What I do

Hola! I'm Royal

A full-stack AI developer with 3+ years shipping production multi-agent systems, end to end: the agents, the backend they run on, and the interface.

AI & Agents

Production LLM and multi-agent systems: supervisor-swarm orchestration with LangGraph, A2A and MCP, prompt engineering, LLM evaluation with Langfuse, vector search.

    AI Engineer

    I co-own the core AI service: the multi-agent brain behind Zensible's Slack and Teams conversations.

    what I'm building there ↓
    • Runs on FastAPI, PostgreSQL and LangGraph, streaming multi-agent conversations with every customer's data isolated in the database. Halved database work per agent call: 58→29 SQL statements, 122→45 ms.
    • Architected two-tier supervisor-swarm orchestration: agents hand off to peers, run in parallel with asyncio, and can't loop forever.
    • Built directives end to end: admins drop a request into someone's live chat as a parallel conversation with its own memory, without derailing what they were talking about.
    • Moved prompts, tools, personas, guardrails and agent structure into the database, so behaviour changes need no engineer or deploy. Config now updates instantly instead of taking up to an hour, and two paid services got retired.
    • People start company workflows like leave and provisioning straight from chat; a one-shot tool makes sure each is filed exactly once.
    • Built for scale: Redis atomic locks that fail open, background queues for long agent runs, size-bounded caches, and zero-retry execution so no model call is ever paid for twice.
    • Wrote the team's engineering and ticket-sizing guidelines and its layered service architecture, and led a 225+ file static-analysis cleanup.
