Hello, I reviewed your requirements for the [login to view URL] and NestJS bot application. Before making any changes, I always study the existing codebase first, the frontend structure, backend APIs, and bot workflow, so I understand exactly how everything connects and avoid breaking what already works. Once I have that clarity, I can add the new features you need, improve the UI responsiveness, fix existing bugs, and optimize slow queries or API calls. I am comfortable working with PostgreSQL, MySQL, or MongoDB, and handling authentication with JWT, roles, and permissions properly. For third party integrations, I will make sure everything is tested with real edge cases, not just the basic flow, so the bot behaves reliably once live. After testing, I can deploy to your server using Docker and share simple documentation covering what was changed. I have solid hands on experience with [login to view URL], NestJS, and TypeScript across full stack projects, some of which are on my portfolio and GitHub below. Portfolio: [login to view URL] GitHub: [login to view URL] Happy to start once we align on the exact features and priorities.
