John Mann · Personal workshop
Experiments in software, media, leadership, and the web by John Mann. Some are useful. Some are unfinished. All of them taught me something.
Selected work
Working software, prototypes, media, and useful leftovers.
Camera + interview overlay
Featured experiment
Lightweight layouts for interviews, live video, and screen recordings—built to explore how far the browser can go without a production suite.
Fitness tracking for personal trainers and clients, with workout assignment, progress tracking, and Supabase-backed dashboards.
A financial-literacy app where kids learn through interactive lessons, games, and savings goals.
Open-source uptime and response-time monitoring with incidents, alerts, scheduled checks, and billing workflows.
A deliberately small browser utility for capturing repeated time intervals without setup, accounts, or extra ceremony.
A visual scratchpad for testing motion, generated backgrounds, and atmosphere before every experiment has a practical purpose.
Recorded conversations about the people, decisions, and lived experience behind technical and creative work.
Practical writing and resources about engineering leadership, artificial intelligence, startups, and product execution.
Small archived experiments in resilient HTML, constrained layouts, and the unusually limited web platform inside email clients.
