About Me
Software developer with around 2 years of experience, both professionally and freelance, building web projects for different clients and partnering with marketing agencies on their clients' digital solutions. My experience spans from designing and scoping a solution to implementing and shipping it to production, including websites, applications, and management systems (ERP, CMS, CRM) with integrations to third-party APIs and services. Working across companies and organizations in different industries has taught me to adapt to varied needs, analyze problems in depth, and propose tailored solutions rather than just executing tasks.
