Senior Software Engineer - Dayforce Wallet - Alpharetta, GA
(2019-08 - 2026-03)
- Led development and contributed to architecture for key Azure-based microservices and web applications supporting digital wallet, payment, and high-volume transaction platforms.
- Built backend services for real-time transaction processing similar to ecommerce checkout and payment workflows.
- Developed modern React-based user interfaces using JavaScript, HTML, and CSS for portal and operational workflows.
- Rewrote a slow reconciliation engine handling about 300,000 transactions by replacing repeated LINQ joins with fast in-memory dictionary lookup tables, reducing runtime from about 10 minutes to about 10 seconds and eliminating browser timeout issues.
- Refactored three separate reconciliation solutions - Tips, On Demand Pay, and Direct To Bank - into a unified generic-based architecture with shared repositories and services, dramatically reducing duplicate code and simplifying future enhancements.
- Added comprehensive unit test coverage to the modularized reconciliation framework, improving reliability and deployment confidence.
- Designed and implemented a 125-worker parallel background-processing model to improve throughput for high-volume processing scenarios.
- Improved portal lookup responsiveness with an adaptive Fast Retry approach that retried slow profile lookups quickly before backing off, reducing common operator waits from roughly 30 seconds to roughly 3-5 seconds.
- Upgraded services to use EF with Azure AD token interception and optimized database access patterns, improving SQL connection reliability and performance.
- Developed and tuned SQL Server queries and data access layers for transaction-intensive systems.
- Mentored a junior developer/intern for approximately two years and reinforced coding standards, modular design, and maintainable engineering practices.
