A Windows desktop downloader and network monitor that brings selected internet connections together for one file, with resumable transfers, browser handoff, and a local MCP server for AI tools.
I’m Rajesh Kumar, a Python developer based in Coimbatore, India. My work spans backend services, full-stack applications, and the connections between them.
Good software starts with understanding the problem. Then making the moving parts work together.
My growth comes from building: independent projects, live applications, and the problems that emerge when people actually use them. I work across APIs, interfaces, data, and deployment to connect the whole system.
Professional experience strengthened my foundations. I keep expanding them through hands-on development, new tools, and my studies in AI and machine learning.
