What I'm looking for
John Brancaleon is a highly accomplished Senior Software Developer with over four decades of programming experience, specializing in enterprise-level solutions built on the Microsoft technology stack. Throughout his career, John has consistently delivered scalable, high-performance applications by leveraging C#, .NET Core, Blazor, ASP.NET MVC, Entity Framework, and SQL Server. He has extensive experience integrating Telerik UI components, developing RESTful APIs, and optimizing database performance through advanced query design and stored procedures. John’s work has spanned industries including financial services, healthcare, and manufacturing, giving him a broad perspective on regulated environments and mission-critical systems.
In addition to his deep technical expertise, John has excelled in leadership and mentorship roles, guiding junior developers and collaborating with business stakeholders to translate requirements into practical, effective solutions.

Today, John is expanding his expertise into the rapidly evolving field of artificial intelligence, with a focus on AI-assisted development and prompt engineering. He is building a portfolio of projects that explore how large language models can be guided through structured prompting to clean and transform data, generate domain-specific content, and automate workflows. By combining his mastery of software engineering with emerging AI practices, John is positioning himself at the forefront of technology innovation—bridging the gap between traditional enterprise systems and the next generation of intelligent applications
