Kartik Vats | Software Development Engineer

About

Software Engineer with 4 years of experience designing, building, and shipping production applications across mobile and web. Alongside core systems and architecture, I bring a keen eye for UI/UX design—crafting interfaces with attention to typography, spacing, and micro-interactions that feel natural to use.

I handle the complete development and release lifecycle, including system architecture, UI engineering, App Store and Google Play review compliance, In-App Purchases, and CI/CD pipelines. Focused on clean code, aesthetic precision, and reliable performance.
