What I'm looking for

I seek a collaborative environment that values innovation and offers growth opportunities.

I'm a Senior Software Engineer with over 15 years of experience, primarily focused on Ruby on Rails development. My journey has taken me through various roles where I've not only honed my technical skills but also embraced leadership opportunities. I have a strong background in DevOps and mobile development with React Native, which allows me to contribute effectively to diverse projects.

Throughout my career, I've led teams on international projects, mentored junior engineers, and collaborated closely with product owners, project managers, and designers. My work has involved improving existing integrations, enhancing project workflows, and implementing innovative solutions to drive project success. I thrive in remote environments and am passionate about leveraging technology to create impactful digital experiences.
