looksounique is a web app that lets users design and print custom AI-generated t-shirts. Despite using advanced technology, it faced issues with payment processing, leading to its deactivation. A demo version is still available at looksounique.com for demonstration purposes.

• I started a side project to create a web app that makes designing and printing unique AI-generated t-shirts easy. Using Vue, Vite, and Nuxt 3, I deployed it on Cloudflare Pages with Server-Side Rendering for better performance and SEO.

• The app integrated the Stable Diffusion API for creating designs, used Stripe for payments, and Cloudflare R2 for storing images. Despite its advanced tech and innovative idea, the project hit snags in the validation phase, resulting in the deactivation of its payment functions.

• This project is no longer active or maintained; however, a demo version of the web app is still available for demonstration purposes at looksounique.com

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.
