Arun K Biju, Full Stack Developer

About Me.

I’m a passionate Full Stack Developer with a love for turning ideas into impactful digital experiences. My journey began back in 2017 out of pure curiosity, and over the years, it evolved into a deep commitment to mastering both front-end and back-end technologies. With hands-on experience in tools and frameworks like React, Node.js, MongoDB, MySQL, Python, and Firebase, I enjoy building secure, scalable, and user-centric web applications. With nearly 2000 GitHub contributions, I’m committed to continuous learning and pushing the boundaries of what I can build.

One of my notable projects includes developing and deploying a college fest website where participants could register for events directly. Using the Google Sheets API, I collected data such as timestamps, names, emails, academic details, payment IDs, and payment proof URLs (converted to Google Drive links). Although I initially implemented this using Firebase and Supabase, I adapted the solution to Google Sheets to meet the event coordinators' workflow — showcasing my ability to build reliable systems and quickly adapt to user needs. The project was hosted on GitHub Pages and handled all front-end and back-end logic efficiently.

Outside of full stack development, I also explore Ethical Hacking with practical knowledge of tools like Kali Linux, Metasploit, Burp Suite, Hydra, and Nmap — giving me an edge in system security and behavior. I’m also learning Game Development using Unity and C#, currently working on 2D projects like Flappy Bird to strengthen my creative and logical thinking.

I’m currently in the final phase of my engineering degree and open to exciting job and internship opportunities. Whether I’m building secure web apps, solving real-world problems, or experimenting with new tech, I stay curious, adaptable, and driven to create meaningful digital solutions.
