    Hi!! Want your website to run smoothly with minimal bugs so you can focus on growing your business instead of handling technical details? If that sounds familiar, you're not alone. From my work with startups and small businesses, I've seen that delivering new features quickly depends on having team members who can manage both frontend and backend tasks. Having a reliable person for both sides is essential. As a full stack developer, I use Python with Django for the backend and React with TypeScript for the frontend. I’ve worked with remote teams on projects ranging from e-commerce sites to CRM systems and OpenAI chatbots. If you need your first hire or some extra help to move your project forward, I’d love to assist!
