Brawl Stars Data Pipeline - ETL - Image 1

Brawl Stars Data Pipeline - ETL

Completed

End to end data pipeline built in Python. It extracts live data from the Brawl Stars public API, transforms it into an analytics-ready Parquet dataset, and loads it directly into Azure Blob Storage. I engineered the complete pipeline, architecting the transformation logic with Pandas, containerizing the system with Docker, and building a FastAPI API to orchestrate the entire ETL process.

StudyU Flow API REST - Image 1

StudyU Flow API REST

In Development

AI-powered academic mentor that helps students track their university performance based on their academic records, using a conversational assistant. I co-developed the secure REST API with Spring Boot and JWT, managed data persistence in PostgreSQL, and integrated the AI features using Spring AI. We then containerized the application with Docker for a deployment-ready workflow.

J Sonic (Desktop Multiplayer Game)

Completed

Multiplayer 2D platformer built from scratch. As a core developer, I applied Object-Oriented Programming in Java to architect the game's core systems and co-developed the client-server logic for real-time network synchronization using KryoNet, deploying the server on Microsoft Azure to enable live online gameplay sessions.

Concurrent Gas Station Simulator - Image 1 Concurrent Gas Station Simulator - Image 2

Concurrent Gas Station Simulator

Completed

Multithreaded application that simulates a gas station's complex operations in a concurrent environment. My role was to architect and implement the entire concurrency model in C, using the pthreads library to manage simultaneous threads. I ensured data integrity and prevented race conditions by protecting all shared resources, such as queues and statistics, with mutexes.

Desktop Supermarket Simulation

Completed

Simulates a supermarket checkout system handling complex business rules. As a co-developer, I implemented the core logic in C++ using Stacks and Queues to manage customer and cart data. This backend system interfaced with a WinForms GUI and persisted all transaction data by generating invoice files.

NexusCrawler (Desktop Web Analyzer)

Completed

Web crawler that analyzes site architecture and generates interactive reports. As a co-developer, I engineered its core C++ logic using libcurl for HTTP requests and Gumbo for HTML parsing, and developed the asynchronous tasks to keep the WinForms GUI responsive.
