What I'm looking for

I’m looking for hands-on security roles where I can build tooling, perform advanced pentests, grow defensive skills, and contribute to a collaborative, learning-focused team.

I’m an ethical hacker and software engineer focused on offensive security, penetration testing, exploit development, and building security tools. I’ve achieved top competitive rankings, including #1 in Sri Lanka on HackTheBox and global #25 in 2022, and earned “God Level” on TryHackMe.

I build practical security tooling and proof-of-concept exploits across Linux, Windows, Android, and iOS, including an advanced Bluetooth penetration testing tool and privilege escalation automation scripts. I also create software projects such as mobile apps, desktop systems, mining software, and ML-based crypto predictors.

I hold a BSc (Hons) in Computing (reading) and multiple certifications and diplomas spanning ethical hacking, digital forensics, network defense, blockchain, and software engineering. I’m actively expanding defensive security skills while continuing offensive research and tool development.

I bring a results-driven, hands-on approach backed by competition success, real-world labs, and practical project delivery; I’m passionate about securing systems and mentoring best practices through pragmatic tooling and continuous learning.
