Hands-on experience developing in client/server environments with technologies such as ASP.NET, MVC, Entity Framework, ADO.NET, Web Services (SOAP, WSDL, UDDI), Web APIs, and JSON.
Experience with UI and presentation-layer development using HTML, CSS, JavaScript, jQuery, DHTML, XML, and related tools.
Strong understanding of SDLC, Object-Oriented Programming, and methodologies such as Agile/SCRUM.
Proven ability to gather requirements, prepare use cases, and interact with end users and stakeholders.
Experience with UML diagrams, component development, and event-driven programming.
Excellent communication, problem-solving, and adaptability skills with the ability to collaborate across teams.
