    Who I Am

    Hi, I'm Sueksit Vachirakumthorn, a 24-year-old Full-Stack Developer from Thailand. I'm passionate about building efficient, scalable web and mobile applications that people actually enjoy using.

    I code with purpose, learn with curiosity, and always aim to ship clean, maintainable solutions. Whether it's crafting pixel-perfect frontend experiences or architecting robust backend systems, I believe in building technology that makes a difference.

    What Drives Me

    Clean, maintainable code — I build for today and tomorrow, ensuring code quality that scales with projects and teams.

    Real-world problem solving — I love creating applications that are helpful, usable, and meaningful to users.

    Continuous learning — Technology evolves fast, and I'm always exploring new tools, frameworks, and best practices.

    Collaboration & teamwork — Great products come from great teams, clear communication, and shared vision.

    My Journey

    Having completed my Computer Engineering degree at King Mongkut's University of Technology Thonburi (KMUTT), I built my expertise through hands-on projects, internships, and real-world applications throughout my studies.

    Through leading full-stack development projects and various technical roles, I've gained valuable experience working with diverse teams and cutting-edge technologies. My focus has evolved to specialize in end-to-end web and mobile application development, where I excel at architecting scalable solutions and delivering comprehensive products from initial concept through to production deployment.

    Beyond Code

    When I'm not coding, I enjoy exploring new technologies, contributing to open-source projects, and sharing knowledge with the developer community. I believe in learning not just for personal growth, but to contribute back to the ecosystem that has taught me so much.
