If your .NET system is slow, unstable, hard to maintain, or blocking business growth - I fix that. I help businesses rescue, modernize, and scale legacy .NET applications without disrupting ongoing operations. Let’s discuss your project today — I’ll review your current setup free of cost and suggest a practical, scalable plan before we even start. Most of my clients reach out when: - Their legacy system is crashing, slow, or insecure - Developers left and nobody understands the code - Compliance audits (HIPAA / PCI-DSS) are failing - The system can’t scale with users or business demand - They want to modernize without a risky full rewrite With 8+ years of experience, I’ve helped companies in Healthcare, FinTech, ERP, POS, and HRMS turn fragile legacy systems into secure, cloud-ready platforms used by thousands of users daily. ✅ What I Can Do for You - Stabilize and refactor legacy .NET / ASP .NET applications - Modernize WebForms or MVC apps into clean, scalable architectures - Migrate systems to .NET Core / .NET 6–8 and Azure - Fix performance bottlenecks and security vulnerabilities - Design compliance-ready systems (HIPAA, PCI-DSS, HL7/FHIR) - Build new systems the right way using Clean Architecture I have worked on various projects for clients across different industries and sectors, delivering solutions that meet their needs and expectations. I have a strong knowledge of Sitecore architecture, features, modules, tools, and APIs, as well as other web development technologies such as .NET (MVC),.Net Core, C#, HTML, CSS,bootstrap,DevExpress,Angular,Jquery, JavaScript, SQL Server, React, Next.js, etc. Why work with me? 💕Reliable & Accountable -- Consistently deliver on commitments, meet deadlines, and maintain a high standard of work. 💕Strong Technical Breadth & Depth -- Experienced with modern frameworks (React/Next.js, Node.js/.NET), scalable APIs, and both SQL/NoSQL databases. 💕Clean, Maintainable Code -- Focus on clarity, modular structure, and long-term maintainability. 💕Problem-Solving Mindset -- Able to diagnose issues quickly and implement efficient, effective solutions. 💕Collaborative & Communicative -- Work effectively with cross-functional teams and communicate clearly with technical and non-technical stakeholders. 💕Fast Learner & Adaptable -- Stay current with new technologies and best practices to keep systems modern. #DotNet #SeniorDeveloper #ASPNetMVC #AngularJS #EntityFramework #SQL #MySQL #API #ArtificialIntelligence #WindowsForms #DevExpress #SSRS #SAPCrystalReports #GitScrum #Jira #Trello #AndroidThings #iOS #WebDevelopment #DesktopApplications #FullStackDeveloper
