Hi, I’m Matjaz — an engineer and tinkerer by heart and someone who learns fast and likes to solve hard problems with technology.
Since I’ve been a kid, I hard to urge to take things apart. I started on computers at age 7 (DOS, Windows 3.1, Logo), built my first website at 12, went to technical high school for computer tehcnicians and then on to do a computer science degree at FERI in Maribor (Slovenia). Throughout my career I went from an individual contributor to team lead and then CTO and back, because I missed getting my “hands dirty”.
From backend code, data analytics and Google Cloud, to now embedded systems, I pick up new things fairly quickly and love to dig in and go deep.
Recent experience #
Embedded Developer — Mono Technologies
- Built a Raspberry Pi test jig/device covering the full board pipeline (JTAG bring-up, QSPI/eMMC flashing, OpenWRT/Linux programming, network validation). We used it to process our first 1,000 boards.
- Helped trace a board-bricking firmware bug to a PD-controller timing gap and proposed a datasheet-correct fix.
- Did PoC for flash recovery on a semi-dead board by injecting power and controlling the flash chip directly using PCB probes, logic analyzer and Tigard.
- Did a PoC for capturing JTAG communication between proprietary debugger and the LS1046a with a JTAG breakout board and logic analyzer.
- Did a PoC for JTAG semihosting on LS1046A with cheap non-proprietary JTAG probe/debugger.
- Validated and tested 10 GbE and IPSec hardware offloading.
- Designed a GPIO adapter board in KiCad.
- Wrote developer documentation covering the full boot chain (PoR → PBL → BL2 → BL31 → U-Boot → Linux) and flashing different operating system images.
- Prepared the data room for investors
CTO / Tech Lead — Codeable
- Led the product and development team.
- Was responsible for everything technology (cloud infrastructure/DevOps, data/analytics stack, software development, …)
- Built and ran the Google Cloud and Kubernetes infrastructure, CI/CD, and backend (Ruby on Rails).
- Designed the data stack (PostgreSQL, Airflow, BigQuery, Looker) and delivered dashboards, A/B tests, and Bayesian analysis.
- Did all the data analysis from Looker to manual Python analysis (Jupyter, bayesian analysis, …)
- Wrote Ruby backend with extensive test suite for the web app.
