I am working on creating visualizations for road features, including speed limits, traffic signs, and lane events, to ensure regulatory compliance for vehicle certifications in both the US and Europe. I also work on a KPI testing tool to enable accurate labeling of key roadway elements such as lanes, signs, and traffic lights, improving the car’s recognition software precision
• Technical Details:
  • For my intern project, I mostly used C++ to write the algorithms and perform different road elements calculations to visualize the road features, including speed limits, traffic signs, and lane events. I created the visualizations using a C++ library ImGui
  • I also have to write JavaScript scripts and process JSON car data output files
  • For testing, I wrote a lot of unit tests and Parametrics Tests (P-Test) using GoogleTest for my speed limits and traffic signs calculations

Treevia an online multiplayer trivia game - SLB

• When: Jan 2023 - May 2023

• Where: You guys can check out this post I write about this huge class project with SLB deployed website. You can also see a video demo of our product here

• Technical Details:

  • Browser Application: to build the frontend of the website, we used Next.js, Vercel, TypeScript and Tailwind CSS
  • Cloud Application: I used Azure Services to host the application and performed all the functionalities including authentication, profile management, lobby creation & join and gameplay. We also used SignalR for group communication and team playing in the game.
  • Backend: The project implements microservices architecture I mainly used C#, ASP.NET, serverless Azure Functions in the backend. Each function is deployed and run independently and concurrently, allowing the system to be resilient to failures
  • Database, we used MongoDB in Azure CosmosDB for efficient document reading and Azure Blob Storage for storing files and images. I also worked on the database system including the CosmosDB MongoDB API.
  • Deployment: Using Azure CLI, Python, and Java, I created a deployment script that simplifies the process and automates the setup of essential services
  • Testing: In our testing process, we have implemented a streamlined workflow that combines Postman collection export and Azure DevOps integration. This approach enables us to efficiently test our APIs, ensuring their functionality remains intact during code changes and pull request merging. I also wrote a lot of unit testing for the Azure Functions
