I'm a full stack developer based in Mérida, Mexico, with experience across React, TypeScript, React Native, and Odoo. Lately I've been focused on building AI-powered systems with LangChain and LangGraph, on top of my background building responsive web/mobile apps, enterprise systems, and medical software. Always learning, always building.

Things I've built
Portfolio
A sleek and high-performance personal portfolio built with Astro, designed to showcase my work as a frontend developer. The project leverages Tailwind CSS for rapid and responsive UI design, and TypeScript for type safety and scalable development. It features animated project cards, dark mode support, and clean, accessible design. The content is managed dynamically via Sanity CMS, enabling easy updates without code changes. Optimized for SEO and speed, the portfolio highlights my expertise in modern web technologies across both web and mobile platforms.

imagisSRM — DICOM Structured Report Authoring & PACS Integration
Desktop application in C++/Qt5 for composing, versioning, and transmitting DICOM Structured Reports (SR) in clinical radiology workflows. It integrates searching and retrieving studies directly from a PACS over the DICOM network protocol (C-FIND/C-GET), generation of real SR reports with DCMTK, and transmission via C-STORE with configurable AE Titles. I built a complete report-versioning lifecycle (reusing the UID for edits vs. creating new reports, per-study report history) and a visual picker for selecting slices/images from a study. To validate the end-to-end flow, I stood up a real test PACS (dcm4chee-arc-light) with Docker Compose, seeded it with synthetic DICOM datasets, and diagnosed production-simulated DICOM interoperability failures (patient-identity conflicts from Issuer-of-PatientID hashing, C-STORE rejections, UTF-8 character set issues in SR documents). I also ported the project from its original toolchain (Linux/GCC) to macOS/Clang, resolving ABI incompatibilities and CMake configuration issues with DCMTK/Qt5 via Homebrew.
