Justin M.

With 20+ years of hands-on experience, I design and deliver software that not only works — it works reliably under pressure. From finance and healthcare to e-commerce and SaaS, I’ve built systems that had to run like clockwork, where downtime simply wasn’t an option.

I thrive in the Microsoft ecosystem. Whether it’s building bulletproof APIs in ASP.NET Core, modernizing legacy .NET Framework apps into sleek .NET 6/7+ solutions, standing up microservices on Azure and AWS, or integrating React front-ends with robust C# or Node.js backends, I bring the technical depth and discipline to keep projects moving forward.

I also specialize in AI/ML-driven solutions — integrating intelligent features into .NET and Node.js applications, from chatbots and recommendation engines to workflow automation powered by Azure Cognitive Services and OpenAI APIs.

👉 What I Can Do For You
➤ C# / .NET Development – Expert in all aspects of .NET: WinForms, WPF, VB.NET, Windows Services, ASP.NET Core (Web API, MVC, Blazor). Skilled in multi-threading, async/await, and SOLID design principles.
➤ Node.js Development – Build high-performance, event-driven services and APIs using Node.js, Express.js, and TypeScript. Skilled in creating real-time apps with WebSockets and integrating Node.js with .NET or cloud-native solutions for hybrid architectures.
➤ Backend & APIs – Architect and deploy secure RESTful APIs, consume third-party services, and integrate with payment processors, messaging platforms, AWS S3, and more. Swagger/OpenAPI included.
➤ Web Applications – Build or modernize applications with ASP.NET MVC, Razor, Blazor, and React. Experienced in connecting React/Angular front-ends to scalable .NET Core and Node.js APIs for smooth, user-friendly solutions.
➤ Database Engineering – SQL Server, PostgreSQL, MySQL. Schema design, Entity Framework, stored procedures, query optimization, and data migration between DBMS platforms.
➤ Cloud & DevOps – Deploy to Azure Functions, App Services, or AWS Lambda. Experienced with Docker, CI/CD (Azure DevOps, GitHub Actions), and source control (Git, SVN).
➤ AI & Machine Learning – Integrate AI-powered features into business apps: natural language processing, predictive analytics, chatbots, and recommendation systems. Skilled with Azure Cognitive Services, ML.NET, and OpenAI APIs.
➤ System Administration – Configure and manage Windows servers, migrate virtual machines (Hyper-V ⇄ ESXi), set up SQL Server replication (transactional or merge).

I bring the technical depth to untangle legacy systems, the versatility to deliver both .NET and Node.js backends, and the innovation to embed AI-driven intelligence into your applications. If you’re ready to take your project from “work in progress” to “mission accomplished,” I’m here to make it happen.
