Where I've worked

Noah

Senior Core Engineer — Blockchain & Backend Infrastructure

September 2025 – Present
Remote
GoTypeScriptAWS CDKGraphQLDynamoDBQuickNodeFireblocksStep FunctionsLambda
  • 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

February 2025 – September 2025
Remote
GoSolidityDockerAnvilGethCI/CD
  • 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

January 2023 – January 2025
Remote
GoCosmos SDKRustCosmWasmSoliditygRPCProtobufGrafanaDockerKubernetesGCP
  • 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

June 2021 – January 2023
Dubai, UAE & Bangalore, India
GoCosmos SDKIBCICAICQgRPCProtobufKafkaDockerKubernetes
  • 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
