As a key member of the Metis team in the Flight Department at KLM, one of the world's largest airlines, I leveraged wide-ranging technologies including Python (FastAPI, Django, SQL) in building, maintaining, and modernizing the flight landscape applications:

• Led a complete overhaul of the crew roster and planning application using Python (FastAPI, Django)
• Engineered and sustained a hybrid application using the Ionic Framework and Angular, adeptly managing over 5,000 daily users.
• Introduced Node (NestJS) for backend projects
• Utilized PostgressSQL for efficient data management and manipulation across projects.
• Established an automated CI/CD pipeline leveraging Atlassian Bamboo
• Implemented automation systems and continuous integration and deployment build server
• Effectively utilized React for front-end development and Azure for cloud computing solutions across various projects.
• Conducted thorough code reviews to identify potential areas for improvement, ultimately enhancing code quality across all projects handled by the team.
• Designed robust testing frameworks to validate functionality and ensure a high level of quality assurance.

I was contracted as a Software Engineer for a React Native health-tracking application. My primary responsibility was to collaborate with a team of developers and train data science models with an on-site General Practitioner application. These models were then integrated into the React Native application to automate certain parts of the client triage process.

Key Achievements:

• Led the development of a React Native health-tracking application that revolutionized client triage in the medical IT sector.
• Utilized my expertise in React Native, React, Ionic, and Angular to create a seamless user interface and ensure a smooth user experience.
• Developed comprehensive testing protocols using Jest, Enzyme, and Cypress to ensure application stability and maintain high-quality code standards.
• Optimized application performance to deliver a faster and more responsive user experience.
• Automated the release process, reducing software deployment time and accelerating feature delivery.
• Leveraged a NoSQL database like MongoDB to efficiently store and manage data in the application.

It was one of the most wonderful experiences. Snapp is the leading ride-hailing service.
 It has recently reached over 2.5 million successful rides per day, which is a worldwide record only after 4 years of activity in a single country.

What I have done here:

• Re-engineered web application with React, Redux, Typescript which resulted in a 45% reduction in the final JS bundle, 92% reduction in CSS file and major increase in performance (based on performance reports).
• Worked on the Snapp's React UI-kit Library with more than 90% test coverage. built from scratch, it has been published as a private npm package with storybook and ... This project is also used across all projects at Snapp and helps us to simplify UI implementation in all projects in Snapp .
• Training and mentoring new developers. reviewing their works, helping them on their tasks and answering their questions. it helps us to find amazing people after this program.
• Develop and maintain 5 contentful websites with Gatsby and NextJs considering the SEO improvements that resulted in 90% improvements at lighthouse reports.
• Creating CI/CD, handling deploys and production releases, creating git flow, write test for every single page and ... that cause managing and structuring better teams in Frontend.
• Managing 4 frontend developers (as Tech Lead) on a cross-functional (including Designers, Developers, QA, product managers and …). reviewing merge requests, training new joiners and hiring new fantastic people to the team.
