Summary
👤
Senior🎓
Top SchoolDavid Maclay is a backend-focused technical lead with 15+ years building scalable microservices and cloud-native architectures across AWS, Azure, and self-hosted environments. He combines hands-on coding in Python and Go with systems-level ownership, having architected payment, reconciliation and tax automation pipelines that handle billions in cash flow and multi-state VAT filings. Known for refactoring legacy async systems and accelerating data retrieval (up to 40x in one finance dashboard), he also optimizes CI/CD and integrates privacy-conscious open-source tooling. His work spans end-to-end delivery—from OAuth-enabled ETL for Amazon Marketplace data and state-specific Excel exporters to electronic filing encoders and SharePoint syncs—demonstrating both domain depth in payments/tax and pragmatic product thinking. As a cross-team technical lead he has negotiated third-party integrations and driven compliance automation while mentoring engineers across regions. Based in Ireland, he brings a rare blend of financial systems expertise, operational SRE experience, and a knack for turning messy transactional data into auditable, production-ready workflows.
