Answers & Clarity

Frequently Asked Questions

Key answers about technical stack choices, sandbox demo security, timelines, and contract delivery.

Q1. What is your development and deployment methodology?
▾
We follow a rigorous five-stage methodology: Discovery, Architecture, Agile Engineering, Rigorous QA, and Immutable Deployment with automated rollback capabilities.
Q2. Do you build on custom PHP or standard CMS frameworks?
▾
We build both: custom enterprise vanilla PHP micro-architectures with zero framework overhead, and customized, headless, or hardened WordPress instances.
Q3. How do you handle ephemeral databases and demonstration security?
▾
Each interactive preview is provisioned inside an isolated ephemeral database container with strict time-to-live restrictions and auto-reset triggers.
Q4. What security standards are applied to projects?
▾
Every product adheres to OWASP Top 10 standards: strictly prepared PDO statements to eliminate SQL injection, contextual UTF-8 escaping, cryptographically secure CSRF token rotation, and AES-256 database encryption.
