• Developed responsive front-end interfaces and reusable components using Angular, React, and Blazor, reducing reliance on separate JS frontends for internal applications.
• Implemented enterprise authentication and authorization using Microsoft Entra ID (Azure AD), OAuth 2.0, OpenID Connect, and JWT, applying OWASP secure coding standards across 20+ applications.
• Containerized microservices with Docker and deployed to Azure Kubernetes Service (AKS) with rolling deployments, health probes, and autoscaling.
• Automated Infrastructure as Code (IaC) provisioning with Terraform and maintained Azure DevOps CI/CD pipelines, cutting release cycle time to as little as 3 hours.
• Improved application resiliency through centralized exception handling, retry policies, health monitoring, and distributed tracing, reducing recurring production incidents by approximately 25%.
• Developed comprehensive unit and integration testing suites using xUnit, NUnit, and Moq as part of a Test-Driven Development (TDD) approach, increasing code coverage to 85%+.
• Automated 95% of manual ticket triage by deploying an Azure OpenAI chatbot that autonomously classifies 30K monthly requests.
• Built a Retrieval-Augmented Generation (RAG) server that chunks and indexes 4M+ database records using Azure AI Search, enabling a customer-facing search and Q&A tool powered by Azure OpenAI.
• Designed and implemented multi-agent orchestration workflows for the Ask AT&T platform using Microsoft Semantic Kernel, LangChain, LangGraph, Azure OpenAI, and Azure AI Search, enabling intelligent task automation across enterprise workflows.
• Built reusable.NET 8 API wrappers, native plugins, and tool connectors integrating Azure OpenAI, Anthropic Claude, and open-source LLMs, accelerating AI adoption across business units.
• Built a Generative AI proof-of-concept on Amazon Bedrock, evaluating foundation models (Anthropic Claude, Amazon Titan) via the Bedrock Runtime API and applying Bedrock Guardrails for responsible-AI controls, as an exploratory alternative to the Azure OpenAI stack.
• Built ML-based detection models using ML.NET to identify and classify critical PIM (Passive Intermodulation) category tickets across Ericsson and Nokia network equipment, enabling proactive fault detection for AT&T's mobility network operations team.
• Mentored junior/mid-level engineers on Clean Architecture, CQRS, and AI integration patterns; led code reviews and design reviews adopted team-wide.
