Who I Am

Sean Pesis
<FullStack />
B.Sc. CS 🎓

Hey! I'm Sean Pesis, a Full-Stack Engineer with a freshly earned B.Sc. in Computer Science. I love building things that are not just functional, but beautifully engineered.

From real-time distributed systems to polished web apps, I enjoy tackling complex challenges with clean, scalable solutions. My background spans backend architecture, cloud infrastructure, mobile development, computer vision, and cybersecurity.

When I'm not coding I'm exploring new tech, building side projects, and always looking for the next interesting problem to solve.
