Integration, APIs, and Middleware

- Integrated identity and access management using Okta; enforced secure API access, token-based authentication, and role-based authorization for enterprise applications.

- Designed and built RESTful and SOAP services (Apache Axis) with robust error handling, versioning, and backward compatibility strategies.

- Expert in enterprise integration architecture and patterns, including orchestration, choreography, and message-driven designs.

Observability, Reliability, and Operations

- Designed and maintained Splunk dashboards and alerting for application and infrastructure observability; implemented operational monitoring and incident response workflows.

- Created numerous Splunk alerts (including for Mastercard BizOps) to proactively detect anomalies, performance issues, and security events.

- Led production triage (TRT) and L2/L3 support; coordinated cross-team incident resolution, root-cause analysis, and corrective actions.

- Supported go-live activities across multiple applications; managed changes, deployments, and post-release stabilization.

- Analyzed performance issues; tested, maintained, and monitored distributed applications to ensure reliability and service levels.

Delivery Process, Quality, and Documentation

- Demonstrated understanding of Agile development and DevOps practices; contributed to backlog grooming, sprint planning, reviews, and retrospectives.

- Prepared detailed workflow charts and diagrams describing inputs, outputs, and logical operations for systems and integrations.

- Drafted and updated process documentation, runbooks, and operational guides; standardized change requests and server configurations for critical applications (e.g., Master Pass).

- Coordinated and facilitated cross-functional meetings to gather requirements from clients, align priorities, and unblock delivery.

Security, Scalability, and Performance

- Applied security-by-design principles including least privilege, encryption in transit/at rest, secrets management, and policy enforcement.

- Optimized system performance through caching, connection pooling, indexing, and code-level improvements; implemented scalable patterns for high-concurrency workloads.

- Ensured non-functional requirements (NFRs)—availability, reliability, throughput, latency—were met through rigorous testing and architecture reviews.

Leadership and Communication

- Led DevOps and SRE initiatives to improve release cadence, reduce incidents, and enhance observability across applications.

- Collaborated effectively across engineering, product, operations, and compliance teams; communicated complex technical concepts clearly to diverse audiences.

- Strong presentation, facilitation, negotiation, and influencing skills; able to drive consensus and deliver outcomes.
