Senior Full-Stack Architect: High-Performance SaaS Infrastructure Migration (Figma Ready)

Project Overview: We are migrating an established SaaS platform from an outdated, legacy WordPress build to a high-performance, custom-engineered infrastructure. All 16 high-fidelity UI/UX layouts are already finalized in Figma. We are looking for an architect to build the "frontend shell" for SEO/Ads speed and the "backend engine" for secure data handling. Core Technical Scope: • Track 1 (Performance Frontend): Convert Figma designs into a 100% custom-coded environment. Objective: 95+ Mobile PageSpeed Score for optimized Ad-spend and SEO rankings. • Track 2 (Logic & Security): o Implementation of a custom pricing engine with dynamic percentage-based fee logic. o Development of a secure encryption vault for sensitive user credentials (AES-256). o Integration of a high-end REST API analytics dashboard. • Track 3 (Payments): Advanced integration of secure payment gateways for tiered subscription plans. Mandatory Technical Requirements: • No Page Builders: Zero reliance on Gutenberg, Elementor, or heavy plugins. • Security-First: Proven experience with OpenSSL and secure data transit. • Architecture: Ability to build modular, scalable PHP/JS that can handle high-volume data without performance lag. Note to Applicants: This is a high-confidentiality project. Shortlisted candidates will be required to sign a Mutual NDA before receiving the full Technical Mandate, Brand Identity, and Figma access.
