Senior full‑stack engineer specializing in scalable serverless systems.
PhilippinesWhat I'm looking for
I design and build end-to-end full-stack products that scale with business needs, from robust backend APIs to polished user interfaces and reliable AWS infrastructure. I am an AWS Certified Developer focused on serverless systems, cost-efficient cloud architecture, and SaaS/CRM platforms.
At OpenText I architected and delivered scalable SaaS and CRM platforms using AWS, Node.js, and React.js, led serverless transformations and refactors with measurable improvements in cost and reliability. Previously, I led backend redesigns and AWS migrations that substantially cut infrastructure costs and improved performance across B2B SaaS platforms.
I deliver production-ready engineering that speeds launches and reduces cloud spend, and I act as a long-term technology advisor who aligns architecture with business growth. I thrive in cross-functional Agile teams and prioritize observability, CI/CD optimization, and pragmatic modernization.
