Owned the core financial machinery of a live perpetuals exchange.
- Funding and pricing. Designed the Virtual Funding Rate engine around open-interest imbalance, capped transfers between longs and shorts, and settlement across the position lifecycle. Built multi-provider oracle checks and the Rust price publisher.
- Execution. Authored Rust liquidation, stop-loss/take-profit and limit-order keepers with concurrent polling and authenticated HTTP triggers, deduplication and on-chain predicate checks. Co-developed the separate Yellowstone gRPC/Jito executor and operated the non-voting Solana RPC node.
- The product around the protocol. Shipped synthetic-market trading and liquidity flows, funding/revenue APIs and a reconciled referral-payout state machine. Hardened API authorization and added admin audit logging.
- Leadership and release responsibility. Led one engineer in a five-person team. Worked directly with both founders, including the CTO, and coordinated the quant's requirements with implementation and delivery.
Two independent execution paths submit to the same Solana program. I authored the polling/API keepers and co-developed the existing gRPC executor.

Failure boundary. Off-chain triggers request execution; the program decides whether it is valid. Oracle freshness and agreement checks remain on-chain.
Market expansion, oracle reliability and governed releases
Five synthetic markets, with real trading hours
Launched gold, silver, WTI, S&P 500 and NVDA perpetuals across contracts, market-hours services and the trading UI, including liquidity mint/redeem flows. Signed attestations gated trading when an underlying market was closed.
The oracle pipeline recorded roughly 94,000 signed price batches per day over an eight-week window. I split price writes from AUM consensus so a provider outage would not repeatedly revert the fresh writes. Versioned transactions and address lookup tables brought oversized oracle transactions within Solana's packet limit. RPC failover was designed around the protocol's seven-second freshness budget.
Audit remediation through governed releases
Triaged 33 Fidesium findings and patched 15, including a two-step admin handover with a 48-hour timelock. Authored the remediation report and documented verifiable builds released through DAO governance.
Volume and trader figures describe platform activity during my tenure, not growth attributed to me. Batch throughput is an estimate from database sequence deltas, not a count of confirmed on-chain transactions. Adrena wound down trading in 2026.
02 · VAULTS & SETTLEMENT
Diamond Pools
Co-founder, Contracts & BackendMay 2026 - Present · Mainnet beta
3pool roles
Betaflagship financial product
Built the vault and execution systems behind a pooled ORE yield product.
- Financial accounting. Architected the Rust/Anchor program for Mining, Staking and Protocol pools: NAV-priced shares, forward-priced settlement, reserved exit liquidity and migrations of live accounts.
- Claims that survive delayed payouts. Tracked shared inventory and preserved unpaid proceeds for the original sellers. Added keeper exposure limits valued at current token prices and custody reconciliation.
- Slot-aware execution. Built transaction scheduling, landing measurements and adaptive timing, with on-chain round/tile guards that allow repeated submissions without buying the same tile twice. Coordinated the live account migration and ABI/SDK changes.
- Data the product can use. Built chain ingestion and historical backfill into PostgreSQL, with cached REST/WebSocket APIs for the customer app and analysis.
The execution service submits guarded transactions. A separate data service turns chain history into queryable product data.

- Source · Solana RPCAccounts + round historyIngest observed chain data and backfill missing history
- Off-chain · PostgreSQLIndexing + reconstructionStore and reconstruct historical records; observed values take precedence
- Off-chain · REST / WebSocketAPIs → customer appCached queries, streaming updates and historical analysis
Accounting boundary. Settlement preserves reserved exit liquidity and unpaid seller claims. The keeper refuses unmeasurable balances rather than treating an RPC error as zero custody.
Accounting edge cases and the quant feedback loop
Making accounting match upstream behavior
Corrected conservation arithmetic to accept valid negative intermediate values, and adjusted harvest accounting to reflect SOL already returned by the upstream program. Unpaid seller claims remain attributed across capped payouts and later realization.
The keeper distinguishes an absent token account from an RPC failure. An unmeasurable balance takes a refusal and reporting path rather than being treated as zero.
From quant specifications to observable execution
In our three-person team, I implement the quant co-founder's models, reviews and execution requirements. Built versioned decision, settlement, cost and reconciliation telemetry, with 39 days of archived core exports for review and diagnosis. Execution tooling includes flight-time adaptation and sender probes, with configuration separating monitoring from optional execution paths.
Mining, Staking and Protocol are different pool roles. The beta is deployed on Solana mainnet; the archive demonstrates traceability, not uninterrupted uptime or investment performance.
03 · AUTOMATION & CUSTODY
WhiteKnight / Fatsats
Co-founder, Protocol & BackendAug 2026 - Present · Live on mainnet
~$500early revenue reported to date*
Delivered a live product across Rust/Anchor custody, a Node.js operator, PostgreSQL-backed middleware and most of the Next.js app.
- Consent enforced on-chain. Built the Rust/Anchor custody program with user-set fee ceilings, cumulative per-round spending limits and permissionless collection for the separate Sat Rush mining game.
- Strategy outside the custody boundary. Moved strategy into replaceable operators while preserving account layouts through a mainnet upgrade. Coordinated the changed instruction interface across ABI, SDK and clients.
- Recovery from chain state. Built Node.js settlement and ticket recovery independent of the database roster, plus accounting reconciliation and scheduled safety checks. Tested custody and claims in LiteSVM using Sat Rush mainnet bytecode and account snapshots.
Users authorize spending and fees on-chain. Operators choose strategy within those limits; custody validation happens before the upstream game is called.

- Off-chain · PostgreSQLMiddleware → appServe operator telemetry and a signed preference-control channel
Independent collection. Wallet → permissionless claim → user-controlled protocol account. This path remains available without the chosen operator.
Product ownership and operator recovery
Across the stack
Built the program and operator services, public ABI and TypeScript SDK, PostgreSQL-backed telemetry middleware, and the majority of the Next.js frontend. The app covers wallet onboarding, miner settings, deposits, withdrawals, collection, recovery and history.
WhiteKnight is the protocol. Fatsats is its first operator and customer app. Sat Rush is the upstream game we integrate.
Runbooks backed by accounting checks
Documented operator startup, recovery and production operations. Configured 15-minute safety checks and hourly book-versus-chain audits, plus discovery of tickets directly from on-chain accounts after database loss.
*Approximately $500 in early revenue, reported as of September 10, 2026. This is a product milestone, not monthly revenue, profit or audited financial reporting. Check intervals describe the configured schedule.

04 / The person
There’s a life around the work.
Some of the things that make this place mine.
A PERSONAL NOTE
The point is the people.
Family is a big part of why I build. I want to make life easier for the people I love, be present for them, and have time to enjoy life together.
I love bringing friends into the same room. Hearing everyone’s story. Making sure there’s enough food, a good atmosphere and another seat at the table.
I make time for community work and food distribution. Practical care matters to me.
I like pressure in the work.
I like warmth in the room.
Personal settings
NO DEFAULT PRESET- 01 / On repeat
- Stutter EDM. Uplifting music. Something that keeps moving.
- 02 / On the workbench
- Linux, open computer cases and tiny chip repairs. I want to know what’s happening underneath.
- 03 / Down the rabbit hole
- Astrophysics, hardware and other people’s stories. There’s always another question.
- 04 / Everyday uniform
- Black or white tee. Shorts. White sneakers. White and graphite gadgets.
- 05 / Mechanical obsession
- The Pagani Huayra R Evo. The feeling of a machine with every detail considered.
- 06 / At the table
- Sushi, friends, good music. You’re welcome to pull up a chair.
I like people who take initiative, say what they mean, and stay curious about each other.
LESS GUESSWORK. MORE TRUST.THE DOOR IS OPEN
A hard problem?
A good story?
I’m open to protocol engineering and technical leadership roles.
I’m also happy to meet someone curious. Say hello.
