Platforms I've Built
Every project below was built end to end — strategy, architecture, and hands-on delivery — not handed off between teams. The numbers attached to each one (rows reconciled, services shipped, tests passing) are real, and the stack listed is what actually runs in production, not what looked good on a pitch deck.
AIDA — Enterprise Tax Compliance Platform
Costa Rican VAT (IVA) reconciliation rebuilt from scratch: 1.05M import rows, 6 generated reports, and a 4,900-line tax engine that replaced a legacy VBA macro.
AI Persona Clone — Voice + RAG over Your Own Documents
An AI persona that talks in your voice, retrieves only from documents you trust, and listens back — built first on Gemini, then hardened into a local-first enterprise RAG stack.
Tools Dashboard — Multi-Tenant SaaS Admin Platform
A multi-tenant admin platform with Kong 3.4 gateway (WAF + 3-tier rate limits), Google OAuth + TOTP 2FA, four databases, and an OAuth app-store that logs users into other apps with one click.
Web Teleprompter — Self-Hosted PWA with Browser-Only Adaptive Scroll
A self-hosted teleprompter with four device-handoff modes (QR, chunked QR, LAN, relay+OTP) and a voice-driven scroll that runs entirely in the browser — no cloud, no accounts, no database.
E-Cards Platform — Template Engine + LLM Batch Personalization
A card-rendering platform that ported a 10-year Adobe InDesign JSX pipeline to the browser, then added LLM-assisted batch personalization — rendering thousands of cards per run.
Tools Project — Self-Hosted Project Management Hub
A vertically integrated project platform with 21 database tables, polymorphic activity feeds, dual-mode auth, Kanban boards, and a full CRM pipeline — no Redis, no Celery, no message queue.
