Smart Contract Engineer

Smart Contract Engineer with 10+ years of development experience and 4 years of Blockchain engineering experience.

I build DeFi smart contracts: AMM design (Uniswap V4 hooks, Algebra Integral plugins, DEX aggregation), token launchpads and tokenomics (bonding curves, option tokens, ICO tooling), and Smart Contract Security (audits, stateful fuzzing, invariant testing).

Shipped 8 DeFi protocols to production, plus the tooling around them: Subgraphs, SDKs and MCP servers that let AI agents launch and trade onchain.

Highlights:
- Rewrote the Camelot DEX aggregator, now the default router on every Camelot, Cypher and Sheriff chain, for a DEX with 23B+ USD in 2025 volume across 18+ chains.
- Designed and built Beraborrow's POLLEN tokenomics layer from scratch in 24 days for a CDP that peaked at 423MM USD TVL (4th largest). The POLLEN sale raised 1MM USD at a 42MM USD FDV.
- Hardened Beraborrow's 33 Managed Leveraged Vaults through the 2.7B USD Boyco unlock with a NECT loss-compensation mechanism and 40+ tests.
- Owned the Y2K Earthquake V1 testing and hardening for a protocol that cleared 100MM+ USD in deposits in 6 months and settled 9 live depegs without incident, FTX week and the SVB weekend included.
- Built Cypher's ICO platform, which raised 777 ETH (2.1MM+ USD) from 785 buyers. The CYPH sale sold out its 1.5MM USD cap in under 3 hours with no VCs.
- Designed the CYPH token stack: 107MM CYPH (10.7% of supply) escrowed, 3070 option exercises worth 93 ETH towards the protocol's treasury, and 17.2MM CYPH bought back through 890+ automated distributions.
- Led Poolshark Protocol's Product team from a 270-user closed beta to a 5000+ sign-up beta and an Arbitrum Mainnet launch. The FIN public sale sold out 135 WETH (300K USD) in 43 minutes, alongside a 900K+ USD private round.
