What I'm looking for

I am looking for a collaborative environment that fosters innovation and growth.

I am a dedicated Backend Software Developer with a strong focus on Ruby on Rails and PostgreSQL, currently working at Runrun.it. My experience includes designing and implementing solutions for mass data processing, which has significantly enhanced system performance by reducing execution time by up to 40%. I have a proven track record of upgrading legacy systems to modern frameworks, ensuring long-term maintainability and security improvements based on comprehensive pentesting reports.

Prior to my current role, I worked as a Fullstack Software Developer at Mainô, where I contributed to the refactoring of the subscription module and implemented React components to improve user experience. My earlier experience includes web development at GTConcept, where I maintained inventory management software and developed a web scraper for automating intellectual property checks. I hold a Bachelor's degree in Communication and Business, which complements my technical skills with a strong understanding of user needs and business objectives.
