Full Stack Developer & Ai Engineer | Web3, Security & Systems

AI engineer and full-stack developer focused on Web3, security, cryptography, and systems tooling. I turn ambiguous product and research requirements into tested, documented software across Python, TypeScript, Rust, C++, and Solidity.


I use AI coding agents as engineering tools while personally owning architecture, technical decisions, code review, correctness, security, testing, documentation, and final delivery.


Selected work:

  • EllipticZero Research Lab — multi-agent smart-contract review and defensive ECC research workflow with a 325-test release gate.
  • Memory Genome Engine — local-first Rust memory engine with CLI/TUI, JSON-RPC, Python/TypeScript SDKs, encrypted stores, and reproducible benchmarks.
  • ProofStampBot OSS — TON notarization product with payment validation, anti-replay controls, PDF/QR certificates, Docker, and CI.
  • SBX-XorFilter / SBX-BinaryFuse — deterministic C++11 probabilistic filters with compact memory layout and thread-safe lookups.


Available immediately for a stable long-term remote role, contract, part-time retainer, or paid trial. Stack-flexible and able to learn company-specific systems quickly.


I am available for an entirely asynchronous written hiring process: technical questions, GitHub/code review, a take-home assessment, or a paid trial.

Experience

Independent Crypto/Web3 Research & Product Development
ECD5A
2018 - 2026
Since 2018, I have independently studied and worked with cryptocurrency markets, Bitcoin and Ethereum protocol internals, applied cryptography, security, DeFi, and CeFi. Since 2026, my main engineering focus has been designing and delivering AI-assisted Web3, security, and systems products while personally owning architecture, technical decisions, code review, correctness, testing, security, documentation, and final delivery. Built cross-language products across Python, TypeScript, Rust, and C++, including EllipticZero Research Lab, Memory Genome Engine, ProofStampBot OSS, README Arcade, and high-performance static membership filters. I use coding agents as engineering tools, not as a substitute for verification or responsibility.
