What I'm looking for

I seek a dynamic environment that values innovation and collaboration, offering opportunities for growth and impactful projects.

I am a Senior Software Developer with extensive experience in building innovative applications across various platforms. My journey began in the medical technology sector, where I designed software for ultrasound devices, and has evolved into developing cutting-edge solutions in blockchain and AI. I thrive on challenges and have a proven track record of enhancing user experiences through technology.

Most recently, I worked as an Independent Consultant, where I engineered a native iOS application for the Pangea Foundation, showcasing my ability to integrate blockchain technology with user-friendly interfaces. My role at Privado.id involved implementing an iOS SDK that leverages zero-knowledge proofs for identity verification, demonstrating my commitment to secure and efficient software solutions. I have also led teams in developing applications that significantly improved operational efficiency, such as increasing kiosk transaction success rates from 60% to 99.9%.

With a strong foundation in both software development and project management, I am passionate about mentoring others and fostering a collaborative work environment. I am always eager to learn new technologies and methodologies to stay at the forefront of the industry.
