Enhanced the casino’s customer management system using Angular, NestJS, and SQL Server by centralizing the platform across all casino branches. Unified the customer registration process for multi-site usage and updated the membership card affiliation module, improving both user experience and operational efficiency.

Improved the planning form interface for casino menus with Angular, NestJS, and SQL Server, automating the planning workflow through the use of templates. This made the application more intuitive and faster, improving organization and significantly reducing the time required to create planning schedules.

Developed an access control application with Angular and NestJS to keep employee records and job positions updated, automatically removing inactive staff and preventing errors in workforce management.

Resolved issues in the petty cash system, enhancing the budget generation logic according to the Accounting and Finance department’s rules. Additionally, in the supplier portal, optimized the warnings and alerts system to provide clearer and more timely information to users, using C# and ASP.NET Core.

I developed an MVP in Python (Tkinter) to optimize content uploading on the VTEX e-commerce platform, achieving greater efficiency and reduced processing time through reusable templates.

Subsequently, I evolved the solution into a scalable web production environment using JavaScript (React), Python (Django REST Framework), Celery, LangChain, Redis, PostgreSQL, OpenAI API, Docker, and Nginx. I designed an API and an interactive interface that significantly improved the workflow of the Content and SKU team.

I uploaded and optimized product content using VTEX, MS Excel, and Illustrator. Additionally, I used Selenium and BeautifulSoup to automate data extraction and processing tasks, optimizing repetitive workflows and reducing operational time.
