I'm an engineer with more than a decade of experience in software development. I started my career in startups working as a full-stack and backend developer. I gained valuable experience in building robust and scalable systems during that time.

Three years ago, I joined Via as a backend engineer. Since then, I've moved up the ranks to become a tech lead and then a software architect. As a software architect, I design and implement complex software systems that meet the needs of our clients.

I love coding and enjoy participating in hackathons and meetups. It's a great way to stay up-to-date with the latest trends in the industry. My favorite language is Python, and I'm particularly enthusiastic about serverless architectures. I'm always seeking new ways to optimize and streamline my code.

In addition to my technical skills, I'm an effective communicator and team player. I enjoy collaborating with colleagues and clients to deliver high-quality software solutions. I'm driven by a passion for innovation and a desire to push the boundaries of what is possible in the field of software engineering.
