Alexandru Cambose

I'm a software engineer with a knack for tackling complex problems and a passion for finance, web3 and blockchain. With over 7 years of hands-on experience, I've had the privilege of wearing diverse hats ranging from frontend and backend developer, to mentor, architect, and team lead.

I take pride in constantly stepping out of my comfort zone and embracing new challenges. I firmly believe that success is a collective effort. Driven by curiosity, I'm always eager to learn, adapt, and stay on top of the latest developments in tech and finance.

When I'm not at the computer, you'll probably find me exploring new places and seeking out adventures.
