• Distributed Microservices Modernization: Architected microservices with .NET 8 and serverless Azure Functions, orchestrating zero-downtime data migrations from legacy CosmosDB stores into highly indexed SQL Server instances[cite: 1].
• Real-Time Decoupled Frontends: Overhauled old frontend patterns to isolated, fast single-page applications (SPAs) running Vite, React 19, and TypeScript, managing continuous real-time state sync via SignalR pipelines[cite: 1].
• Monolithic Deconstruction: Transformed traditional, platform-dependent Windows .NET Framework monolithic architectures into optimized Linux containers via Docker and Kubernetes pools, dropping deployment provisioning times by 60%–80% using automated Azure DevOps workflows[cite: 1].
• Technical Team Leadership: Directed Agile engineering sprints for squads of 5–6 cross-functional developers, establishing declarative code-review structures, uniform testing automations, and third-party enterprise integrations (Stripe, Shopify)[cite: 1].
