Frequently Asked Questions
Common questions about working together, courses, and what to expect.
I help people figure out if and how AI can solve their problem, then I build the solution and ship it to production. That could be a full application, an agentic system, an automation workflow, or a strategy session to map out what's possible. Every project is different because every problem is different.
It starts with a conversation. You tell me the problem, I ask questions, and we figure out if there's a fit. From there I send a plain-language proposal with scope, cost, and timeline. Engagements range from a focused audit (1-2 weeks) to ongoing embedded work (3-6 months). You see progress every week.
No. I've worked across healthcare, legal, real estate, retail, and SaaS. The common thread isn't industry knowledge, it's the ability to walk into unfamiliar territory, learn what matters, and build a real system. That's the skill.
AI Readiness Audit: $3,500 fixed price (7-day engagement, you get a clear roadmap of what to build and why). Strategy Session: $300 (60 minutes, fully credited toward a larger project). Longer projects are quoted monthly based on scope, so contact me for a range. I show prices because transparency builds trust and saves both of us time.
Yes, all courses are free to access. Some advanced lessons are marked as Pro content. These require a Pro membership for full access, but every course includes free preview lessons so you can evaluate the content before committing.
Free access gives you the complete curriculum for foundational courses and preview lessons for all courses. Pro includes every lesson across all courses, including advanced production-focused content, code examples, and exercises.
It depends on the course. Foundations-level courses like 'What AI Actually Is' and 'AI Strategy for Business' require zero coding. Intermediate and Advanced courses assume you can read JavaScript/TypeScript and are comfortable with APIs.
Courses range from 1 to 4 hours of content. Each lesson is 10-25 minutes. You can go at your own pace. There are no deadlines or live sessions.
I am a Senior Software Engineer specializing in agentic AI systems and product engineering, based in Miami Beach, originally from Venezuela. I explore unfamiliar problems and ship production systems. My focus areas are RAG pipelines, LLM evaluation, voice and chat agents, agentic systems, cost optimization, and production AI architecture. I also teach what I learn through free courses and writing.
