Senior Software Developer at Vehikl
Guelph, Ontario, Canada
Summary
👤
SeniorGerrie Swart is a pragmatic senior software developer and founder with two decades of industry experience and a nine-year track record in senior roles, currently building resilient systems at Vehikl from Guelph, Ontario. He has hands-on expertise architecting and re-engineering high-throughput, high-uptime transactional platforms—most notably as a co-founder of Flickswitch where he led core system design processing millions of real-time transactions. Gerrie blends strong backend engineering (Java, Python, PHP, MySQL variants) with a product-minded focus that balances elegant design and rapid MVP delivery. He fosters open, fearless team cultures that reliably meet estimates and scale, and contributes to open-source BPM work such as ProcessMaker’s core by improving validation, schema, and API logic. Not obviously visible from titles alone, he prefers staying technical to avoid managerial drift and repeatedly rescues systems from instability to production-grade reliability.
