Aeroshi / Engineering services
Electronics, firmware and product development.
Commission a work package or ongoing development support with Arek Kaniewski as your engineering lead. Responsibilities and milestones are agreed up front, with progress, decisions and test findings kept visible through to handover.
New development · Product revisions · Team support
Electronics & firmware
Bring the board and embedded software forward as one workstream, from component selection and PCB layout through bring-up and device behaviour.
- Schematics, PCB layout, BOM and manufacturing files
- Firmware source and documented bring-up findings
Tools & platforms Altium · KiCad · C/C++ · ESP-IDF
Other engineering work
Low-power RF board redesign
RF board redesigned around its duty cycle after measuring active, standby and transition currents.
<10 µA quiescent current
Connected systems
Join device firmware, telemetry and software into a usable system, with provisioning, remote updates and access to the data that matters.
- Device integration, APIs and monitoring dashboards
- Software source, configuration and reporting outputs
Tools & platforms Wi-Fi · TypeScript · Next.js · PostgreSQL
Read the connected-product case study
BeagleBone to Raspberry Pi Pico
Developed C firmware and a verification setup for a controller platform migration, including correction of a battery-management state-machine fault.
Testing & production support
Investigate faults and verify changes with measurements, test fixtures and repeatable checks, carrying findings back into the hardware and firmware.
- Current measurements, fault diagnosis and test tooling
- Agreed test records, findings and handover documentation
Tools & platforms Python · Oscilloscopes · Production test fixtures
Other engineering work
Production UART fault investigation
Multi-board test fixture built and UART instability after bootloading diagnosed.
Removed recurring line-stop failures
