I design and build business systems—from domain requirements and cloud architecture to engineering execution and production delivery.
Business domains, system boundaries, integrations and AWS infrastructure.
Technical direction, team practices, vendor review and delivery.
Backend engineering, cloud operations and full-stack implementation.
Building a greenfield platform for subscriptions, recycling, logistics, loyalty and merchant redemption with a lean engineering team.
Explore the case study →Designing ecohope-workspace across 14 active repositories: shared context, isolated workspaces and human approval throughout delivery.
Explore the workflow →Technical design and major development of a multi-storefront commerce module, integrated with shared identity, loyalty, payment and notification services.
Explore commerce architecture →Architecture, system-design and business-use-case support alongside dedicated project managers, analysts and development teams.
Explore my contribution →At EcoHope, uncertain early traffic made low idle cost important. Serverless compute supported this while retaining room for growth. This also meant accounting for database connections, asynchronous work and release coordination.
I begin with business rules, workflows and data ownership, then decide how application and integration boundaries should support them.
Shared architectural context, requirement clarification, approved plans, local testing and human review are part of the development workflow.
My career has progressed from programming to system analysis, architecture and technology leadership. E-commerce and logistics remain central to how I understand business systems.
