Production LLM systems, and the evaluation that shows whether they work.

Leading PadelGPT at PadelOS: a multi-agent LLM system for players and club staff, shipped as 33 versioned releases in six weeks and evaluated on 1,280 real support threads.

The road here ran through product management for an IoT supply-chain platform in Saudi Arabia, three startups, and three years of consulting in process engineering, ERP and financial modelling.

PadelGPT, as built

A multi-agent system serving players and club staff inside PadelOS's white-label club apps. The design decisions below are the ones a reviewer would argue with.

Agents and tools

  • 15 LangGraph agents: two supervisors routing to 13 specialists, one supervisor per surface (player, admin).
  • 169 tools (102 admin and 67 player) on two FastMCP servers, reached in-process and over HTTP for white-label consumers.
  • Specialists are read-only and hold no product knowledge; knowledge search and escalation live on the supervisor alone, so a specialist cannot shortcut its own domain.

Safety boundaries

  • Tenancy is enforced server-side: identity parameters are stripped from the schema the model sees and injected at call time.
  • Mutating player tools are disabled inside the agent; its one deliberate write is escalating to human support, with the conversation's details attached.
  • Boundaries are pinned by tests that assert on the resolved system prompt the model actually receives, not on configuration that says it should.

Data and retrieval

  • Text-to-SQL as a bounded, deterministic LangGraph StateGraph on o3 and o4-mini, against a read-only replica.
  • Audience segmentation on top of it, with a controlled-vocabulary ontology and a classifier that refuses discriminatory targeting.
  • FAISS inner-product index over normalised embeddings, swapped atomically on rebuild.

Delivery

  • 33 versioned releases in six weeks through a four-stage promotion chain.
  • API call sequences described in Arazzo, because the API’s primary readers are AI coding agents, not people: an offline drift gate in CI, and a live flow gate after each deploy to staging, release and prod.
  • Authored 601 of 818 commits in the repository.

What clubs adopted

Over one quarter the two admin surfaces were measured against each other. Segment use grew 7× to 40% of admin messages while costing 6.3% of admin model spend.

Clubs had adopted the efficient surface, so the roadmap moved onto it: widening segments from building campaign audiences into answering open analytics questions about the club.

How we measure

  • Measured and estimated are kept apart, and every figure says which it is.
  • When two methods disagree, report the range, not the better number.
  • An automated judge has to agree with a person before any of its numbers are published.
  • Estimates carry their assumptions beside them, so a reader can redo the sum.

Career

Jan 2024 – present

PadelOS

Software that padel clubs use to run bookings, payments and their player app. Based in Amsterdam.

Building h9k

Oct 2026 – present

h9k is a new product at Moonlabor, the company PadelOS was spun out of. It is in early development.

  • The idea in one line: ask your colleague's AI agent instead of interrupting them.

Applied AI Lead, PadelGPT

Jan 2025 – present

PadelGPT is the AI assistant inside PadelOS. It answers players in their own language, at any hour, from each club's live bookings, prices and rules.

  • 15 LangGraph agents — two supervisors routing to 13 specialists — behind a player surface and an admin surface, calling 169 tools (102 admin and 67 player) on two FastMCP servers, reached in-process and over HTTP for white-label consumers.
  • Tenancy enforced server-side: identity parameters are stripped from every tool schema the model sees and injected at call time from server-set configuration, so a prompt cannot widen its own scope.
  • Text-to-SQL as a bounded, deterministic LangGraph StateGraph — validate, select tables, select columns, write, execute, review, at most three loops — on o3 and o4-mini against a read-only replica. It powers audience segmentation, with a controlled-vocabulary ontology and a classifier that refuses discriminatory targeting.
  • Retrieval over the club knowledge base on a FAISS inner-product index of normalised embeddings, rebuilt by temp-file-then-rename so a live server never reads a half-written index.
  • Measured the two admin surfaces against each other over a quarter: segment use grew 7× to 40% of admin messages at 6.3% of admin model spend. The efficient surface was the one clubs adopted, so the roadmap moved onto it.
  • 33 versioned releases in six weeks, promoted main → staging → release → prod. Authored 601 of 818 commits in the repository.

Product Manager, Pollen

Jan 2024 – Jan 2025

Pollen tracked food from farm to shop in Saudi Arabia, so supply problems and spoilage could be caught early. It was built at Moonlabor, the company PadelOS was later spun out of.

  • Device-agnostic IoT ingest: Teltonika, BiTrek and Digital Matter trackers on roaming IoT SIMs, with data arriving over MQTT through a webhook or by polling, queued, and consumed in chunks.
  • Simulacrum, an IoT fleet simulator: continuous-monitoring and inter- and intra-city travel modes, a configurable fleet and routes, and route choice mined from real logistics data, so models could be tested against realistic streams around the clock.
  • Anomaly triage with a human in the loop: the system flags and ranks supply-chain anomalies and recommends an action; the decision stays with a person.
  • Platform: NestJS microservices on AWS EKS, React, PostgreSQL, Redis, RabbitMQ, the ELK stack and CloudWatch.
