Acerca

Senior Android engineer, 5+ years shipping native mobile products (Kotlin, Jetpack Compose, MVVM/Clean Architecture). Since late 2025 I've been building agentic AI systems — LangGraph orchestration, RAG, multi-agent flows, FastAPI backends — and running them in production on my own infrastructure. Most of what I write here comes from things that broke.

Experiencia

  1. AI Engineer — Tec5

    Apr 2026 – Present Remote

    Build AI and automation systems for SMBs — the segment where an agent has to work reliably on a small budget, without an ML team behind it. LangGraph for orchestration, FastAPI for the service layer, RAG over Postgres with pgvector, and n8n for the integration surface. The constraint that shapes every decision: it has to keep running when nobody's watching it.

  2. AI Agent Architect — Freelance

    Oct 2025 – Present Remote

    LangGraph orchestration and multi-agent systems: cyclic state machines, long-term memory and checkpointing, human-in-the-loop approval gates. Trace auditing and prompt versioning with LangSmith. FastAPI backends connecting agent logic to mobile and web clients.

  3. Senior Android & AI Engineer — AGOS

    Jan 2025 – Apr 2026 US (Remote)

    Native Android (Kotlin, Jetpack Compose, MVVM, Room, REST). Led the integration of generative AI into the mobile stack — agentic flows for UX and internal data processing.
