Artur Pietrzak
IT engineer and developer
Web developer with over a year of experience in software engineering, graduate of Łódź University of Technology with the title of IT Engineer. My core stack consits of React.js, Next.js, TypeScript, SCSS, MySQL and Prisma. Additionally, during my studies and while creating personal projects I learned other technologies, such as C#, .NET, Java, Spring and React Native.
As of recentely, I have also been gaining knowledge in the field of artificial intelligence and machine learning, focusing on the domain of natural language processing. I gained experience in Python, PyTorch and Pandas by developing a customer service chatbot based on a Large Language Model called Llama 2.
Experience
- Assisted in building a chatbot based on Mistral LLM, which constituted the first line of support for users communicating with the customer service department.
- Created and processed datasets by using uncategorized data collected by the company.
- Introduced Sentry as a performance measuring and error-tracking tool for the project, which helped with detecting and fixing errors, making the website more reliable.
- Prototyped a functionality of automatically creating, filling with data, and sending documents to doctors using DocuSign API, which greatly simplified the process of obtaining documentation for the user.
- Developed a ReactJS hook for saving, retrieving, and validating data stored in local storage, improving user experience by persisting form information, even after the website was closed.
- Refactored the project to implement accessible and semantic HTML and CSS to comply with WCAG 2.1.
- Assisted the engineering team in maintaining and developing a web catalog project.
- Ensured code clarity, consistency, and correctness by regularly performing code review of pull requests created by other team members.
