Backend developer, 22 y/o, based in Blumenau, SC. Started coding at 17 and never really stopped — 3+ years of professional experience, currently at a fintech building high-volume transaction systems. Degree in Information Security, which shapes everything: auth-first thinking, least privilege by default, security baked into the architecture from day one — not added at the end. Backend is where I live: APIs, event-driven systems, DDD, cloud on AWS.
