Sub-30-second automated follow-up with complete conversation transcript and audio logged to CRM.
Conversational Product Discovery & Knowledge Support Engine
A multi-category catalog created friction in product discovery and placed heavy repetitive load on customer support staff.
Engineered a custom WordPress plugin that indexes product attributes into a vector store and powers a contextual conversational assistant via WooCommerce REST endpoints.
Automated resolution of routine pre-sale product inquiries and instant catalog recommendations.
Autonomous Real Estate Inbound Voice Assistant & Booking Agent
International property inquiries across disparate timezones suffered delayed response times and lost viewing opportunities.
Designed a conversational voice agent using Vapi and ElevenLabs connected via Make.com to qualify buyer budgets and book viewing appointments directly into team calendars.
Near-real-time inbound call handling, automated qualification against criteria, and automated calendar scheduling.
Structured Content Research & Draft Publishing Pipeline
Manual research, drafting, formatting, and uploading structured educational articles was bottlenecking editorial throughput.
Built an automated pipeline that queries verified research data, generates structured drafts with metadata, and creates scheduled drafts in WordPress via REST API.
Streamlined drafting and staging workflow with human-in-the-loop review prior to publication.
Enterprise WordPress Core Performance & Structured Data Overhaul
Bloated scripts, unoptimized database queries, and absent structured data caused poor mobile performance and diminished search discoverability.
Refactored template hierarchy, implemented edge caching via Cloudflare, removed render-blocking resources, and built comprehensive entity JSON-LD schemas.
Sub-second mobile first contentful paint and rich entity indexing across search engines.
High-Volume WooCommerce ERP Bi-Directional Synchronization
Manual inventory and order synchronization between WooCommerce and an external ERP resulted in stock discrepancies.
Developed a custom PHP plugin with background queue processing, webhook event listeners, and automated failure retry handling.
Reliable bi-directional order and inventory synchronization with automated error logging and zero data loss.
