Intro

Hi there, let me introduce myself. I'm a passionate backend developer who loves nothing more than creating efficient and scalable systems that solve complex problems. My strong foundation in Python and intermediate knowledge of Linux and scripting allow me to approach every project with a unique perspective, finding the best solution for the task at hand. But that's not all. I'm also skilled in database schema design and system designing at both low and high levels. And I'm well-versed in object-oriented programming, API design, and web development. In fact, I've even got experience in blockchain development and exposure to relevant languages like Solidity, Vyper, and Pact. That means I can create secure and peer-to-peer file transactions on both private and public networks. Plus, I've got experience in machine learning and AI, which has led to the development of services based on pre-trained models. Through various internships and projects, I've honed my skills in version control, testing, and debugging. I'm able to design and implement efficient backend and database schemas, making me a valuable addition to any team. And with my appetite for learning and staying up-to-date with the latest technologies, I'm constantly pushing the boundaries of what's possible. So if you're looking for a skilled and motivated backend developer who's always ready to take on a challenge, look no further. I'm excited to bring my expertise and passion to your team.
