Available to hire
Hi there! I’m Wattakamol Lanjakornkul, an iOS-focused developer with over five years of hands-on experience building mobile apps that ship. I specialize in Swift and Objective-C, and I’ve delivered high-quality solutions for startups and enterprise teams in Thailand, collaborating across product, design, and QA to turn ideas into polished apps.
I enjoy learning and applying new technologies, keep up with modern architecture patterns like MVVM, and am comfortable with GitHub, CI/CD pipelines, and automation tools. I’m also exploring Flutter and cross-platform approaches to broaden the impact of my work while staying focused on delivering robust iOS experiences.
