Viodify
This AI-driven video generation platform, built using React for the frontend and Python (Flask) for the backend, transforms text prompts into engaging videos. It integrates Gemini for text generation, ElevenLabs for text-to-speech, and Google API for sourcing images and videos, while MoviePy handles video editing and composition.

Exceptional Widcc
This enhanced version of the widcc compiler introduces structured exception handling (try, throw, catch, finally) into C. By modifying widcc’s parser and code generation phases, it enables more robust and maintainable error-handling in legacy C code, bridging the gap between traditional C and modern error-management paradigms.

Desktop Apps
Cloudie
Cloudie uses LoRa sensors (Dragino LHT65, Arduino MKR WAN 1310 with MKR ENV Shield) to measure temperature, pressure, humidity, and light. The data is transmitted via LoRaWAN to The Things Network (TTN), processed through an MQTT broker, and securely stored in an SQL database on Microsoft Azure. This system ensures reliable, real-time weather monitoring.

Embedded Systems
RC Car
This modified RC car, powered by an Arduino Uno, integrates IR sensors for line detection and obstacle avoidance, along with an accelerometer for incline detection. The sensors enable autonomous navigation by following predefined paths and avoiding obstacles in real time. A rechargeable battery ensures stable power, making it cost-effective.

Desktop Apps
Weather App
This C# .NET application uses the MVVM pattern to provide real-time weather updates by fetching data from a weather API. Users can search for any location to view current conditions, hourly forecasts, and daily temperature trends. The temperature can be converted between °C and °F.

Embedded Systems
Vault
This Arduino-based vault system features a servo motor lock, a rotary encoder for passcode input, and 7-segment displays for real-time feedback. An OLED screen provides additional status updates. The passcode is stored in Arduino’s memory, ensuring persistence after power loss. After three failed attempts, the system triggers a timeout with a buzzer and LED alert, enhancing security.

Web Development
Games
This web-based project features a game menu where users can choose between Snake and Tic-Tac-Toe. The Snake game challenges players to grow their snake while avoiding collisions. Tic-Tac-Toe offers both a 2-player mode and a 1-player mode with an AI opponent. Built with a focus on interactivity and user experience, this project delivers fun and engaging gameplay.

Resume
Education
University of Twente
Pre-Master Computer Science
2024 - 2025Taken as a minor during my third year at Saxion, I completed a Pre-Master program at the University of Twente (UT) to transition into a WO Master's degree. This program focused on strengthening my mathematical and analytical foundation for advanced academic studies.
Saxion University of Applied Sciences
Bachelor Applied Computer Science
2022 - 2026At Saxion I gained expertise in both software engineering and embedded systems. The program combined theoretical foundations with hands-on experience, covering topics such as programming, system architecture, hardware-software integration, and real-time computing. Through practical projects, I developed skills in designing scalable software solutions and working with embedded systems for automation and IoT applications.
Courses
IBM
Full-Stack Developer
2023 - 2023Through this program, I developed a strong foundation in full-stack web development, working with HTML, CSS, JavaScript, React, and Bootstrap for front-end design. On the back-end, I gained experience programming with Node.js, Express, Python, and Django, building server-side logic and handling databases. The course also introduced cloud-native development, where I learned how to deploy and scale applications using Containers, Kubernetes, Microservices, and Serverless Functions.
Cybersecurity
2023 - 2023In this course, I learned the fundamentals of cybersecurity and how to protect networks, systems, and data from potential threats. I explored common risks, vulnerabilities, and attack techniques, along with strategies to mitigate them. Using Security Information and Event Management (SIEM) tools, I gained practical experience in monitoring security events and detecting potential breaches. The course also covered essential Python, Linux, and SQL skills, helping me develop hands-on expertise in securing digital environments.
