About Me

Hi, I'm Jonathan! 👋

I'm a Data Engineer with a unique journey that started in healthcare technology and led me to the world of data engineering. With 5 years of experience in data science and engineering, I specialize in building efficient, scalable data solutions while maintaining strong security and compliance standards.

My Data Journey

My tech journey began in an unexpected place - the operating rooms of St. Luke's Medical Center in the Philippines. As a Biomedical Equipment Technician, I ensured the reliability of critical medical equipment during surgeries. This experience taught me the importance of precision, reliability, and the real-world impact of technology on people's lives.

Following this, I transitioned to Sky Cable Corporation, where I worked in operations support. Here, I optimized broadband experiences by eliminating system noise and maintaining network signal quality. During this time, I studied data science on my free time and that opened up opportunities for me. DXC Technology sponsored my Master's Degree in Data Science at Drexel University.

From Philippines to Philly

I moved from my home country to the US in 2019 and my entry into data science came through DXC Technology's AI Studio, where I worked on fascinating projects including ML models for racing analytics and AI-powered VR applications. This experience opened my eyes to the power of data and machine learning, but I am also increasingly drawn to the infrastructure that made these applications possible.

From Data Science to Data Engineering

I transitioned from part time to full time as a Senior Data Engineer at DXC Technology Platform X, I focused on optimizing data workflows and implementing robust security measures. One of my proudest achievements was reducing our global data lake storage costs by 63% while maintaining data integrity and compliance. I also improved ETL latency by 96% through strategic data flow migration of enterprise tables.

Key Achievements

  • Reduced global data lake storage costs by 63% while improving data integrity and compliance
  • Enhanced data pipeline performance, improving ETL latency by 96%
  • Improved observability and lineage of Comcast Device Analytics by 70%
  • Implemented GDPR-compliant data security solutions

Education & Credentials

  • Current: MS in Information Systems and Engineering Management, Harrisburg University
  • 2021: MS in Data Science, Drexel University (GPA: 3.92)
  • 2014: BS in Electronics Engineering, Polytechnic University of the Philippines

Beyond the Code

When I'm not working with data, I'm an avid distance runner (find me on Strava), sharing knowledge through technical writing, and staying active in the Philadelphia tech community. I'm passionate about making complex technical concepts accessible and helping others navigate the ever-evolving world of data engineering.
