About
Radio Guess
A geography game built on live radio streams and Street View panoramas.

Why this exists
Radio Guess started as a side project: a way to spend time with the thousands of stations that broadcast openly on the internet. Each round pulls real streams from the Radio Browser catalogue, drops you into a Street View panorama, and asks a single question — which of these stations actually comes from this country?
Everything you hear is live. Nothing is recorded or curated in advance, so the answer changes every time you play.

Background
Ten years building web applications, distributed systems and cloud infrastructure. Master's in Computer Science from UFPA, with work spanning carbon-credit platforms at Amachains, Hyperledger networks for Brazil's national research network, and a long run of full-stack product work in TypeScript, React, Node.js, Python and Go.
DCODER is the studio behind that work — custom software taken from idea to production, delivered remotely and directly by the people who build it.
