I work across the full automation stack — from field devices and firmware up to DCS/SCADA and the software that ties it together. Lately that means gas detection systems by day and an over-engineered home lab by night.

About

What I actually spend my time on

Three things keep showing up in every role — the field-to-supervisory stack, the conversation between engineering and the people paying for it, and building the tools that make the next project faster.

01 — CONTROLS & AUTOMATION

Full-stack automation

Deep hands-on experience across DCS/SCADA architecture, machine control software, gas detection systems, and Industry 4.0 integration — comfortable from the field device up to the supervisory layer.

02 — TECHNICAL CONSULTANT

Engineering ↔ business

Presenting complex control system architectures to customers, supporting pre/post-sales, and translating technical requirements into accurate, competitive proposals.

03 — PRODUCT DEVELOPMENT

Concept to field

Actively involved in New Product Initiatives from concept through deployment — contributing to roadmaps, building internal automation tools, and writing implementation standards.

The Lab

Where the magic happens

A seriously over-built work-from-home setup: ArkhamOne (the mainframe), a Proxmox cluster, a solder station that sees more action than the kitchen stove, and enough SBCs to worry my electric bill.
