Infrastructure and protocol engineer. I work across Rust and Go on compilers, consensus clients and SDKs, and I run validator, node and prover infrastructure across a long list of networks. The contributions I'm proudest of are the small ones that are awkward in the reasoning — error paths, lifecycle bugs, feature-gating, rounding.

I contribute upstream rather than only building my own things: 39 merged pull requests across 20 public repositories, all tested against each project's own suite and merged through its normal review process.

tangle-network/blueprint — 15 merged PRs to the Blueprint Rust SDK (cli/src and the no_std crate stack). CLI error surfacing, subprocess lifecycle, --init scaffolding, keystore fail-closed behaviour, tracing, release tooling.

starkware-libs/cairo — #10458, #[must_use] now honoured on impl methods in the semantic layer, with a diagnostic test.

celestiaorg/celestia-node — #5349, removed a panic on a nil TxConfig in the state package, normalising to defaults across the tx-client path.

celestiaorg/celestia-core — #3383, prevote draining before precommits are injected into the consensus test state.

IntersectMBO/mithril — #3566, conversion coverage across the halo2 IVC proof system.

genlayerlabs/genvm-manager — 4 merged PRs: failed-to-start handling, run and semantic-validation ordering, a shared cross-major test harness.

Also merged in: gluwa/creditcoin3, pushchain/push-chain-wallet, FhenixProtocol/cofhesdk, tkhq/qos, NousResearch/atropos, vlayer-xyz/vlayer, bandprotocol/bandchain-docs, 0xMiden/tutorials.

Flip the Switch (WeMakeDevs × Switch) — agent invitation policy for a shared room-service layer: one shared check reused by every invite path, an unverified-join path that admits but announces, and tests for each. Implemented against the maintainer's written policy, tested against the project's own suite, and prepared for the November PR window.

Stocklana — streamdividend: a dividend-streaming vault for tokenized stocks on Solana. Hold AAPLx, earn its real dividends in USDC pro-rata, on-chain. Mainnet-live, Pyth Lazer price feeds, self-audited.

PayPal AI Hackathon 2026 — amanah-paypal: an autonomous, auditable treasury agent for charities on PayPal rails.

HackCanton S4 — provenance: payment holds where the honesty rule is enforced by the ledger, in Canton/Daml.

Graph Hacks 2026 (WeMakeDevs × FalkorDB), Agents Track — graphhacks-refusal-agent: an agent that walks a FalkorDB call graph, finds an exploit path, refuses to certify it, and files a BLOCKED CertificationRequest. graphhacks-patchweaver.

Cairo — the #[must_use] compiler fix above started as a hunt through the semantic layer for unreported attributes.

Security review — reading code with a specific question in mind and refusing to call something a bug until a runnable artifact proves it: a candidate finding only counts when a command fails on the current tree and passes once repaired, and the demonstration has to name the real file it is about. Findings submitted through HackenProof, Guardian Defender and Sherlock.

streamdividend — dividend-streaming vault for tokenized stocks on Solana. Mainnet-live.

claimscout — finds open-source issues actually worth your time: deterministic triage plus open-weight-model ranking. Python.

holdwatch — PayPal payout holds and account restrictions explained the moment they happen. Webhook receiver with signature verification and concrete next actions. Python.

provenance — payment holds where the honesty rule is enforced by the ledger. Canton/Daml.

auditgraph — smart-contract vulnerability knowledge graph on FalkorDB. Python.

deathclock — verifiable inheritance on Solana: an estate releases on a zero-knowledge proof of absence (RISC Zero Groth16).

PharmChain — one-scan medicine verification on Monad mainnet.

washmap — crowdsourced water and sanitation facility mapping for Nigeria: report broken boreholes, contaminated water points and open defecation sites in real time.

I've run and still run validators, nodes, sequencers, provers, miners and workers across a long list of networks — testnet and mainnet, from bare metal.

SanitovaCheck — water, sanitation and hygiene risk assessment for Android (Kotlin). sanitova-resolve — environmental compliance disputes and parametric sanitation insurance through AI validator consensus on GenLayer. wash-risk-agent — WASH incident risk assessment on Alibaba Cloud Function Compute.
