About

I am a technology leader with 20+ years of experience building scalable systems, cloud-native platforms, and high-throughput transaction flows. I excel at aligning C-level strategy with execution, mentoring engineering leaders, and delivering robust software that scales in complex environments.

My career highlights include driving Ebay-scale blogs and social platforms, migrating large-scale properties to AWS with SOA governance, and delivering high-impact products like GrabRewards in under 3 months. I thrive in data-driven, security-conscious settings and enjoy mentoring teams to ship reliable, secure systems while continuously improving engineering practices.
