From schematic to production.

A full-stack hardware engineering offering, covering every step from initial component selection to factory hand-off... and the occasional non-hardware side-quest.

[01]

Circuit design

  • Parts selection based on your constraints : existing stock, availability, price, preferred vendors and any other criteria you need to honour.
  • Specialized in mixed-signal boards, IoT and embedded systems (STM32, ESP32, RP2350…), system-on-module carriers (Raspberry Pi Compute Modules, Allwinner-based SoCs), inter-IC communication (I²C, SPI, I²S, UART, GPIO…) and industry-specific I/O — analog audio in/out, IO-Link, RS485 / DMX, Ethernet, WiFi and sub-GHz radio modules.
  • Industrial constraints, shielding, environmental parameters, RF environment, specific operating voltages, and electrostatic discharge (ESD) protection.

Schematic capture & PCB layout

  • ECAD tools: KiCAD 10, Altium Designer.
  • Creation of custom component libraries.
  • Multilayer PCBs with high-speed length-matched differential buses, sensitive analog signals, and impedance-controlled traces.
  • Size and shape mandated by the enclosure, with extra care for mechanical constraints: connector placement, assembly clearance, UI elements (displays, LEDs, buttons, encoders) and board fastening techniques chosen for ease of manufacturing, shortest assembly time, all tuned to match your production batch size.
  • Electromagnetic compatibility & interference (EMC / EMI) considered from the very start of the project, maximizing your chances for applicable compliance tests to pass.
  • Careful placement and routing of high-efficiency switching DC regulators, minimizing EMI emissions and optimizing power distribution to critical components.
  • Test points, debug interfaces, UART / JTAG / SWD programming ports and status LEDs — built in, not bolted on.
  • Board-to-board and wire-to-board connectors for modular multi-board systems (standard FPC, JST, Molex) - accounting for signal integrity, current carrying capability, derating, assembly error prevention and vibration resistance.
  • Drawing and specification of custom cable assemblies and wire harnesses.
  • Maintenance of documentation including notable design decisions, calculations, simulations and agreed-upon engineering trade-offs.

Custom enclosures

  • Advice on suitable enclosures for your targeted production price point, durability, mounting, environmental and flammability requirements.
  • Conception and 2D / 3D drawing of CNC, sheet metal, machined and extruded parts.
  • Customization of off-the-shelf boxes from common enclosure manufacturers, or designing of fully custom models for specific needs.
  • 3D printing of small parts — translucent light pipes, button hoods, brackets, in particular for small batches where injection molding isn't an option.
  • Specification of material, surface finish and printing.
  • Manufacturing vendor RFQ, selection, technical briefing, production files and follow-up.
  • Export of 2D dimensional drawings in PDF, DXF, SVG, 3D models in STP, STL and any other format needed for production, documentation and archival.
  • CAD software: Autodesk Fusion.
[04]

Prototype & production

  • Exporting of production files: Gerbers, Bill Of Materials, pick & place position files, mechanical files, assembly instructions.
  • Communication with factories: PCB/PCBA fab houses, enclosure manufacturers, various vendors of cables, front panels...
  • Custom test jigs (PCBs, pogo pins, clamping fixtures) and associated test scripts.
  • Board bring-up: verification, smoke test, thermal imaging, fire extinguisher 🧯, fire brigade debrief, measurements, test firmware, peripheral IC communication tests and drivers.
  • Sync-up with assembly personnel to gather their feedback, find solutions to time-consuming and difficult steps, and improve the next iterations.
  • Most proficient languages: C, Python.
// Other freelance services

Non-hardware specialties.

A handful of other things I do professionally, usually for clients in the event industry.

Laser safety officer

Certified Laser Safety Officer for the event industry — laser light show safety assessment and compliance documentation, in accordance with IEC TR 60825-3.

Lighting designer

Light show programming and operation: Find me professionally pushing buttons on my ChamSys MQ70, abusing MADRIX 5's scripting engine for beat-synced interactive LED art, sending questionable content on LED screens with Resolume Arena and designing stages and lighting plots with Capture 2026 Symphony.

DJ

Guess what type of music I occasionally DJ? That's right... electronic music.

Personal centers of interest when I'm not in front of KiCAD / Fusion: homelab, smart home, cyber (in)security.
