Full-stack engineer and community manager, building product and community in the Solana ecosystem.
I'm Rafael Souza, known online as Raffx. I'm 22 years old and I work as a full-stack engineer and community manager. My work brings together product building and community development, from React/Next interfaces to services and contracts in Rust. I build well-structured products and spaces where people can connect, participate, and grow.
Today, I work with React, Next.js, and Angular building SaaS products at A5 Solutions. At the same time, I lead the structuring of JET LATAM, a regional initiative connected to the Jito ecosystem on Solana. Throughout my journey, I've also moderated Discord communities and led educational initiatives around AI.
I hold a degree in Information Systems from FIAP, where I built my foundation in programming, business, and project management.
I believe great products and great communities come from the same place: attention to detail and respect for people's time.

A peg-risk oracle for Solana, a privacy-first treasury layer, a regional hub for the Jito ecosystem, and an educational bot — four angles on how I think about products and communities.
Pegana is a peg-risk oracle for Solana, an early-warning system that measures the gap between an asset's intrinsic value and its executable market price, flagging deviations before risk moves downstream. It tracks 22 pegged assets, from liquid staking tokens to stablecoins, and publishes every state change across five surfaces: REST, WebSocket, MCP, webhooks, and Telegram. The whole system runs on a Rust microservice pipeline with a public, reproducible Trust Layer. Alpha on mainnet.
Aegis turns multisig treasury payments into privacy-preserving, auditable transfers without breaking existing approval workflows. Built on Squads and powered by Cloak, it enables Solana-based treasuries to run payroll, invoicing, and audits without exposing sensitive on-chain data, with scoped, time-bound audit access and signed exports. v0 live on Devnet.

What does RPC stand for in blockchain infrastructure?
An educational bot for SuperteamBR that delivers glossary entries, quizzes, and contextual explanations directly inside the chats where the Solana community already lives. It supports DMs, groups, and inline mode, in Portuguese, English, and Spanish. It reduces onboarding friction without taking anyone off-platform.
Recognition that validated the work under competitive pressure.
Selected among 95 submissions as one of the solutions that best demonstrated real-world private payments — private execution on top of Squads, powered by Cloak.
