Hello, I'm Joel Jonassi

I close the gap between devices, people and software.

About Me

I work where hardware meets software meets humans. Messy problems, real solutions.

Joel Jonassi

I am a Computer Systems Engineer. build things that sit at the intersection of hardware and software, where a wrong byte crashes a device, not just a browser tab. My focus is on closing the gap between people, machines, and the software that connects them.


Things I'm working on / thinking about

  • Embedded systems & kernel-level programming
  • RAG pipelines and AI Agents
  • ML / DL applied to real problems
  • Ride-sharing systems with GSM fallback
  • Agriculture × technology
  • Building things that shouldn't exist yet
