PORTFOLIO & ACADEMIC RECORD

Jotham Hernandez

ICT Professional | Graduate Researcher in ICT Convergence | Digital Government and AI Systems

Emphasizing the intersection of ICT infrastructure, public-sector digital transformation, AI-enabled systems, and education to drive institutional excellence.

Profile

Synthesizing Practical Systems with Institutional Knowledge

My professional journey has evolved from a foundation in web development and IT education to leading public-sector ICT transformation and cloud systems architecture. As an Information Technology Officer, I bridge the gap between building resilient digital infrastructures and the strategic frameworks that govern them.

Currently pursuing a Master's degree in Policy Competency in ICT Convergence at Handong Global University, my research trajectory focuses on how institutions can leverage AI-enabled systems and digital government policies to create sustainable, human-centered ecosystems.

Outside of my professional and academic pursuits, I remain a lifelong student of technology, constantly exploring the latest in cloud infrastructure and cybersecurity.
