Experienced Ruby Developer specializing in Ruby on Rails, system architecture, and integration of diverse technologies.

With nearly three years of experience as a Ruby Developer and Team Lead, I specialize in healthcare software development, team management, and system optimization. My skills in Ruby on Rails, AWS, Docker, and integrating technologies such as Twilio and Sendgrid are well-honed. My career highlights include developing critical healthcare applications, mentoring a trainee to junior level, and leading a significant IoT healthcare project. I am adept at optimizing systems, API integration, and leading diverse technical teams. My linguistic abilities include proficiency in English and basic German, complementing my technical expertise in delivering efficient, scalable software solutions.
