My responsibilities were identifying the most qualified applicants via interviewing and providing feedback to the applicant and the hiring team.

As a team member, my role was to provide all-around software engineering services to Travelport for the Travel Cloud Pro system, which is designed to automate air segment booking, exchange, refund, and more for travel agencies and agents. Every licensed travel agency in the EU now uses the solution.
It's impossible to list everything I've done in this role, but highlighted contributions are:

- Developing and implementing new complex features, while also modifying, refactoring, and completely rewriting existing ones to meet the evolving needs of the project.
- Quickly identifying and resolving a significant number of bugs, while also participating in implementing an automated error monitoring and reporting system.
- Redesigning the architecture of key services and revamping the web interface of the entire application to improve usability, look, and performance.
- Leveraging a wide range of AWS services such as S3, DDB, CloudWatch, and Lambda to ensure scalability and reliability in a serverless system.
- Participating in the entire development lifecycle, from small components with React to large-scale ticket exchange services, and providing DevOps support to ensure smooth deployment and maintenance.
- Conducting thorough testing, including unit tests, integration tests, and visual tests. I also played a key role in building an internal application-specific testing library to simplify writing new tests.
- Achieving significant performance improvements by moving to functional components, using hooks and getting rid of unnecessary updates, and ineffective usage of localstorage/indexeddb/websql, with a continuous focus on optimization.
- Implementing security patches related to tokens to keep the system secure.
- Making open-source contributions to the Travelport projects, one of which is uapi-json.
