01 About

Engineering clarity into complex systems.

I’m a software engineer with 2+ years of commercial experience building backend and cloud-based applications using Node.js, TypeScript, AWS, PostgreSQL, and MongoDB.

That commercial background spans REST APIs, CI/CD, Docker, and production systems. Separately, I have hands-on experience with Python, Scikit-learn, Natural Language Processing, Jupyter Notebook, and supervised text classification, with a focus on applying software engineering practices to practical AI/ML solutions.

How I work

Clear contracts, pragmatic architecture, and thoughtful trade-offs. I care about systems that remain understandable as teams and traffic grow.

What I’m looking for

B2B engagements, contract roles, and full-time opportunities in remote teams worldwide or hybrid teams in Metro Manila.
