How I engineer.
Built to scale
Enterprise habits on every project: clear architecture, documentation and systems that stay maintainable as they grow.
Secure by default
Encryption on-device with AES-256-GCM, hardware-backed keys and least-privilege design, from Intune policy to my own apps.
Lean by design
TV Index replaced a £30/month AWS backend with a zero-cost architecture. Cost is a design constraint, not an afterthought.
Private by default
Every app I build is ad-free with no tracking. Data stays on the device unless you choose otherwise.
