Technical Lead I / Lead Solutions Architect

January 2025 – Present

Key Project: Real-Time Vehicle Import Processing Platform

  • Led end-to-end architecture of a cloud-native, real-time vehicle import platform ingesting and processing 11,000+ vehicles per import with near-real-time user feedback and full observability.
  • Designed an event-driven pipeline using Azure Functions (Blob Trigger) to process large inbound vehicle files from Azure Blob Storage in real time.
  • Orchestrated asynchronous workflows via Azure Service Bus for scalable, fault-tolerant processing across downstream services.
  • Implemented full lifecycle event auditing and traceability using Azure Event Hubs for compliance and operational analysis.
  • Delivered real-time user notifications via Azure Web PubSub, powering live status updates in a React-based admin dashboard.
  • Centralized business rules in a single-source-of-truth Azure Container App, ensuring consistency across all ingestion flows.
  • Secured all APIs using Azure API Management (APIM) — enforcing OAuth2, rate limiting, and threat protection across all platform endpoints.
  • Protected the React admin portal using Azure Front Door — WAF policies, SSL termination, and DDoS protection at the edge.
  • Persisted transactional data in Azure Cosmos DB with Azure Redis Cache for high-speed state tracking.
  • Built a React.js admin portal to manage imports, monitor processing stages, and troubleshoot failures in real time.
  • Integrated SendGrid (email) and Twilio (SMS) for proactive operational alerting.
  • Enabled end-to-end observability via Azure Application Insights with distributed tracing, custom metrics, and alerting.

Environment: Azure Functions, Service Bus, Event Hubs, Web PubSub, Container Apps, Cosmos DB, Redis Cache, Blob Storage, APIM, Front Door, Application Insights, React.js, SendGrid, Twilio, .NET 8, C#

Key Project: GraphQL API Gateway for Remarketing Solutions

  • Led architecture of a unified GraphQL server (HotChocolate/.NET) to replace 150+ fragmented REST GET endpoints, delivering a single, flexible data retrieval interface for the Remarketing Solutions platform.
  • Eliminated API sprawl by consolidating all read operations into one schema-driven GraphQL API, reducing over-fetching and under-fetching and simplifying frontend workflows.
  • Designed the GraphQL layer as a federation-ready aggregation service, resolving data from multiple downstream microservices through a single query surface.
  • Secured the GraphQL endpoint via Azure API Management (APIM), enforcing OAuth2 authentication, query-depth limiting, rate throttling, and threat protection.
  • Enabled fine-grained field-level access control through GraphQL directives, ensuring consumers only retrieve data within their authorization scope.

Environment: GraphQL (HotChocolate), ASP.NET Core, Azure API Management (APIM), Azure Container Apps, .NET 8, C#, Azure Application Insights
