Thinking out loud, so the next person starts further along than I did.
an introduction, lowercaseThe short version.
Nothing we build works alone. Software talks to a network, a database, a device, a person. I've always been more interested in those connections than in any single part — that's the thread through everything I do.
I started on the founding team of a startup, doing a bit of everything: writing software, testing it, keeping servers and networks running. Today I design IoT systems at i45G, rebuild a healthcare platform at O2D3, and run Kiospal — a community where students and first-time founders learn by building. I believe technology only matters for what it lets people do.
