01 Flagship · AI agents

Agent systems that use your APIs, documents, and real business context.

Multi-agent platforms, RAG pipelines, streaming interfaces, and tool integrations for teams that need answers and actions inside production workflows.

Coordinator agents and nested teams
Retrieval over private documents
Tool calls against internal APIs
Streaming UI and session restoration

02· payments & platforms

Payment flows and platform services that survive edge cases.

Bespoke pre-authorisation, provider integrations, service boundaries, and operational APIs where failure modes matter.

PayGate and provider integration
Microservices around legacy cores
OCPP and OCPI integration

03· apps & interfaces

Frontends people can use all day.

Mobile apps, web dashboards, embedded product components, and operator screens with streaming state and sensible recovery.

Expo · Vue · Next.js · Svelte
Advanced streaming components
Design systems and product UI

04· anomaly systems

Models that catch problems before support tickets do.

Statistical detection, computer vision pipelines, VLM analysis, and LLM reporting wired into existing queues and background jobs.

YOLO meter detection pipelines
Leak and usage anomaly detection
Event queues and task runners

05· documents & automation

Professional work products generated from code.

Agent-assisted legal and operational document workflows where users stay in control and templates compile to production-grade output.

Rust product cores
Typst document templates
Human-directed coding agents

Production systems in the wild.

// 03 · client work

client · charge · mobility infrastructure

Yhat gives us the kind of senior product engineering that can hold payments, mobile UX, and charging infrastructure in one head. The work lands cleanly, even where the edge cases are ugly.

Expo client app
PayGate incremental pre-authorisation microservice
CSMS integration work across OCPP and OCPI

client · weconnectu · property software

The AI platform has become a real product surface, not a demo. It connects to our tools, streams complex agent work clearly, and gives property managers useful insight inside the workflows they already use.

Full-stack AI framework
Nested multi-agent workflows and RAG
Advanced Vue streaming component with session restoration

client · urbtec · utility management

Yhat turned difficult meter data into actionable signals. Image recognition, anomaly detection, and generated reporting now plug into the operational system without forcing us to rebuild the core.

Custom YOLO meter detection
Realtime leak and usage anomaly analysis
LLM and VLM reporting through background queues

beta product Praxis · legal workflows

Coding agents for lawyers who still want to drive.

Praxis is a Rust-based legal workflow product that lets lawyers work with coding agents to produce structured legal documents. Templates are generated through Typst, so agents can author precise PDFs while the lawyer directs the work.

active beta user Johan van Heerden

Uses it all day, every day. The working model has changed completely.

The stack is broad. The taste is narrow.

Scope

A fast technical brief. We identify the system boundary, risks, weird integrations, and what is worth building.

Prototype

Working code early. Deployed somewhere you can click, inspect, and route through real data.

Ship

Pull requests, production telemetry, release notes, and integration with the people already carrying the system.

Hand off

Clean code, documentation engineers will read, and support while the system settles.

-> 06 · let us talk

You have the operational problem. We can probably build the system.

Tell us what you are building, what it has to connect to, and what happens if it fails. We will tell you if we can help, what it costs, and when it ships.
