About
At 21, I'm delivering production software for multiple international clients simultaneously, while completing a Computer Engineering degree at Cavite State University (GPA 1.58/1.00, graduating February 2027; on the Philippine grading scale, 1.0 is the highest distinction).
My work spans full-stack development, automation engineering, and internal tooling: systems built to handle real business operations at scale. Within my first month with my primary UK client, I was appointed technical team lead. I currently work with clients across the UK, the US, Singapore, and the Philippines.
I integrate Claude Code and Gemini CLI as core parts of my engineering workflow, using AI tooling to move faster without sacrificing output quality.
What I work with
What Clients Say
“One thing that has stood out to me is his ability to deliver projects earlier than required while still maintaining quality and professionalism. He has been reliable, easy to work with, and quick to understand project goals and technical requirements. I already have additional projects lined up for him moving forward.”
“Messages get answered fast, tasks get picked up without chasing, and the quality of the work coming back reflects genuine care for getting it right. That combination of capability and adaptability is rare — it is what makes him genuinely useful on product development work rather than just task execution.”
“Dave has been a reliable and proactive technical teammate. He takes ownership of real product issues from triage through resolution and keeps momentum without needing constant hand-holding. When given a clear task list, he moves quickly, asks good questions when needed, and follows through.”
“Dave has been a great asset to our business. He consistently delivers high-quality work, pays close attention to detail, and is thorough in his approach. He communicates clearly throughout the project process and is always organized and proactive — exactly what you want in a technical contractor.”
