I’m Jomari Aquino Tuazon, a senior software engineer with 6+ years of full-stack experience building regulated fintech and open-banking consumer products. I focus on creating secure, mobile-first onboarding and financial applications using React Native, Expo, and Node.js, while ensuring systems meet privacy, consent, and audit requirements. I enjoy designing data models and scalable backends with PostgreSQL, integrating third-party providers like Flinks for account-data ingestion, and partnering closely with compliance, product, and engineering teams to deliver MVPs that are both reliable and user-friendly. From event recording and audit trails to performance optimization under high concurrency, I care about building fintech workflows that stand up to real-world regulatory expectations.
