Netherlands, building in public

Apps, agents, and the infrastructure they run on.

Principal Engineer and Microsoft Certified Trainer. I ship SaaS at Spot Suite, run a fleet of AI models, and keep an always-on agent on call.

Apps I build and run.

B2B SaaS on Cloudflare Workers, one product per customer environment, marketplace billing, and provisioning that stands a tenant up end to end.

Platform

Spot Suite

The umbrella for my product line: shared design system, per-customer infrastructure, Stripe and cloud-marketplace billing, and a provisioner that turns a purchase into a running tenant.

File transfer

xEvolve

Secure file transfer for teams replacing legacy MOVEit setups. SSO, per-tenant storage, full audit trail.

Open source.

Tooling from the daily workflow, published as it stabilizes.

Go

no-mistakes

A push gate. git push no-mistakes runs review, lint, and tests before anything lands on a branch.

GitHub ↗
TypeScript

mcp-offload-router

Self-hosted MCP server that routes heavy agent work to flat-rate model subscriptions instead of burning frontier tokens.

TypeScript

agent-office

Watch Codex, Claude, OpenCode, and Antigravity work side by side in a shared browser office.

GitHub ↗
Python

hermes-agent

My fork of NousResearch's agent framework, the core of Hermes below. I contribute back upstream.

GitHub ↗
Rust

mw5-remap

Visual joystick binding editor for MechWarrior 5. Because sim rigs deserve good tooling too.

Benchmarks

Agent benchmarks

Public, reproducible races between coding agents: one prompt, real cost, real wall-clock, video receipts.

The model fleet.

Fifteen-plus providers, because I actually run them. Grouped by where they live and what they are trusted with.

Frontier, daily drivers

Claude Fable 5 / Opus 4.8
Conductor of the fleet. Architecture, judgement, review, final say.
GPT-5.5 (Codex CLI)
Large refactors with long briefs, multi-agent runs.
Grok 4.5 / Grok Heavy
Live X search, image generation, and parallel worker subagents.
Cursor
Second-opinion implementation lane.

Flat-rate coding fleet

Kimi K2.7 Code
Long-horizon agentic implementation, 256k context.
GLM-5.2
Bulk codegen and whole-repo analysis at 1M context.
MiniMax M3
Batch text work, summaries, light codegen.
Qwen 3.6 / GPT-OSS-120B / Nemotron
Review lanes and second opinions on a fixed-price pool.

Serverless and edge

Mistral Large 2411
The brain of the Hermes agent, on a flat-rate endpoint.
Cloudflare Workers AI
Answers product chat at the edge when I am offline.
NanoGPT pool
Per-bot model pools for a fleet of Discord personas.

Local, own hardware

Qwen 2.5 / Gemma (Ollama)
Small weights on my own GPUs for offline and private quick work.

The honest split: small models run at home, the heavy lifting rents its GPUs by the subscription.

An agent that never sleeps.

Hermes is my always-on agent. It runs around the clock on two boxes, a repurposed gaming laptop at home and a small VM in a datacenter, and I talk to it over Telegram from wherever I am.

It watches CI, fixes deploys, triages GitHub issues, sends me reports, and posts to my own dashboards behind Cloudflare Access. Its brain is swappable: it started on Grok, runs on Mistral Large today, and keeps Grok wired in for X search and image generation.

The open-source core is NousResearch's hermes-agent, and I contribute back upstream.
