About

I am a Full Stack Engineer specializing in Agentic AI and AI-driven software development, with 4+ years of experience building enterprise applications.

My journey began with backend engineering, where I built scalable applications using .NET, C#, microservices, and modern software architecture. Over the past two years, my focus has increasingly shifted toward Generative AI, intelligent agents, and AI-powered software engineering.

At In Time Tec, I developed enterprise applications using AI-assisted and agent-driven approaches, including the Idaho Digital Learning Alliance (IDLA) platform, which I built end to end using AI agents.

Today, at Optum, I focus on AI-Driven Development Lifecycle (AIDLC), integrating AI platforms and intelligent workflows into the software engineering process.

I bring together strong engineering fundamentals and AI-driven development to build scalable software, streamline engineering workflows, and improve developer productivity.

Idaho Digital Learning Alliance (IDLA)

End-to-End Application Development with AI Agents

.NET 10ReactAI AgentsEF CoreSQL ServerAWSRedis

Project Overview

Modernized the Idaho Digital Learning Alliance (IDLA) platform by migrating legacy MVC business logic into a decoupled architecture built with .NET 10 Web API and React.

The application was developed end to end using AI agents and AI-powered development tools, with engineering oversight across architecture, implementation, and validation.

Engineering Contributions

AI-Agent-Driven Development

  • ▸Leveraged AI agents throughout the development process to support application implementation and iterative refinement.
  • ▸Combined AI-driven code generation with engineering review and validation.

Application Modernization

  • ▸Migrated legacy MVC business logic into a scalable .NET 10 Web API and React architecture.
  • ▸Designed a decoupled application structure to support maintainability and scalability.

Authentication & Security

  • ▸Developed IDLA.Auth, a centralized authentication service supporting OAuth 2.0 with Google and Microsoft, along with JWT-based authentication.

Data & Infrastructure

  • ▸Optimized data access using EF Core, the Repository Pattern, and stored procedures.
  • ▸Integrated AWS Secrets Manager and Redis distributed caching.
  • ▸Applied FluentValidation, Serilog, and StyleCop to support code quality and maintainability.

Engineering Focus: Agentic AI development, enterprise application modernization, secure authentication, backend architecture, and AI-assisted software delivery.
