// summary

Protocol engineer for on-chain derivatives. Led protocol engineering on Adrena, a live Solana perpetual-futures DEX ($9.7B lifetime volume): the core Anchor program, a multi-provider oracle publishing ~94k signed price batches per day, liquidation / stop-loss / limit-order keeper engines, security-audit remediation, DAO-governed releases and 24/7 node ops. 3+ years shipping production financial infrastructure in Rust, Anchor, Solidity and TypeScript across Solana, EVM, Casper, Mina and CreditCoin, working daily with pool-to-peer perpetuals mechanics (margin, leverage, funding, liquidation) and TradFi market data: US Treasury rates, the VIX, Nikkei 225 with FX conversion, S&P 500 and single-stock synthetics gated by US / JPX venue calendars.

Adrena · Lead Protocol Engineer
Live Solana perpetual-futures DEX (adrena.trade) · $9.7B lifetime volume, $195M peak day · winding down 2026
  • Became the #1 contributor to the live mainnet Anchor program (131 instructions) within 7 months of joining the ~5-person team: 47% of program commits and ~35% of the surviving 118k-line Rust codebase. During this tenure the protocol processed ~$890M volume across 941 traders and 6,274 positions (~$3.9M avg/day).
  • Designed and shipped the Virtual Funding Rate engine (open-interest-imbalance-driven cumulative funding indices with per-market caps) and the synthetic RWA/commodity pool system: gold, silver, WTI crude, S&P 500 and NVDA perp markets with signed market-hours attestations and advance-only anti-replay, the platform's first US-equity perps, live on mainnet Apr–May 2026.
  • Authored the multi-provider oracle system (~89% of the oracle state module; min-agree consensus across providers incl. Switchboard) and MrOracle, the Rust price-publishing keeper that landed 10.2M signed price batches (~82M price points) in its first 100 days, sustaining ~94k/day over the trailing 8 weeks, using versioned transactions + address-lookup-tables under Solana's tx-size cap with multi-tier RPC fallback.
  • Owned a third-party security-audit remediation end-to-end: triaged 33 findings, patched all applicable critical/high/medium (incl. two-step admin transfer with 48h timelock), executed zero-realloc account migrations across three schema versions, and ran SHA-256-pinned verifiable-build releases through Realms DAO governance.
  • Sole author of the liquidation, stop-loss/take-profit and limit-order execution keepers, the market-hours gate and the buyback service (Rust + TS); #2 contributor to the Yellowstone-gRPC event-driven execution keeper (Jito bundle submission).
  • Operated the fleet 24/7 at ~95%+ availability with weekly maintenance windows; co-maintained the staking keepers behind 312k protocol-lifetime reward claims (~153M ADX + $4.0M USDC).
  • Operated Adrena's dedicated non-voting RPC + Yellowstone gRPC (Geyser) node (Agave; 96-core / 755 GB / 7 TB NVMe): ~80 req/s at 99.9% HTTP success, 7 external gRPC subscribers, TLS + auth-gated behind nginx.
  • Ran the 42-day "Forge" trading-competition infrastructure (428 registrants, 434k hourly scoring snapshots at 99.2% coverage), the public competition data API and the Discord observability bot; shipped 110+ merged PRs on the Next.js trading frontend.

Diamond Pools · Co-founder, Contracts & Backend
Quantified yield protocol on Solana built around ORE mining (diamondpools.app) · 3-person team: product / quant / engineering
  • Sole author of the Anchor vault protocol across two generations (57-instruction v2): share-token NAV accounting, three risk-tier buckets, multi-engine strategy routing and a bounded referral treasury, hardened with 290+ Rust unit tests and 380+ integration cases incl. an executed ERC-4626-style inflation-attack test.
  • Built the entire off-chain layer solo: strategy keepers, crank/settlement services, analytics ETL (Postgres + REST/WS), referral indexer with attestation-based settlement, typed SDK/ABI pipeline and most of the frontend.
  • Ran a 3,120-trial strategy-parameter sweep (zero failures) over ~1 GB of on-chain mining datasets with Calmar/stability ranking and a documented promotion procedure, iterating with the team's quant.

Autonom · Backend Engineer, Oracle & Market-Data (Rust)
Upstream signed price-data provider for Adrena (terminal.autonom.cc) · first collaboration Aug 2025
  • Built Rust (Axum) market-data integrations onboarding TradFi instruments into the production feed: US Treasury-bill rates (FRED), the VIX, Nikkei 225 (JPY to USD) and US- and HK-listed equities (HKD to USD); wrote provider-integration test suites across five data vendors.
  • Extended the operator's market-hours system with a JPX venue calendar and per-feed open/close windows embedded in the signed Adrena-compatible price payloads.
  • 2025: built a dual-chain quantum-entropy RNG oracle (single Rust binary with EVM + Casper lanes; ANU quantum entropy; Merkle commit-fulfill flow) with systemd deployment runbooks.

Doot Foundation · Founder & Sole Engineer
Trust-minimized zero-knowledge price oracle for Mina Protocol + Zeko L2 · zkIgnite Cohort 2 grantee
  • Founded and solely built and operated for ~2 years a ZK price oracle aggregating 10 assets from 20+ data providers on a 10-minute cadence (Mina devnet + Zeko L2): o1js smart contracts with recursive ZkPrograms and off-chain-state rollups, every provider response Schnorr-signed before aggregation and historical aggregates pinned to IPFS.
  • Reimplemented Mina's Pallas-curve Schnorr signature verification from scratch in Solidity (~2.9k LOC) and deployed it to Arbitrum One mainnet (mirrored to Ethereum via LayerZero) so EVM contracts can verify Mina-signed oracle data on-chain.
  • Published the full integration surface: @dootfoundation/client npm SDK (12 releases, automatic API to L2 to L1 fallback), REST API, developer dashboard and docs; also primary author of Fizk Protocol's (formerly zkUSD) oracle-price-provider: the stablecoin's multi-provider signed price service, with certificate-pinned DNS-over-HTTPS provider fetching, resolver fallback and TTL caching (Dockerized, 2025).

Elemental Blockchain · Smart-Contract & Full-Stack Engineer
Contract engagement
  • Authored the core Trading + Positions (ERC-721) contracts for POP! Protocol, an EVM perpetual-positions DEX with an off-chain sequencer-signed order flow, and built its trading interface.
  • Lead contributor to EBSS, an on-chain B2B invoicing/escrow platform on Polygon: built the frontend, The Graph subgraph and the mainnet deployment, and extended the escrow contracts (ERC-721 claims, Kleros arbitration interfaces).
  • Solo-built "Struction," a tokenized real-estate / RWA shares platform (ERC-20 shares + The Graph subgraph + Next.js), deployed to Sepolia.
