Guilherme Latrova

Senior Full-Stack Engineer · AI-First

I build products that ship. A decade of Python in production, from real-time kitchen systems to security platforms crunching terabytes, and today I build AI-first systems end to end: LLM pipelines and agents with tool calling, background jobs, retries and idempotency. I work AI-first, with coding agents as my default.

    AI Engineer & Founder

    Independent AI ProductsGenerative AI

    • Launched two AI video products solo: dayvid.ai and Vibe Videos.
    • Orchestrated multi-model LLM pipelines with fallbacks and schema-enforced outputs.
    • Built LLM evals: blind A/B across models plus multimodal QA before render.
    • Made renders 11x faster and 19% cheaper by benchmarking GPU vs Lambda.
    • Cut projected AI cost per video ~10x ($15 → $1.50) via per-stage token analysis.
    • Shipped an OAuth 2.1 MCP server and a tool-calling agent that edits videos.
    • Built personal AI agents (Claude Code + MCP) automating email, invoicing and publishing.
    • 8,000+ commits in 8 months driving parallel Claude Code and Codex agents via Orca, kept production-grade by custom skills, AI code review and thousands of tests.

    • Cut CI test time 60% (12 → 5 min) by parallelizing pytest on GitHub Actions.
    • Data snapshots cut customer bug reproduction from 3 days to hours.
    • Incremental sync over terabytes cut dashboard lag from 48h to 3h.
    • Routed alerts to the owning engineer via structured logging, reducing MTTR.
    • Built AI-assisted incident triage: a Claude Code workflow that analyzes sync failures across 8 production regions and recommends fixes.
