About Me

From healthcare to tech, my journey as a developer began with a passion for solving real-world problems. Now, as a Senior Software Engineer, I architect cross-platform mobile experiences and robust backend systems that power apps used by thousands.

I thrive in the space where technical excellence meets human-centered design, crafting solutions that are both powerful under the hood and intuitive at the surface.
