Full Stack Dev - C#, .NET, Azure, Vue, LLM and AI Engineer

With over 20 years of development experience, I build robust, scalable applications that solve real business problems - and I now bring an AI-first approach to both how I work and what I build. My expertise centers on the .NET ecosystem (C#/.NET Core, ASP.NET Core, Entity Framework Core), backed by a full-stack perspective and cloud deployment on Azure. What I bring to your project: AI-Powered Development: I leverage modern AI tooling (Claude Code, Cursor, GitHub Copilot) to ship higher-quality code faster, meaning shorter timelines and lower cost for you, without compromising on architecture or maintainability. Building Intelligent Applications: I integrate AI and LLMs directly into products - from a computer-vision quoting platform that automated manual estimating, to Python applications that turn raw data into clear, narrative reports. If you want to add AI capabilities to a new or existing system, I can help you do it pragmatically. Backend Excellence: .NET Core APIs, Entity Framework, SQL Server, and Azure cloud deployment built for reliability and scale. Full-Stack Capability: From database design to clean, user-friendly interfaces with modern JavaScript (Vue.js). API & Integration Expertise: Building APIs for others to consume, or integrating existing services: payment processors, CRMs, analytics platforms, and third-party AI services. Recent work: I've modernized legacy systems for better performance and lower maintenance cost, automated manual workflows with AI and computer vision, and integrated complex third-party services...always focused on outcomes, not just code. Ready to talk? I take the time to understand your specific challenges and goals before proposing a solution. Let's discuss how I can help you achieve your objectives efficiently and within budget.
