Architecting High-Throughput
Distributed Systems & AI Workflows

Delivered full-stack retail eCommerce Cart and Checkout experiences powering dell.com across 100+ countries within Dell's Pivotal Cloud Foundry (PCF) ecosystem (~70% backend .NET in first two years; ~70% frontend Angular 14–16 in final two years). Impacted by a corporate workforce reduction in September 2026, concluding tenure as a top-rated engineer.

• Full-Stack Architecture & Scale: Delivered end-to-end features combining high-throughput .NET Core 6/8 microservices with responsive Angular (v14–v16) single-page applications handling millions of daily global shopping sessions.
• Angular Modernization & Reactive Architecture: Personally migrated checkout frontends from Angular 14 to 15 (MDC components & standalone APIs); built reusable component libraries using RxJS observables, strict unsubscription hygiene, and NgRx state synchronization.
• Frontend Testing & SLAs: Authored 180+ Karma/Jasmine unit tests (88% code coverage) and Playwright E2E suites verifying sub-300ms interactive response times; linked SPAs to .NET APIs via automated OAuth 2.0 / JWT token interceptors.
• Distributed Caching & Queuing: Designed multi-tier dynamic Redis caching strategies with RabbitMQ and Kafka event streaming, eliminating database hotspots during peak Black Friday / seasonal surges.
• Telemetry & P99 Latency: Ingested telemetry across Lighthouse, Boomerang (RUM), Splunk, and Dynatrace; applied statistical data science models to eliminate Cart TTL regressions and stabilize sub-second P99 latencies.
• Mentorship & AI-Augmented Engineering: Mentored junior engineers via daily code reviews on SOLID, RxJS, and clean architecture; leveraged GitHub Copilot with strict Human-in-the-Loop review and zero-PII prompt guardrails.

Directed software architecture and engineering delivery for TechShare judicial and court management enterprise platforms for the Texas Conference of Urban Counties.

• Architected distributed web applications in .NET Framework MVC/Razor and .NET Core WebAPI with React frontends, integrated with Azure SQL and Entity Framework Core.
• Implemented Azure Blob Storage, Redis caching, and Docker containerization to maintain high availability under massive court filing surges.
• Automated CI/CD build and deployment pipelines via TeamCity and Octopus Deploy, establishing zero-downtime releases.

Modernized Dell's global Customer Integration Layer (CIL) gateway from legacy WCF SOAP to high-performance .NET Core 3.0 RESTful APIs.

• Maintained backwards compatibility and 99.99% availability for an enterprise integration gateway consumed by 25+ internal and external Dell client applications globally.
• Spearheaded enterprise migration of source control and pipelines from TFS and Octopus to GitLab Pipelines and Cloud Foundry (PCF).
• Authored complex Oracle DB stored procedures and integrated cross-platform data pipelines across SAP, Oracle, MySQL, and NoSQL stores.

Architected and built high-volume .NET Core RESTful microservices for PG&E Wildfire Safety and Emergency Decision Support Systems.

• Engineered multi-threaded asynchronous C# solutions to ingest, transform, and serve geospatial and telemetry data simultaneously from Google Maps APIs, relational databases, and Redis caches.
• Authored optimized MongoDB Aggregation pipelines and PostgreSQL stored procedures, executing seamless enterprise migration from MongoDB 3.4 to 4.0.
• Implemented secure API access protocols adhering to OAuth, JWT Token, and enterprise SSO standards.

Directed .NET middleware architecture and delivery for CEMEX GO global digital transformation platform across 21 countries.

• 95% Latency Reduction: Slashed Point of Delivery (POD) summary API response latency from 12 seconds to under 500ms by engineering a custom Redis caching middleware layer.
• Designed and exposed scalable RESTful APIs using C#, ASP.NET Web API v2, Entity Framework, and Azure API Management for Android, iOS, web, and enterprise B2B clients.
• Refactored SQL Server indexing strategies, execution plans, and stored procedures to eliminate high-volume database deadlocks.
• Led international technical enablement missions to Czech Republic and Hungary, onboarding regional teams and authoring technical documentation for IBM Tier 2/3 support.
