In my current role as a full-stack developer at PowerPay, I specialize in building efficient applications using React and Rails. My dedication to continuous learning keeps me at the forefront of technological advancements, enabling me to deliver innovative solutions.

Beyond my professional endeavors, I find joy in life's simple pleasures. I cherish spending quality time with my friends, girlfriend, and my loyal 13-year-old dog. An avid reader, I enjoy exploring diverse genres that broaden my perspective. I also prioritize staying active through regular workouts and find peace in nature's tranquility.
