What I'm looking for

I'm looking to lead or build scalable, secure applications with clean architecture, strong performance, and end-to-end delivery, while mentoring developers and advancing practical AI-enabled engineering workflows.

At Etrading Software Philippines, I lead development of trading and portfolio management systems for sell-side and buy-side clients using Java, Spring, Angular, and AWS. I also deliver third-party integrations through APIs, SFTP, and AWS S3.

I built and integrated an AI-powered chatbot with LangChain4j and AWS Bedrock, enabling natural-language queries for customer interactions and financial-data insights. I champion AI tool adoption through brown-bag sessions, workflow standards, code reviews, and clear code ownership.

Previously, I led Java developers building core banking modules at PearlPay and contributed to the Philippine government’s Probation Information System at Monstarlab. I mentor developers, promote engineering best practices, and focus on clean architecture, performance, and end-to-end delivery.
