What I'm looking for

I seek roles combining API integration or front-end development with cross-functional collaboration, clear documentation, and opportunities to grow technical skills.

I am an API Integration Specialist and operations professional transitioning into web development, bringing seven years of customer success and operations experience combined with recent hands-on JavaScript, HTML, and CSS training.

At Lufthansa Systems Hungária I supported airline API integration initiatives based on IATA NDC standards, worked with XML-based APIs, validated requests and responses, coordinated with external partners and internal IT teams, and assisted in testing and documentation in a multinational hybrid environment.

Previously I held sales operations and support roles where I drafted contracts and price offers, managed communications with domestic and international partners, maintained high accuracy in contract documentation, and achieved consistent customer satisfaction and on-time delivery metrics.

I value structured data, clear technical documentation, and cross-functional collaboration, and I bring attention to detail, problem-solving, and multilingual communication to web development and integration projects.
