Hi there, I am a strong fit for this project because I have built secure, browser-based coding tools that execute multiple languages reliably. I have experience implementing online compilers for Python, JavaScript, and C++, including sandboxed execution and clear error reporting. I work with modern web editors for syntax highlighting and autocompletion, secure backend runners, and standard authentication flows. I reduce risk by isolating code execution, enforcing resource limits, and validating outputs and errors consistently across languages. I am available to start immediately and can deliver a clean, demo-ready online compiler with clear setup instructions. Regards Chirag
