Architecture, Leadership, and Quality

• Led end-to-end solution design by translating business requirements into scalable, domain-driven architectures.
• Collaborated with architects, business analysts, and engineering teams to define technical roadmaps and implementation standards.
• Established and enforced code quality standards using pull request reviews and static analysis, reducing technical debt.
• Achieved defect density of less than 0.5 defects per 1,000 LOC , and defect leakage of less than 3%.

Back-End Architecture, Performance, and Resilience .

• Designed and implemented .NET Core microservices using layered and Service-Oriented Architecture (PL, DSL, BLL, DAL).
• Defined REST-based synchronous communication and asynchronous processing using EESB Messaging (Queues and Topics) .
• Improved P95 latency by 15% using async/await , parallel processing , distributed caching ( Redis/Memory Cache ), and Entity Framework Core optimization.
• Implemented resiliency patterns, including Circuit Breaker, Retry with backoff, and Dead Letter Queues (DLQ).
• Designed monitoring solutions based on Golden Signals to proactively detect performance and reliability issues.
• Architected systems supporting 1,000+ concurrent users , with high availability and throughput.

Front-End Architecture (Angular)

• Led the development of Angular-based Client Portal and TrF applications from scratch.
• Designed dynamic, user-configurable UI components , and a JSON-driven form engine.
• Maintained approximately 85% code coverage across critical Angular components to minimize regression risk.

Security and Identity

• Architected dual-authentication solutions, integrating Azure AD B2C for external users, and Entra ID/FAMS for internal users.
• Secured .NET Core microservices using JWT-based authentication and authorization.

DevOps and Delivery Governance .

• Architected and implemented end-to-end Azure DevOps CI/CD pipelines for IaaS and PaaS environments.
• Automated build, test, and deployment workflows to improve delivery reliability.
• Reduced development cycle time by 25% while sustaining a sprint velocity of 40+ story points.
