About Me

Working on a project

My Journey

I'm a passionate Software Engineer with a keen interest in microservices, finance and robust backends. My journey in tech started when I built my first website in react at the age of 18, and since then, I've been on an exciting path of continuous learning and growth.

With a background in computer science and years of industry experience, I've had the opportunity to work on diverse projects ranging from small mobile applications to large-scale legacy enterprise applications.

Collaborating with team

What I Do

I specialize in building performant and scalable and financial applications using technologies like .NET, Docker, Terraform and SQL. My approach to development is centered around creating clean, maintainable code and delivering exceptional user experiences.

Beyond coding, I'm passionate about frisbee-golf and climbing. These activities not only keep me active and healthy but also help me stay focused and motivated in my work.

Let's Create Something Amazing

I'm always excited to take on new challenges and collaborate on innovative projects. Whether you have a specific project in mind or just want to explore possibilities, I'd love to hear from you.
