Welcome to JCall Engineer

I’m John Call — an electrical engineer who spends most of his time writing software. I write low-level software, optimize CUDA kernels, and build distributed systems. I also, against my better judgment, keep ending up with GUI projects.

What’s here now:

• Blog — technical writeups, policy essays, and the occasional overengineered proof
• Rui — a Discord bot that detects and intercepts scam campaigns

What’s coming:

• Fundos — a local-only personal finance software for people who don’t want their bank data in someone else’s cloud
• Pixonomy — a tag-based image and metadata manager with mobile-to-desktop sync
• CV
