adam93
I'm Adam Broadbent. By day I'm the commercial lead at a Swedish startup. By night I'm a solo founder and builder, shipping apps, AI tools and the odd hardware hack.
Things I've built
RG35XX Unchained
Root access, a custom console UI and out-of-tree kernel modules for a $60 retro handheld, all without reflashing it.
Jetpump
Say "deploy" to your AI coding agent and get a live HTTPS URL back. No dashboards, no YAML.
The Strength Society
A strength-training log with an AI coach built in. It writes your program and never changes anything without asking.
Läsa svenska
AI-written Swedish stories, checked by a linguistic validator, pitched at exactly the SFI course level you're on.
Runner Bean
A run tracker you pay for once. No account, no subscription, and nothing leaves your phone.
Fair Price Engine
A home-built ML valuation engine for Swedish used cars, trained on about 130,000 listings and deliberately kept from cheating.
Too weird for their own domain
- LAB-01Projector Pit StopWhy one press on the remote moved four times, and how ADB alone cut the time to the launcher from 18.3 s to 10.3 s.→
- LAB-02DiskCleanupSmart macOS disk cleanup with an animated sunburst map, and nothing deleted without asking.→
- LAB-03MiseA local-first meal planner that uses linear programming to balance macros and cut food waste.→
- LAB-04Pi Automation BoxSelf-hosted n8n on a Raspberry Pi 5, with TLS, a firewall, private search and backups.→
- LAB-05London Property MapLondon house prices layered with schools, transport, green space and energy ratings on one map.→
Field notes
- 2026-11-11Why adam93 existsA home for projects that are too experimental to get their own domain, and a place to write up how they were built.
- 2026-11-02Why my projector's remote pressed every button four timesA boot profile over ADB, an accessibility service nobody asked for, and a 400 ms key-repeat timer. No root, every change reversible, and the launcher now appears in 10.3 s instead of 18.3 s.
The short version
I’ve spent my career turning car-industry ideas into products people pay for. At Lynk & Co I launched a car-sharing service from scratch, grew it to 10,000 monthly users, then ran the team behind its financing and insurance products. Today I’m the commercial lead at a Swedish startup. In the evenings I’m a solo founder and builder: I keep up with AI, dig through GitHub repos and ship my own products.
