Featured Projects
Notarial AI Suite
A vertical SaaS platform that helps Honduran notaries digitize and manage notarial documents using AI-powered data extraction. Upload scanned documents, let Gemini AI extract structured data, then review, search, and export authenticated records — all from the browser. Built with Next.js 16, Flask 3, Gemini AI, and Cloudflare R2 storage.
Mennonite Church Management
A comprehensive church management platform for the Mennonite Church in Honduras, featuring member management, ministry coordination, financial tracking, event scheduling, inventory management, and a dynamic public-facing church website. Built with Angular 21, NestJS 11, Prisma ORM, PostgreSQL, and Supabase Auth.
How To Train Your English
Hackathon-winning ($2K Devcon 2025) e-learning platform where kids ages 3-9 learn English alongside 'Trio' through AI-generated quizzes and text-to-speech narration. Behind the playful UI lives a robust LMS with Sequelize, JWT-based RBAC for three roles, and React Query.
NourAI
An AI nutrition assistant that fights LLM hallucination in health by anchoring every answer in a curated medical corpus with explicit citations. Built on a FastAPI RAG pipeline with factory patterns and a RAGAs evaluation framework that measures retrieval and answer quality.
FruitScanAI
A real-time computer-vision system that classifies fruit quality from a live camera feed using YOLOv8 and RF-DETR. Implements a full Human-in-the-Loop MLOps pipeline where users correct predictions on an HTML5 Canvas annotation UI to continuously fine-tune the model in production.
