App development, built secure

I build web apps for real business problems: CRMs, invoicing, encrypted record systems. Being a qualified network security engineer means security is designed in from the first line, not added at the end.

What's included

  • Secure by design

    Least privilege, hardened sessions, CSRF protection and strict content security policies.

  • Encryption where it matters

    Sensitive records encrypted with keys the server never sees, where the job calls for it.

  • Tested properly

    Automated tests and attack probes before every release.

  • Light hosting

    Runs on ordinary hosting without heavy frameworks or big monthly bills.

How it works

  1. Map the workflow

    How the work happens now, and where it hurts.

  2. Threat model

    Who should see what, and what an attacker would try.

  3. Build in slices

    Usable pieces early, with tests from day one.

  4. Audit and launch

    A security pass with attack probes, then go-live and support.
