What I'm looking for

I seek roles where I can lead integrations and architecture for logistics/eCommerce, work with cross-functional teams, and deliver scalable, cost-effective systems with opportunities for technical leadership and remote collaboration.

I am a results-driven Lead Software Engineer and Integration Specialist with over 15 years designing, developing and delivering complex enterprise solutions for shipping, logistics and payments. I have successfully integrated 20+ global carriers and multiple payment gateways, built scalable end-to-end systems, and led remote teams while acting as a trusted freelance partner for long-term client engagements.

My background spans carrier API and file-based integrations, payment gateway implementations, banking and POS systems, and cloud-native deployments using Docker and Kubernetes. I bring technical leadership, systems architecture, product and project management experience, and a pragmatic, cost-effective approach to solving logistics and eCommerce challenges.
