Career

Work experience

Imagen de la experiencia profesional

Dirección de Relaciones Internacionales (DRI)Current

Systems Analyst | Data, Automation & Applied AI

I expanded my work into data analytics, automation, and AI integration while continuing as MoveON's functional owner. I organized, cleaned, and normalized internationalization data; structured relationships between sources using a star-schema-style model and connected them to Power BI to support data exploration and informed decisions. I automated document generation in Google Docs, data capture with Google Apps Script and Google Sites, Gmail communications, and auditable operation logs in Google Sheets, reducing repetitive work and supporting standardization. I also worked on integrating AI with the area's systems and workflows. Invited by QS, I presented the MoveON case at QS Budapest 2026.

Dirección de Relaciones Internacionales (DRI)

Implementation and Technical Support Specialist

I was the primary functional point of contact for MoveON, the platform used to manage agreements, mobility, and forms. Through interviews and ongoing sessions with the mobility team, I gathered and organized requirements, then translated them into platform configurations and digital workflows. I also supported process digitization and platform adoption.

About me

Turning technology into practical solutions

Retrato de Juan David Loaiza

I'm a Systems Engineer building end-to-end software, from interfaces and APIs to databases, integrations, and automation.

I apply AI by connecting models and agents to existing tools, data, and workflows; my focus is not model training. I also use coding agents in my daily workflow and work with specifications (Spec-Driven Development), vertical slices, and short iterations.

I quickly adapt to the technologies and resources available, learning how to use them to solve practical problems.
