Technology Lead · 2021 — 2023
Overview
Complete institutional digital transformation of a Guatemalan research and education organization. I was the sole technical owner from day zero to production: backend platform, frontend portal, network infrastructure, and institutional identity — all designed and delivered under a single technical vision.
The institution was operating with legacy systems and physical infrastructure that couldn't support modern academic and research workflows. The transformation required rebuilding from the ground up while keeping operations running.
What I built
- —Led the technical process of institutional rebranding and digital identity definition under the CRAI model.
- —Designed the architecture of a modular academic software ecosystem (Java, Spring Boot, MySQL, Liquibase) — covering library catalog, research repository, user management, and administrative modules. Defined engineering standards and guided developers through implementation.
- —Redesigned the institutional web portal in React, working alongside UI/UX design to deliver a structured digital experience for students, researchers, and staff.
- —Designed and implemented the complete network and connectivity infrastructure: VLAN segmentation, pfSense firewall, enterprise-grade access points — transforming a physical space into a technology-ready environment with separated networks for staff, students, research lab, and public access.
Architecture decisions
Chose Java/Spring Boot with Liquibase for schema version control from day one — critical for an academic system where schema stability is non-negotiable. VLAN segmentation was designed to isolate sensitive research data while enabling guest access without compromising institutional systems.
