Alexander Svarvare

Embedded Linux Engineer | Axis Communications AB

I code Yocto Linux C-drivers for body-worn systems, focusing on thermal and battery management subsystems across both userspace and kernel. I follow strict coding standards for safety critical code and have had to apply lock-free mechanisms to prevent race conditions. I ensure long-term software compatibility by following official Linux standards and contributing code to the mainline kernel.

Sole Algorithm & Embedded Systems Engineer | Infonomy AB

Hired as the sole engineer at a MedTech startup directly following graduation. Took full ownership of developing the hardware and application code for a multi-device product. The product consisted of a hub-sensor-cloud setup where the sensor (accelerometer/gyro) is situated at the patient's thigh to extract unique physiological data.

• Software Optimisation: Achieved 100× data throughput by implementing backpressure, octet-stream and asynchronous worker pools. Reduced power consumption by 50% by improving stop-mode usage and applying adaptive clock frequency.
• Edge Computing: Lowered AWS operational costs by migrating data pre-processing from cloud to hub, reducing required vCores in cloud.
• Hardware: Restructured the messaging design, which freed CPU pins to allow for SPI which together with DMA moved the data transmission bottleneck elsewhere.
• Hardware Debugging: Identified a critical system instability using oscilloscope verification, proving a hardware design error that I fixed in firmware.
• Manufacturing: Designed and 3D-printed custom production pogo-pin rigs [View Custom Jig], bypassing expensive industrial tooling and accelerating iteration cycles.

Research Internship | EIT LTH/IEEE

Awarded the IEEE AP-S Undergraduate Summer Research Scholarship with the project ”Massive MIMO Array Characterisation and Design Using Trimodal Patch Elements”. My professor recruited me for research after receiving top grade in his course Electromagnetic Theory.

Radar Summer Internship | Axis Communications AB

Explored and drafted calibration methodologies for radar arrays. Calibrating radars takes up valuable production floor space which the company sought to reduce.

Self-employed electronics repairman (Since age 12)

Diagnostics, water-damage repair, SMD-soldering, replacement and repair of consumer electronics.

Instructor & Leader | Flygvapenfrivilliga (FVRF)

Progressed from participant to instructor. Employed by the Swedish Armed Forces to lead military summer camps, managing groups of 50+ youth in high-discipline environments.

Self-designed Linear Microphone Array for drone detection

Designed the PCB in KiCad [View Whole Project]. Corrected wiring errors by manually re-routing 0.2 mm traces [View Closeup of Re-soldering] using a razor blade [View Cut Traces] and fine-gauge copper wire.

The system utilises an STM32 as an intermediary driver to sample sound from 8 PDM-mics, convert to PCM, and package the data for transmission over USB to Python. Current capabilities include verification of synchronous sampling and an angle estimation algorithm (MUSIC) with real-time visualisation.

$$P_{MU}(\theta) = \frac{1}{\mathbf{a}^H(\theta)\mathbf{E}_n\mathbf{E}_n^H\mathbf{a}(\theta)}$$

Custom-built 10S9P Samsung 18650 25R e-bike battery system

Engineered a 1+ kWh battery pack to cover my transportation needs instead of buying a car. The project included cell spot-welding, BMS integration, wiring, and mechanical mounting.

Speciality Tool for Bike Seat Post Extraction

My girlfriend's bike seatpost had totally seized due to galvanic corrosion between the aluminium seatpost and the steel-bikeframe.

I MMA welded the poles, TIG welded the handle and CNC metal lathed the axial ball-bearing housing. [ View Tool ]
