What I've built

2025 – 2026

Five tables, one model
Consolidated five legacy grade tables into a single relational model and built the REST services to query, calculate and record grades.
National Conservatory of Music · MySQL, NestJS
Reports that generate themselves
One structured capture produces the PDF report, the Excel sheet and the delivery email. It works offline and leaves an append-only audit trail.
Abimatik Medical Instruments · React, PHP, MySQL
A data environment, operational again
Recovered and validated the institutional processing and reporting environment on AlmaLinux, integrating Apache, Python, ODBC and SQL Server.
ARCONEL · AlmaLinux, SQL Server
Computer vision
A YOLOv8 model reconstructs Amazons boards and moves from photos. It reached 99.50% mAP50 on the project evaluation.
Applied research · 2025

How I work

I build software so that data is useful and processes are reliable. I integrate frontend, APIs, databases and automation, with particular attention to integrity and traceability.

Preserve the evidence: Original data is stored with SHA-256 before it is interpreted.
Correct without erasing: Versioned corrections and append-only audit records.
Test and automate: Automated tests and delivery pipelines on GitHub Actions.

Experience

Aug – Oct 2026

National Conservatory of Music

Full-stack developer · Academic management system

A single academic model where there used to be five grade tables.

Worked on the migration and evolution of the platform across four frontend and backend repositories: the legacy system (Angular, Express/Sequelize) and the new one (Next.js, NestJS/TypeORM).
Unified five grade tables into a single academic model and built REST services to query, calculate and record grades (MySQL).
Implemented modules for students, guardians and enrollment, reports and the guardian portal, with validation, JWT access control and Next.js interfaces.

Abimatik Medical Instruments

Software developer · Technical reporting system

From structured capture to delivered report, with no re-typing.

Built an application that turns structured input into PDF reports, Excel sheets and delivery emails (React, TypeScript, PHP 8.3, MySQL).
Implemented offline capture, synchronization, versioned corrections and append-only audit records (IndexedDB).
Automated delivery and testing with four GitHub Actions workflows.

Public procurement data quality monitor

A foundation for preserving and assessing Ecuadorian public procurement data. Each source is fetched over HTTP, stored as immutable evidence with a SHA-256 fingerprint and persisted in PostgreSQL, with versioned migrations and automated tests.
