What I'm looking for

I seek a collaborative environment that fosters innovation and growth.

I am a dedicated Senior Software Engineer with extensive experience in full-stack development, currently working at Mondu in Berlin. My role involves implementing user interface flows for internal administration dashboards and payment widgets using React.js, as well as developing services for the company's risk engine with GoLang and Postgres. I have a strong track record of integrating third-party APIs to enhance risk management and fraud control, showcasing my ability to deliver impactful solutions in high-stakes environments.

Previously, I served as a Full Stack Developer at Bewatec Connected Care, where I designed a high-quality access management tool and implemented micro-front ends using React.js. My experience also includes building an open-source education platform at Hasso Plattner Institute and enhancing customer experiences at FTITouristik GmbH through innovative web solutions. I am passionate about leading knowledge-sharing sessions to foster team growth and reduce technical debt.
