Full-Stack Developer · Balayan, Batangas, PH
I’m Prince Arvee Avena, a Full-Stack Developer at ServiceCo specializing in web and mobile platforms built on one shared codebase. My work spans the whole stack: PostgreSQL schemas and APIs, React and React Native interfaces, AI features that answer from a company’s own data, and automated deployments on AWS. With a strong background in TypeScript, Laravel and cloud infrastructure, I take products from the first database sketch all the way to production.
Since 2024 I have designed and delivered systems for businesses, schools and local government offices across Batangas and Cavite, many of them running in production today. They cover point of sale, Philippine-compliant payroll, clinic management and public records, each built hand in hand with the people who run them every day. I graduated Magna Cum Laude in Computer Science.
I build software that is reliable, secure and simple to use. Role-based access, audit trails, backups and CI pipelines are part of every system I ship, not an afterthought. I’m committed to growing as an engineer and building technology that makes real work faster for the people who depend on it.
