Full Stack Developer | WordPress & Craft CMS | API Structured Data

Howdy Everyone; my name is Sal! I am a Full Stack Developer specializing in CMS architecture, API integrations, and search-driven web platforms. I build structured content systems; not just websites. Over the past 6+ years, I’ve designed and implemented scalable platforms across WordPress, Craft CMS, custom commerce systems, and SaaS environments. My work often sits at the intersection of backend data modeling, search infrastructure, and user-facing application logic. If you need more than a theme installation, you’re in the right place. Core Focus Areas: • Custom WordPress & Craft CMS architecture • API integrations & external data ingestion • Structured data modeling & CPT design • Search systems (faceted filtering, ranking logic, schema definition) • Complex ecommerce workflows (account states, permissions, checkout logic) • Platform migrations & system continuity • Custom plugin / module development • Automation & workflow optimization Recent Engineering Highlights: Architected a queued ingestion pipeline integrating legislative API data into Craft CMS with Meilisearch indexing and SSR-rendered search delivery. Built bespoke WordPress systems for nonprofits and policy organizations, including structured metadata, community integrations (Circle.so), and content modeling. Worked across custom C# commerce platforms, IBM/HCL Commerce, and BigCommerce ecosystems. Implemented dynamic routing, rewrite logic, and AJAX-driven rendering for scalable content delivery. Why clients continue to work with me: • 100% Job Success Score • Long-term partnerships (multi-year contracts) • Clear communication between marketing and development teams • Production-ready solutions; not fragile builds If you’re looking for a technical partner who can architect and implement structured digital systems, let’s talk.
