Electronics and board design
Worked across the hardware lifecycle of 7+ IoT and automation devices. Designed mixed-signal and high-speed PCBs using Altium and Eagle, with board complexity ranging from two to six layers.
Kasper smart home.
From PCB to product.
Electronics, embedded firmware and mechanical integration for connected-home devices, alongside progression into technical leadership.
01 / OVERVIEW
At Kasper, I grew from Electronics Engineer to Senior Electronics Engineer and then Chief Electronics Engineer while staying close to the hardware.

Simplified conceptual overview of the work, not an implementation schematic.
02 / THE CHALLENGE
Where the engineering
gets interesting.
Connected products bring together sensing, control, embedded software, enclosures, manufacturing and the interfaces people use to configure a system. A decision in one area can affect all the others.
03 / MY CONTRIBUTION
The work I brought
to the system.
Embedded firmware and sensing
Developed low-level C / C++ firmware with STM32 and Mbed OS. Work included peripheral communication and integration of sensing technologies such as radar, PIR, infrared, temperature and humidity.
Mechanical and manufacturing integration
Used SolidWorks, Fusion 360 and prototype work to connect PCB design with enclosure requirements. Coordinated with mechanical teams and manufacturers on components, materials, molding and quality-control needs.
Technical leadership with hands-on delivery
Balanced team direction and task oversight with firmware development, PCB work, prototyping and research. Collaborated with software and design colleagues to connect hardware behaviour with configuration and product workflows.
ENGINEERING NOTES / FROM MY FIGMA PORTFOLIO
The decisions
inside the product.
My earlier Kasper portfolio documents how the physical controls, PCB architecture and enclosure requirements shaped the hardware. These examples connect the finished product with the engineering behind it.
01 / SMART SWITCHSeparate the touch interface
from the power circuitry.
The upper board carried the MCU, capacitive touch sensing and other DC circuitry. The lower board grouped AC and communication components. This made the board arrangement part of the interface and enclosure design.
- Two-layer boards with different copper weights for the upper and lower assemblies
- UART, CAN, I²C, SPI and GPIO for sensors, drivers and device status
- Layout review considered clearances, trace widths and IPC-2221 guidance
02 / SMART PLUGDesign the board stack
around the load and assembly.
The smart-plug design used four-layer PCBs and a heavier-copper lower board for the load path. The upper board brought together the MCU, touch interface and sensing, with power-related components on the lower board.
The board arrangement and enclosure assembly were developed together for the Kasper product format.
03 / FAN & DIMMERShare the interface.
Adapt the power board.
A common upper board worked with two different lower-board variants for fan-control and lighting-dimmer applications. This reused the control interface across two product functions.
The two-layer boards separated MCU and sensing circuitry from AC and communication components, while retaining the device interfaces needed by the wider system.
IN-HOUSE PROTOTYPING
Build, assemble and investigate.
My Kasper workflow included 3D and resin printing for enclosure samples, Voltera PCB prototyping, SMD pick-and-place and reflow assembly, and Shapeoko CNC work for test parts. Oscilloscopes, multimeters and signal generators supported bench investigation.
THE PRODUCT ECOSYSTEM / KASPER
Many devices.
One connected home.
Kasper brings lighting, appliance control, sensing and automation into a shared home-control system. Its public product range provides context for the electronics, firmware and mechanical integration behind my work.

The wider user experience
Kasper describes app-based controls, schedules, scenes, energy visibility and voice-assistant integration. My contribution here focuses on the hardware, embedded firmware, prototypes and development tooling within that broader system.

04 / VALIDATION
Check the behaviour.
Development involved prototype bring-up, hardware rework, firmware debugging and test tooling. Oscilloscopes, logic analysers and JTAG supported fault investigation, while Linux / Python tools and test jigs supported configuration and validation work.

- PCB, firmware and mechanical collaboration
- Progression into engineering leadership
05 / OUTCOME & REFLECTION
What the work adds up to.
Contributed to a family of 7+ automation devices and progressed through three engineering roles. The work spans product development, prototyping, firmware and hardware validation, and manufacturing support.
Product ownership means staying involved beyond the schematic or firmware change. Manufacturing questions, service requirements and the people integrating the system are part of the engineering problem.
