Need a developer to build a business web application, extend an existing system, or connect your software through APIs? I’m a full-stack software engineer with 10+ years of experience across business applications, CRM systems, CMS websites, and ISP management software. My core technologies include .NET Core, ASP.NET, Next.js, NestJS, and SQL databases. My Upwork track record includes $20K+ earned. My portfolio includes a Next.js/NestJS ISP management platform, custom DNN modules, and CMS development and customization. I can help with: • Full-stack web application development • Features, fixes, and improvements for existing applications • REST API development and third-party integrations • SQL Server, PostgreSQL, and MySQL database development • DNN and Kentico development and customization • AWS application deployment For each engagement, I will agree on scope, milestones, communication hours, and progress updates before development begins. My focus is maintainable code and a clear handover. Send me a brief description of your application, its current technology stack, and the main problem you want to solve. We can then define a practical first milestone.
