Dev / Maker / Engineer

Hi! I'm Martijn, pleased to meet you. I'm an electrical engineer by background, specialized in software for embedded devices and digital signal processing. Over the years, I've branched into all-round true full-stack software engineering. What do all of these fancy titles really mean? I just like to analyze things, take them apart, design them, and build them up again. I'm a dev, a maker. I like to solve problems!


Work Experience

Software engineer

CodaBox | Aug 2018 - Present

CodaBox is an energetic scale-up fintech supporting accountants and bookkeepers in delivering their documents in digital format. I mainly work here as a dev on the monolithic python / django backend that takes care of the retrieval, processing and delivering of documents in digital format. I work on both keeping the current stack operational as well as evolving it on a functional but also technical level e.g. to a more service-oriented like architecture.

Afterwards, this involved into the ‘Marketing Automation squad’, where I got more into the job of analysis, combined with software development.

Their main product at the time was a device to monitor the respiratory health of fattening pigs based on sound, the ‘Pig Cough Monitor’. Given the size of the spin-off company at the time, I had various different responsiblities, ranging from the research of the sound analysis itself, to design of the hardware that was used, customer contacts as well as on-site support for the installations.
