I find gaps.
Then I build the thing that fills them.
Open data infrastructure for the Brazilian crypto and FX market - built from zero, shipped to production, used by real people.
Story
The gap I found
Brazilian crypto investors had no single, reliable source to answer a basic question: "Does my exchange report to the Receita Federal for me - or am I on my own?" The data existed - scattered across BCB resolutions, CVM circulars, and exchange footers - but no one had structured it. So I did.
What I built - and how fast
I started with the hardest product: DolarMap, a real-time BRL/USD tracker that monitors rates across Brazilian exchanges, runs a live arbitrage engine, and pushes alerts to users on Android. Three months from first commit to Play Store. The system has since sent over 2,000 alerts - including one on March 22, 2026, when USDT was 23% cheaper on one exchange vs. another. Users who acted on that alert with R$ 1,000 walked away with R$ 1,230 in minutes.
Then I turned to regulatory infrastructure. In two days I catalogued 24 exchanges with CNPJ, BCB authorization status, Pix support, tax regime, and RFB obligations - then exposed it as a free JSON API. No rate limits. No authentication. No paywall. The kind of data that regulators, developers, and compliance teams needed and couldn't find.
What's next
Stablecoins Brasil - a structured overview of the stablecoin market in Brazil: volume, backing, issuers, and BCB regulatory framing. The same gap-first approach, applied to the fastest-growing segment of the Brazilian crypto market.
Background
Skills → bitsARK proof
| Skill | How bitsARK proves it |
|---|---|
| Gap identification | Found two structured data voids in the Brazilian market - FX arbitrage visibility and exchange regulatory compliance - before building either product. |
| Execution velocity | DolarMap: 3 months from zero to Play Store. Exchanges API: 2 days from idea to public endpoint. Both live, both used. |
| BR regulatory depth | Mapped IN RFB 1888, Lei 14.754, BCB authorization status, and Pix compliance across 24 exchanges - in structured form, publicly available, for free. |
| BizDev / GTM | Designed organic acquisition around IRPF season as the primary pull channel. Built free tools that create inbound without paid distribution. |
| Product thinking | Designed for zero friction by default: no API keys, no rate limits, no registration. Removed every barrier between the user and the data. |
| Operations background | Prior background in e-commerce operations and business administration - understands unit economics, international market entry, and growth loops. |
Open to opportunities
Let's talk
I'm looking for roles in Business Development, Founder/Operator in Residence, Go-to-Market LATAM, or Crypto/Fintech Angel Scouting - at companies that need someone who knows the Brazilian market from the inside. If you're at Strike, Bitso, Coinbase, Chainalysis, Fireblocks, or any company building in or into Brazil, I'd like to hear from you.
