Where I've worked
Noah
Senior Core Engineer — Blockchain & Backend Infrastructure
- ▸Extended Noah's blockchain transaction infrastructure by integrating QuickNode webhook pipelines alongside the existing Fireblocks custody setup — covering deposit-address registration, confirmation tracking, and settlement orchestration via AWS Step Functions
- ▸Designed and maintained gRPC-based Go microservices for on-chain event processing, including webhook pipelines with auth hardening, retry/backoff logic, and idempotency guarantees for payment flows
- ▸Implemented event-driven deposit monitoring and confirmation systems across EVM-compatible networks, with fee validation and safe production processing for crypto payment infrastructure
- ▸Expanded reliability through API and E2E test coverage; maintained generated types, mocks, and codegen wiring for stable cross-service deployments
- ▸Participated in on-call rotations and incident response for production blockchain infrastructure serving live payment flows
Catalysis Labs
Senior Blockchain Engineer — Core Infrastructure
- ▸Built a production-grade Go SDK from scratch for constructing AVSs on EVM — including consensus engines, P2P networking, ECDSA/BLS cryptographic schemes, and execution engines; shipped v0 with 80%+ test coverage
- ▸Engineered distributed system primitives: idempotent task execution, distributed coordination patterns, and robust error handling across multi-node environments
- ▸Built an integration test suite with live Anvil instances, multi-node deployers, and automated Solidity contract deployment and binding generation
- ▸Created Lumos CLI for developer tooling — covering operator registration, project scaffolding, network management, and relay system coordination
- ▸Established CI/CD pipelines, Docker containerization, and build systems for a team shipping EVM smart contract + Go infrastructure
Quasar Labs / Tower
Senior Blockchain Engineer — Chain Infrastructure & Smart Contracts
- ▸Contributed to TowerDex — a Rust-based DEX currently deployed on Babylon mainnet with $31M+ TVL (at peak) — from ideation through architecture and deployment
- ▸Owned all chain operations: planned and emergency upgrades, governance proposals, node maintenance, IBC relayers, and chain state management across testnets and mainnet
- ▸Built and maintained CosmWasm-based concentrated liquidity and LP vault smart contracts on Osmosis; deployed and maintained EVM vaults on Sepolia testnet and Arbitrum mainnet
- ▸Designed and implemented transaction state machines, monitoring systems, and alert pipelines for continuous production observability across company products
- ▸Sole contributor on E2E and Kubernetes-based testing environments replicating mainnet conditions; created Vault Based Incentives (VBI) — a new merkle proof-based incentives product
- ▸Built monitoring and alerting infrastructure using Grafana, Firehose, and Graph Protocol indexers for real-time chain and vault anomaly detection
Persistence One
Blockchain Developer — Cosmos SDK & IBC Infrastructure
- ▸Played a significant role in shipping pStake liquid staking v3 — built on IBC, ICA, and ICQ — which accumulated $5M+ TVL within a month of launch
- ▸Built and maintained the liquid staking module and orchestrator for v2 (CosmosSDK module), implementing signature aggregation, IBC packet handling, and RPC/gRPC communication patterns
- ▸Maintained pBridge between Ethereum and Tendermint-based chains; deep experience with cross-chain message passing and finality handling
- ▸Created robust CI/CD pipelines and Kubernetes-based testing environments designed to replicate mainnet behavior; managed mainnet/testnet upgrades for PersistenceOne (XPRT)
- ▸Contributed to PersistenceSDK — an open-source Go framework for composable Cosmos blockchain modules, currently AssetMantle
