About Me

16+ Years of Experience

Ts. Professional Technologist

I am a Software Engineering Manager with 16 years of software engineering experience and 8 years in technical leadership. I specialize in architecting secure, scalable solutions and driving complex, cross-border digital transformations — consistently bridging the gap between heavy technical execution and regional business strategy.

At Fiuu, I lead large-scale regional payment deployments across Southeast Asia, including the successful rollout of Apple Pay, Google Pay, and Samsung Pay for BDO in the Philippines and active integration of CIL ID Token and BRI channels for the Indonesian market. I manage a rigorous five-stage escalation process alongside regional stakeholders and infrastructure teams to ensure flawless execution. Previously, as Solution Architect and Project Manager at Emerico, I spearheaded backend development for the ADCB Smart Banking Kiosks — delivering end-to-end project lifecycle management for high-stakes banking infrastructure.

My technical foundation spans PHP, Laravel, C#, and .NET, backed by scalable infrastructure on Docker and AWS. I strictly enforce PCI-DSS compliance, champion automated GitLab CI/CD pipelines, and introduced Selenium-driven QA automation directly within CI/CD workflows. I continuously integrate AI-assisted development tools and explore emerging technologies such as the Model Context Protocol (MCP) to push operational efficiency in financial services.
