Projects I'm proud of, built with care and clarity.
PiCar-X v2.0 – IoT Smart Robot Car
An IoT smart robot car project built with a Raspberry Pi 4 and the SunFounder PiCar-X kit. It reads sensor data in real time (distance, line tracking, etc.) and publishes telemetry to the cloud using MQTT (Adafruit IO). The goal is to combine embedded systems + networking to create a responsive robot platform with remote monitoring, automation, and data logging.
Tech: Python, Raspberry Pi 4, SunFounder PiCar-X, MQTT, Adafruit IO, Linux
MANA – Mobile App for Non-Profit Event Management
A full-stack mobile application built for MANA, a non-profit organization, to manage community events and participant registrations. The system uses a React Native frontend and a Spring Boot microservices backend, following clean architecture and domain-driven design principles. Features include secure authentication, event discovery, real-time registration status, capacity management, notifications, multilingual support, and admin event management. The project emphasizes scalability, accessibility, and reliability, and was developed using Agile Scrum with CI/CD pipelines, automated testing, and cloud-ready deployment.
Tech: React Native, Spring Boot, Java, PostgreSQL, Docker, CI/CD, GitHub Actions, Domain-Driven Design
