Professional Experience

Independent Software Engineer / Founder · Zanvexis

Jan 2024 - Present

São Paulo, Brazil (Remote/Global)

  • Architected and deployed an asynchronous Solana HFT Copy Trading Bot in Rust using the Tokio framework, handling multi-account events with dedicated telemetry logged in SQLite.
  • Developed an atomic Arbitrage Flash Loan Bot targeting Solana DEXs (Raydium, Orca) and lending protocols (MarginFi), optimizing transaction grouping to guarantee atomic on-chain execution and mitigate slippage risks.
  • Engineered a high-frequency hybrid trading engine (Apex HFT V8.5) using Rust and Python for perpetual markets on BingX, optimizing order placement and risk mitigation modules for sideways market conditions.
  • Built a production-ready Enterprise Multitenant Boilerplate in Go using Chi and SQLC for clean PostgreSQL communication, implementing strict RBAC (Role-Based Access Control) and high-speed data auditing.
  • Consulted for global clients on Web3 infrastructure, focusing on performance bottleneck elimination and code security auditing.

Core Projects & Hackathons

Core Developer · STRATA Protocol

DeFi & Structured Credit

Designed and implemented an on-chain tranche vault (Senior/Junior structure) on Solana inspired by traditional asset-backed security funds (FIDCs). Built the smart contracts using the Anchor framework, incorporating automated yield distribution mechanisms and strict capital risk containment rules.

Technologies: Solana · Rust · Anchor · TypeScript

Core Developer · Sovereign Web3 Identity Layer

Decentralized Identity (SSI)

Developed a decentralized identity (SSI) framework using DIDs and Verifiable Credentials to enable secure, privacy-preserving compliance checks on-chain. Integrated basic zero-knowledge proof concepts to verify user attributes without exposing underlying sensitive private data.

Technologies: W3C DIDs · Verifiable Credentials · Rust · ZKP

Core Developer · SmartFlow Analytics Engine

On-Chain Telemetry

Built a real-time smart money tracker for the Solana ecosystem, ingesting and parsing complex transactional data streams via Helius RPC and Birdeye APIs. Optimized data filtering algorithms in Python to extract wallet movement signals with minimal processing delay.
