CardAlpha is a financial technology company based in London, England. CardAlpha’s ePOS App converts a small business owner’s tablet or smartphone device into a powerful electronic cash register.

• Gained insights into the working culture in London. As a full stack developer, I learned to be outcome-focused. Working in a small team, I had the opportunity to work closely with the CEO and CTO to define our product.

• Developed microservices in Golang that communicate over gRPC. Dockerized and deployed on a Google Kubernetes Engine cluster.

• Integrated our API with our partner bank’s API, automating the merchant underwriting and onboarding process. This significantly reduced the time between signing a contract and processing transactions to just a few hours.

• Translated an existing iOS app into a web-based React app. Developed CardAlpha’s web-based mobile app in TypeScript using Ionic, React, and Capacitor. Used native SDKs by developing Capacitor plugins where web views were insufficient.

• Developed CardAlpha’s Pricing Calculator web app using TypeScript and deployed to Firebase.

Galaksiya is a software development and consultancy company based in Izmir, Turkey. The company places high emphasis on internal education to sustain research efforts.

• Learned the basics of software development at Galaksiya. As an intern, I tested the latest technologies and presented the results to the software development team. Having the opportunity to use a wide range of tools and frameworks early in my career has given me the drive to explore new technologies.

• Developed a product catalog web application. Built microservices using the Micronaut Framework in Java. Created a database using PostgreSQL and connected it to microservices using GraphQL. Used Docker for containerization, Docker Swarm for container orchestration, Junit for unit testing, Selenium for large-scale testing, and HTML, CSS, JavaScript for the client side.

• Developed an activity monitoring software to track users’ activity. Built a REST API using the Micronaut Framework in Java and a REST client in Python. Used Elasticsearch to store JSON data from the client. Visualized the content indexed on Elasticsearch using Kibana and automated the build/deployment pipeline with Bash.

• Built dozens of web scrapers with Scrapy-Splash to extract gigabytes of data daily from various e-commerce websites. Prepared extracted data for machine learning model training using Python.

• Performed exploratory data analysis on domain-specific data using Seaborn, Pandas, Matplotlib, and visualized the main characteristics of the data sets.

Established in 1955, Ege University consistently ranks among the top research universities in Turkey.

During my degree at Ege University, I acquired key skills such as teamwork and project management. In my first year of college, I spent much of my free time as a committee member of the Ege Entrepreneurship Society, organizing technical visits to companies and campus events for students. Starting from my second year of college, I worked as a developer, successfully balancing both school and work.
