Developed and enhanced a critical healthcare Practitioner Portal using [contact hidden], C#, and WCF services, supporting secure access to sensitive practitioner data. Contributed to the design and development of a new client onboarding UI using Angular and microservices architecture, gaining hands-on experience with large-scale distributed systems. Owned critical application components and ensured stability, performance, and adherence to healthcare compliance requirements.

CQRS Microservices Architecture: Led the decomposition of legacy monolithic banking services into high-performance, distributed microservices using CQRS (Command Query Responsibility Segregation) design patterns inside [contact hidden] Core and Azure containerized landscape. Throughput Improvements: Isolated read-heavy transactional queries from write-heavy command mutations using targeted Azure SQL read-replicas, boosting aggregate data throughput by 30% for complex consumer accounts. Business Translation & Mentorship: Translated intricate financial policy documentation into scalable domain service modules using Domain-Driven Design (DDD). I also mentored 4 junior engineers on Clean Code architectures and advanced asynchronous C# paradigms.

Scale Optimization: Engineered and optimized core e-commerce cart functionalities for [contact hidden], successfully scaling backend services to sustain traffic peaks exceeding 35M+ monthly active users. MFE Shadow DOM Styles Fix: Resolved critical design system breakdowns across Micro Frontends (MFE) by orchestrating a dynamic injection system that registers global style payloads directly to the host document.head. This bypasses strict encapsulation boundaries and maintains cross-cart visual uniformity. State & Lifecycle Sync: Eliminated cart loading race conditions and UI freezing states by capturing deep browser-level rendering events and explicitly mapping them directly into MFE component initialization lifecycle hooks. CI/CD Pipeline Automation: Architected a dynamic test-data seeding framework within xUnit test configurations to address recurring CI/CD failures caused by mock-to-production data drifts. This fix saved approximately 15 engineering hours per week of downtime for a 6-developer team.
