I build secure, test-driven Solana programs and the SDKs, applications and operational documentation required to use them safely.
I bring more than seven years of experience across Web3 and DeFi, with a current engineering focus on Rust, Anchor, SPL tokens, PDA-based custody, CPI authorization, protocol governance, adversarial testing and DeFi architecture.
Currently interviewing for:
- Solana Program Engineer
- Rust Blockchain Engineer
- DeFi Protocol Engineer
- Blockchain Solutions Architect
- Protocol Integration Engineer
Location: United States Availability: Interviewing immediately for remote and U.S.-based opportunities
Portfolio · Flagship Solana Vault · Email
A security-tested Solana vault program built with Rust and Anchor, supported by a TypeScript SDK and a minimal Next.js dApp.

- Safe token transfers through CPI
- Deposit and withdrawal accounting
- Governance and emergency controls
- Two-step authority rotation
- Mint exposure limits
- Exit-first pause behavior
- Account migration and versioning
- Adversarial and negative-path testing
- Devnet deployment and verification
- Test-driven development and gated CI

- 122 dApp tests
- Automated formatting, build, Clippy, test and audit checks
- Reproducible Codespaces development environment
- Architecture decision records, security checklist, runbook and interview walkthrough
The project is intentionally documented as an educational, pre-audit prototype rather than an audited or mainnet-ready custody product.
A DeFi intelligence platform combining market data, technical analysis, machine-learning signals, Solana integration and Telegram delivery.
Research and engineering work focused on DeFi strategies, market structure, risk and blockchain-based financial systems.
Blockchain: Solana, SVM, Anchor, SPL tokens, PDAs, CPI, wallet integration and DeFi architecture
Engineering: Rust, TypeScript, JavaScript, Python, React, Next.js, Node.js, PostgreSQL, Docker and CI/CD
