What I Bring

More than a developer. An engineering force.

I combine deep technical depth with product thinking and team leadership to build systems that matter at enterprise scale.

Architecture & API Orchestration

Designing scalable microservices, RESTful APIs, and event-driven pipelines that process millions of transactions with resilience and speed.

Enterprise Modernization

Migrating legacy platforms to .NET Core, cloud-native Azure, and automated CI/CD — across government, finance, and enterprise clients.

Performance & Scalability

Reducing latency 70%, cutting deployment times 94%, and architecting autoscaling infrastructure that handles 10K+ concurrent requests.

Cross-Functional Leadership

Leading distributed teams, aligning stakeholders, and driving complex delivery from architecture through production deployment.

Achievements

Impact, not just output

Measurable outcomes delivered across enterprise engagements — business value backed by real metrics.

United Airlines – Loyalty & Accrual Redemptions

Transformed Manual Booking into One-Click Automation

Engineered an Upgrade Manager API powering the Navigator system — converting multi-hour manual upgrade workflows into instant one-click operations, drastically improving agent efficiency and customer turnaround time.

United Airlines – Loyalty & Accrual Redemptions

Cut Deployment Time by 94%

Built Azure DevOps CI/CD pipelines with blue-green deployments — reducing release time from 4 hours to 15 minutes with zero-downtime production deployments.

United Airlines – Loyalty & Accrual Redemptions

Reduced MTTR by 60% & API Latency by 70%

Configured Kibana and Dynatrace monitoring and implemented Redis caching for loyalty services — improving observability, reducing incident resolution time, and accelerating API performance.

New Jersey Treasury – Claims Modernization

Accelerated State Claim Processing Modernization

Led modernization of legacy claims platforms to .NET Core and Azure — improving reliability, security, and processing efficiency for high-volume government workflows.

Experience

Project timeline

6 enterprise engagements across loyalty, government, airline, mortgage, and technology.

Key Responsibilities

Developed RESTful APIs using C# .NET 6, ASP.NET Core 6.0, and Entity Framework Core 6 to manage MileagePlus miles, Plus Points, and Chase Cash loyalty currencies.

Engineered automated workflows integrated with the Navigator agent-facing application that converted multi-hour manual booking processes into instant one-click operations.

Implemented loyalty point calculation algorithms based on MileagePlus tiers (Premier Silver, Gold, Platinum, 1K), flight classes, distance, and promotional multipliers.

Built microservices using .NET Core 6.0 with Docker 20.10 and Kubernetes 1.24, configuring horizontal pod autoscaling to handle 10,000+ concurrent requests during peak periods.

Implemented Redis 6.2 caching layer and RabbitMQ 3.11 message queues — improving API response times by 70% and handling millions of asynchronous loyalty accrual events.

Built Azure DevOps CI/CD pipelines with automated testing and blue-green deployments, cutting release time from 4 hours to 15 minutes with zero-downtime deployments.

Secured APIs with OAuth 2.0, JWT authentication, RBAC, and PCI DSS-compliant data encryption for Chase credit card payment system integration.

Built React 18 UI with TypeScript 4.9 and Redux Toolkit for agent dashboards with real-time loyalty balances, transaction histories, and redemption options.
