You will get Roadmap call: The technical spine to scale your business to 7-figs.
Project details
Stop wasting $50k on AI prototypes that hallucinate in production. Most businesses build "toys"; I architect high-margin assets designed for $100k/mo scale.
The ROI of Elite Engineering:
Scale or Fail: I use First Principles to build the technical spine of your business. This isn't just a chatbot; it's a production-grade autonomous engine built for millions in ARR.
Sequoia-Vetted Logic: I’ve engineered AI for $80B public companies (Nubank) and a $350M unicorn (ENTER). I bring that level of enterprise-grade reliability to your specific workflow.
The "Brazilian MIT" Rigor: With an M.S. from ITA, I solve the edge cases that break 99% of other AI projects.
The Offer: Book a call to identify the manual bottleneck draining your margin. You’ll leave with a custom 24-hour roadmap and a detailed Technical Blueprint to automate your operations.

𝗜 𝗯𝘂𝗶𝗹𝗱 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻-𝗴𝗿𝗮𝗱𝗲, 𝗮𝘂𝘁𝗼𝗻𝗼𝗺𝗼𝘂𝘀 𝘀𝘆𝘀𝘁𝗲𝗺𝘀 𝘁𝗵𝗮𝘁 𝘀𝗰𝗮𝗹𝗲. I specialize in White-Collar Automation: transforming complex, high-stakes human workflows into high-margin AI engines that move the needle for your business.
PROVEN TRACK RECORD
- From $0 to $225k/mo in 10 Months: As Founder and CTO at Jumpstart, I built the AI legal engine that manages US immigration petitions end-to-end. I replaced manual labor with high-precision autonomous agents that handle high-stakes legal logic.
- The "Sequoia & Founders Fund" Filter: As Founding Engineer at ENTER (Enterprise AI), I helped scale the company to a $350M valuation with $40M+ in funding from Sequoia Capital and Founders Fund. I personally engineered the AI solutions used to close enterprise giants like Nubank (publicly traded, $80B+ market cap).
- ML at Scale for a $3B Unicorn: As Data Scientist at Wildlife Studios (backed by Benchmark), I built ML pipelines processing terabytes of data and delivered a pricing model that generated +15% expected profit (~$45k/month additional) while maintaining ROAS.
PREMIUM ACADEMIC BACKGROUND
- Double ITA Alum: I hold both a Bachelor's and a Master's in Computer Engineering from ITA (the "Brazilian MIT"), specializing in Large Language Models (LLMs).
- Elite Problem Solver: Multi-medalist in National Math, Physics, and Chemistry Olympiads. I bring a rigorous, first-principles approach to architectural challenges that require complex logical reasoning.

WHY MOST AI PROJECTS FAIL (AND WHY MINE DO NOT)
I operate as your Technical Partner, not just a dev.
1. Weekly Loom Videos: Every Friday, you receive a video walkthrough of exactly what was built and what is coming next. No guessing, no ghosting.
2. Notion Project HQ: 24/7 access to a central "Source of Truth" containing all project requirements, specs, and a history of every update.
3. No-BS Consulting: I provide honest advice in your interest, even if it means telling you a project is not worth building.
THE METHOD: SKATEBOARD TO SUPERCAR
- The Skateboard: A functional, "thin-slice" MVP in 2 weeks to prove core value.
- The Motorcycle: Scaling orchestration, hardening security, and adding robust evals.
- The Supercar: A high-performance, autonomous system with 99.9% reliability.
