Projekthistorie
I worked as both a software engineer and a data engineer at Delivery Hero
Worked closely with Data Scientists to design and create a data orchestration pipeline from scratch that handles hundreds of terabytes of data daily. It also performs data cleaning as well as quality checks. I added an API endpoint to allow other entities in the company to fetch data relevant to their needs
• Developed a Loyalty Point System and an API to interact with it. The service and its API are being used by other software engineers, in the company to create cashback campaigns. This improved the retention rate of many of our customers by 30 % and made them more loyal to our platform.
• Revamped the current billing system for restaurants that use our platform. This helped the company to be more transparent with what it bills the restaurants and in turn, helped the restaurants to better understand their invoices.
• Created a new Payment Service used to execute different types of online payments including credit cards and PayPal.
• On-boarded junior software engineers and coached them on the tools and services we use and guided them through the codebase.
Tools/Tech used: Python, Poetry Django, Celery, Docker, PostgreSQL, Terraform, CI/CD, Kubernetes, GCP, Cloud Composer, Big Query, Airflow, New Relic, Kibana, Sentry, Git

Peach Aviation - Osaka, Japan (3rd largest Airline in Japan)
* Designed and implemented a RESTful API used by third parties to retrieve the company's flight data for any period.
* Implemented a near real-time flight status system by creating a RESTful API that fetches data either from the database
or from a cache. This system updates itself every 5 minutes and displays future flight data, which are flights that are
scheduled 6 days in advance. It is mainly used by the pilots and cabin attendants to schedule their shifts for the week
and by business analysts to get real time data when needed.
* Installation and maintenance of airport counters and self-check-in kiosks at new flight destinations.
* Designed and develop a GDPR compliant pilot/cabin attendant recruitment platform. The platform records the relevant
data potential candidates and provides the data in a user-friendly usable for recruiters. It enables them, among other
things, to easily search for candidates, rate them on various criteria such as soft and hard skills and aggregate the whole
data to on certain criteria which can help them to decide on which candidate to hire.
