Senior Backend Engineer
About Me
I am a Senior Backend Engineer with extensive experience in Python, Node.js, PHP, Java, and .NET technologies. Over the years, I have developed scalable APIs, event-driven systems, and cloud-native applications that support high-volume e-commerce transactions, real-time healthcare workflows, and enterprise automation. My expertise lies in solving complex backend problems, enhancing system reliability, and delivering production-ready solutions across cloud platforms such as AWS and Azure.
I have a strong background in building backend services that automate document ingestion, validation, and workflow processing for compliance systems in healthcare and real estate. I am skilled in developing asynchronous processing systems using RabbitMQ and cloud queues to ensure stable and efficient operations for time-critical tasks.
My experience includes designing and implementing CI/CD pipelines using Azure DevOps, Jenkins, and Docker, which have significantly improved deployment reliability and reduced release errors. I am also proficient in enhancing observability through tools like Azure Monitor, Prometheus, and Datadog to enable fast issue detection in compliance-heavy environments.
I have contributed to building fraud analysis engines and event-streaming pipelines with Kafka and RabbitMQ, reducing fraud detection times drastically and supporting millions of daily transactions. I am adept at creating secure REST and gRPC APIs for payment routing, identity verification, and fraud scoring across global banking partners.
In addition to backend development, I have experience with frontend technologies such as React, Vue.js, and REST APIs, enabling me to deliver comprehensive client-facing portals. I am committed to continuous improvement and modernization of deployment processes using GitHub Actions, Docker, and Infrastructure as Code principles.
I hold a Bachelor of Science degree in Information Technology Entrepreneurship from Ateneo de Manila University. I am passionate about leveraging technology to build reliable, scalable systems that drive business success and improve operational workflows.
