Beyond infrastructure, I build and maintain production software for clients in Lagos. Try them: run the security review one passes, and ring up a sale on the other.

Cloud Dimex LTD, an AWS consulting company in Lagos

Cloud Dimex marketing site

A cloud consultancy is judged on its own site. It had to load fast, pass a security review, and collect enquiries without leaking anything.

Security and quality review
  • Content Security Policy with SHA-256 hashes, no unsafe-inline
  • Live chat runs under the policy with a per-build nonce
  • HSTS preload and a full set of security headers
  • Analytics waits for cookie consent
  • Form guarded by hCaptcha, a honeypot and server validation
  • No horizontal overflow from 360px to 1440px
