From WordPress Monolith to Astro 5 Islands

Eliminating mobile latency, vulnerability vectors, and unqualified lead friction.

LEGACY WORDPRESS

The Legacy Dilemma: WordPress & Elementor Bottlenecks

The previous acquisition channel ran on WordPress with Elementor, suffering 6s+ mobile load times on cellular 3G/4G connections, recurring plugin conflict crashes, and high lead abandonment. Additionally, unfiltered web forms allowed submissions from out-of-coverage provinces and unsupported payroll banks, overwhelming underwriting staff.

• 6s+ mobile load times on cellular data
• Crash risks due to unvetted plugin updates
• High bounce rates during initial form discovery

ASTRO 5 + TYPESCRIPT

The Transformation: Astro 5, TypeScript & Vanilla CSS

Rebuilt from the ground up as a high-performance Astro 5 application with strict TypeScript and zero UI framework bloat. Utilizing native CSS variables and islands architecture, mobile page loads dropped under 1 second (<1s) globally, delivering sub-second interaction across all mobile viewports.

• Sub-second (<1s) mobile page loads
• Native CSS tokens with zero runtime overhead
• 2-step ergonomic intake form

Inversion of Control & Symbiosis with SoliPres Core

The public frontend acts as a symbiotic intelligent facade for SoliPres: 1) Base62 Token Interception: Detects s.solufime.com short links to unlock pre-approved re-engagement offers up to RD$100,000. 2) Advisor Attribution: Persists ?asesor=ID&origen=canal query parameters in sessionStorage and injects attribution directly into WhatsApp consultation links and submission payloads. 3) Silent Geocontrol Disqualification: Applicants from outside Greater Santo Domingo or with unapproved banks are quietly filtered without showing rejecting error messages, preventing malicious address tampering.

01 • RE-ENGAGEMENT INTERCEPTOR

s.solufime.com Base62 Tokens

Unlocks pre-approved offers up to RD$100,000 for returning borrowers with instant dynamic amortizations.

02 • ADVISOR ATTRIBUTION

?asesor=ID&origen=canal

Persistent sessionStorage tracking guarantees 100% of incoming inquiries remain bound to their originating advisor.

03 • SILENT GEOCONTROL

Anti-Tampering Disqualification

Out-of-coverage applicants are quietly filtered backend-side without leaking underwriting rules to users.

FRAMEWORK ASD v2

AI-Driven Verification & Quality Assurance

Built under Framework ASD v2 standards, combining Vitest unit tests for loan amortization algorithms, Playwright for end-to-end multi-device simulation, and automated anti-PII scanners ensuring statutory compliance with Law 172-13 before production deployment.
