I build custom software and web applications that fit your process exactly — by one engineer with 9 years of experience, backed by a solid background in industrial automation.
Focus & background
I build custom software for all kinds of processes — backed by solid experience in industrial automation that I bring to the table.
Less manual work, fewer copy errors and a grip on your data — applications that do exactly what your process needs, where off-the-shelf packages fall short.
Years of experience with control and visualisation of machines and processes — knowledge I bring to every software project.
Why Haan
Extensive experience as a software engineer across industrial and business projects.
At home on both major platforms — I choose what fits, not just what I happen to know.
Two disciplines in one pair of hands — control and application fit together seamlessly.
No big agency, no layers in between. You work directly with the engineer.
Featured work
A multi-tenant SaaS platform that gives new employees a personal, role-based onboarding journey instead of one generic handbook. An assembly engine composes the journey automatically from reusable modules (document, flowchart, checklist, video, quiz…) based on role and department; with version-bound sign-off for compliance, HR reporting, per-tenant branding and NL/EN. The live demo logs you in automatically and resets every hour.
A complete replacement of an ageing Excel/Access system for an engineering department. Engineers, tasks and projects in one overview — with automatic capacity calculation, drag-and-drop scheduling, critical-path analysis and reports. Python backend + React frontend packaged as a single Windows installer.
View the projectAn AI layer on top of time-series and tabular data: you ask a question in plain language and get an answer plus the right chart back — no query language required. A language model of your choice (Claude or open models) translates your question into a safe, read-only query through tool use — across multiple data sources, from CSVs to industrial time-series in InfluxDB. The live demo runs 24/7 on demo data.
A simulated industrial batch tank with real control, entirely in the browser: two PID loops, a batch sequence and a SCADA-style HMI. Play with setpoints, run a batch and inject faults — and watch the control system react live. The same tags feed the chain over OPC UA: simulate → collect (EdgeForge) → analyse (InsightForge). The live demo runs 24/7.
A self-built platform that collects real-time data from machines (OPC UA, S7-1500, Modbus, MQTT and more), stores it safely and shows it in live dashboards — with crash-safe storage against data loss. The live demo runs 24/7 on a simulated bottling line.
An ML layer on top of the OT data EdgeForge collects: robust anomaly detection, forecasting with a time-to-threshold and one explainable health score per asset. The closing piece of the chain — simulate (TwinForge) → collect (EdgeForge) → analyse (SignalForge). The live demo runs 24/7 on the real EdgeForge data.
How I work
A clear route in four steps — so you always know where things stand.
We discuss the problem, the context and the constraints. I ask the questions that matter.
A clear approach, timeline and price. No surprises afterwards.
I build, test and keep you informed. There's always room to adjust along the way.
Delivery, testing and handover — so you can get started right away. Aftercare included.
