About
Hey there! I'm Krishanthan, a passionate Software Developer who builds practical solutions through web, mobile, and desktop applications. I started my freelance journey developing projects for different clients across various domains, with my first client project being the Skyline Access Solutions website.
I work with a wide range of technologies including Next.js, Express, MongoDB, Tailwind CSS, Zustand, Prisma, MySQL, PostgreSQL, Java, Hibernate, Jakarta EE, React Native (Expo), and occasionally PHP. I've also explored Flutter and Spring Boot, learning and adapting as needed to complete real-world projects.
Before focusing fully on development, I was a self-taught cybersecurity enthusiast, learning web application security and bug hunting through platforms like HackTheBox and TryHackMe. Although I've paused cybersecurity activities to prioritize university work, it remains one of my long-term interests.
