krissemmy/README.md

Hi there 👋🏾 Welcome to my GitHub!

I’m Emmanuel (Chris), a DevOps and Blockchain Data Engineer focused on node infrastructure, on-chain data systems, and high-performance monitoring tools.

I’m building Krainode, an open RPC playground for testing and benchmarking multi-chain EVM endpoints.

Previously, I was a Founding DevOps & Data Engineer at GlueX Protocol, running multi-chain node infra and building indexing and monitoring pipelines.

👨🏾‍💻 I specialize in blockchain node operations, on-chain data indexing, and real-time monitoring systems.
💬 Ask me about: Running full nodes, building data pipelines, cloud infra automation, or monitoring stacks.

😄 Pronouns: He/Him
⚡ Fun fact: I love music, collect recipes to cook new dishes, and do my best work in with music and snacks to go.

🧠 About Me

I like building fast systems, debugging distributed infra, and making nodes behave. I enjoy open-source work and small tools that help other engineers ship faster.

🚀 What I Do

I work across the full infra stack for Web3:

  • Node Infrastructure: Ethereum, Arbitrum, Base, Blast, Linea, Scroll, Optimism, Polygon, Gnosis, BNB, Sei, Taiko, Hyperevm, Berachain, Sonic, Unichain.
  • RPC Performance: latency tuning, request routing, stress testing, benchmarking.
  • Indexing & Data Engineering: custom indexers (RDS + Dynamo), ETL/ELT pipelines, analytics-ready models.
  • Monitoring: Loki, Prometheus, Grafana, log pipelines, alerting, metrics.
  • Cloud Infra: AWS EC2, NVMe/EBS setups, autoscaling, CI/CD, cost optimization.

✅ Node Infrastructure Experience

I have hands-on experience or deep research knowledge in setting up and managing nodes across:

Ethereum, Arbitrum, Base, Blast, Linea, Scroll, Mantle, Polygon, Optimism, Gnosis, BNB Chain, Berachain, Unichain, Sonic, Avalanche, Sei, Taiko, and Hyperevm.
