Experience
Human Dilemmas
The Human Dilemmas project aims to provide an unbiased and open-minded platform for people to share their thoughts and feelings on taboo topics, such as mental health, sexuality, and personal beliefs. It focuses on conducting surveys and research on topics that are often considered difficult to discuss in society and helps educate and raise awareness about these sensitive issues.
As the technical project manager, I managed the technical aspects of the project, including the development and implementation of the survey platform, data collection and analysis, and reporting. I also ensured that the technology behind this platform was secure, accurate, and user-friendly.
The survey platform was designed to be user-friendly and anonymous to encourage participants to be honest and candid in their responses. It was built using the latest technologies and frameworks, such as React, Python, Django, and Postgres.

Racquet Pass Application
https://www.loom.com/share/86eacf1bb7ce4008a82883e8b66c4abfRacquet Pass is a web application that I built using React and Tailwind CSS that connects players and vendors in the sports industry. The platform has user types: Players, and Vendors, with a variety of features to enhance their experience.
Players can search for vendors based on location, rating, and other criteria. The application also allows players to communicate with vendors directly and book services such as training sessions, rentals, and events. They can review the vendors' ratings, read other players' reviews, and leave feedback to help improve the quality of the services.
Vendors can create their profiles, add services, and manage their availability. They can customize their profiles with images to showcase their services. Vendors can respond to players' requests and accept or decline them as per their availability.
I designed the user interface with simplicity and functionality, making it easy for users to navigate and find what they are looking for. The application uses React and Tailwind CSS, providing a seamless user experience with fast loading times, responsive design, and easy-to-use features.
