Webomage builds and maintains blockchain and web3 backends, from infrastructure to smart contract integrations and DApp support.

Focus Areas

  • Ethereum-based applications using web3.py and related tooling
  • Wallet creation, transaction signing, and secure key management
  • Smart contract integrations, ICO/sidechain scenarios, and DeFi protocols
  • Indexing and analytics with The Graph (subgraphs) and related services
  • Running and maintaining blockchain nodes and supporting infrastructure

Example Work

  • Ripple/Stellar and Hyperledger Sawtooth
    Participated in crafting and deploying Ripple/Stellar verification nodes and Intel/IBM Hyperledger Sawtooth–based universal blockchain systems.

  • DeFi platforms (TokensFarm, DcentraLab, 2key Network)
    Developed DeFi backends with Python (web3.py, eth-abi), integrating with Ethereum nodes and smart contracts. Implemented subgraphs, DApp APIs, and CI/CD for blockchain workloads.

  • Web3 integrations & infrastructure hardening
    Solved complex web3 issues around nonce handling, gas spikes, and provider behavior. Migrated shared IPFS to dedicated storage, hosted The Graph instances, and hardened RPC nodes.

Typical Deliverables

  • Backend services and APIs for DApps and DeFi platforms
  • Infrastructure on AWS/Kubernetes tailored for blockchain workloads
  • Monitoring and alerting around node health, transaction flows, and contracts
  • Secure integrations with third-party APIs (Coingecko, 1inch, DexGuru, DefiLlama, etc.)
