Design and implement authentication and authorization solutions using OAuth 2.0, OpenID Connect (OIDC), JWT bearer tokens, claims-based authorization, RBAC, and enterprise identity providers such as Microsoft Entra ID.
Develop and maintain microservices-based applications with a focus on resiliency, security, performance, observability, and scalability.
Implement API management capabilities using Apigee, including gateway integration, traffic management, security policies, and API governance.
Design, develop, and optimize database solutions, SQL queries, and stored procedures to support high-volume transactional systems.
Participating in Agile ceremonies including sprint planning, backlog refinement, design reviews, code reviews, and retrospectives.

Experience mentoring developers and contributing to architecture and technical design decisions.
Experience working within highly regulated financial services environments.
