Beyond Code

I believe the best engineers are built outside the IDE too. Marathon runner, hackathon competitor, and always learning in public.

When I'm not shipping code, you'll find me training for my next race, competing in hackathons, or sharing engineering insights on LinkedIn. I moved to the UAE to build at the intersection of tech and ambition, and I bring that same energy to every product I touch.
