Stefan Lubbe

Systems integrator and self-taught software developer with four years of production experience across embedded hardware, enterprise security infrastructure, full-stack software development, and applied AI/LLM engineering. Designed custom PCBs from schematic to finished product and personally deployed them across hundreds of live sites. Outside of work, spent the past year building and launching an independent real-time geospatial intelligence platform — now live in production with a growing base of paying users — and works hands-on with self-hosted and finetuned large language models.

Holds three Milestone certifications. Takes end-to-end ownership of whatever is in front of me and prefers to fix root causes rather than patch symptoms.
