How I can help

Services

Four offerings. Fixed scope, direct comms, code that keeps working after I leave.

01

AI Integration Sprint

For B2B SaaS teams running in production that want to ship an AI feature — semantic search, content generation, automated classification or an agent for an internal workflow. Delivery: feature in production with observability, automated evals and inference cost under control.

Duration
6 weeks
02

AI Product MVP

For technical founders or teams building a new product with AI at the core. I act as your interim founding engineer — discovery, architecture, full-stack build (frontend, backend, AI, infra), deploy and 30 days of support, with handover docs for the next developer.

Duration
10 weeks
03

Tech Lead Fracionado

For Seed–A startups with 2–3 junior devs that need senior leadership without a full-time hire. 40–60h/month on architecture, code review, critical decisions and tech roadmap, with team mentorship and leadership on AI, observability and scaling decisions.

Duration
3 months minimum
