today, agentic workflows set up in your own repositories, an SDLC adapted for AI-assisted delivery, and a documented practice your engineers keep using after I leave.
- **Technology counsel**: A senior read before a decision that is expensive to reverse. Delivered: A focused review of the decision in front of you, whether that is architecture, build versus buy, or how to staff the work, closing with a written recommendation and the reasoning behind it.
- **Custom development**: Scoped builds held to the standard of platforms with millions of monthly users. Delivered: Discovery and scope in writing, the build itself, and a handover with documentation and tests your team can run without me.
- **Performance engineering**: Making a product people already use measurably faster, and keeping it that way. Delivered: Measurement of what your users actually experience, a prioritized list of fixes with owners and expected impact, and the first round of them implemented alongside your team.
- **LLM systems and assistants**: Assistants, chatbots and retrieval systems built on your own data, held to production standards rather than demo standards. Delivered: An assistant or chatbot built on your own data, retrieval and evaluation set up so answers stay accurate and cite their sources, and the infrastructure to run it in production.
- **Mentoring**: For engineers in Latin America working toward international roles. Delivered: Regular one-to-one sessions, interview practice from someone who runs the other side of the table, and honest feedback on how your experience reads abroad.
