About

I’m a first-year computer science student at Middlesex University Mauritius, graduating in 2029. I’m learning cyber and network security on my own by building AirCommand, a Wi-Fi auditing tool. My team of three came second at Hack the Campus, a capture-the-flag competition.

In 2026 I worked on three hackathon projects with teams, and all three won prizes: 1st place at Finnovate, 2nd prize at Game of Code and the Coup de Cœur prize at Build with Gemma. Each case study says what my part was and what it runs on.

I’m COO and one of five co-founders of Team BlackReef (opens in a new tab), a software studio in Mauritius that builds websites, apps and custom software. We all do a bit of everything; I have the final say on QA, testing, auditing and operations.
