Péter Berekvölgyi

Senior software engineer (~10 yrs). Production agentic AI · Backend systems · Web3.

About me

  • 🤖 Currently shipping production agentic-AI systems at R34dy zrt. on the Claude Agent SDK and Pydantic AI for analysis of large enterprise codebases and documents. Dozens of parallel subagents with per-server MCP wrappers, Milvus graph-RAG, Logfire + Opik observability, and output-validation guardrails driving retry-with-feedback loops.
  • 🧠 Founding engineer at Mercury Protocol — decentralized AI-training network that proves this model was trained on this code and this data without trusting the node operator. Co-designed the protocol; built the off-chain node MVPs (see mcy-sgx-gramine below).
  • ⛓️ Web3 / smart contracts (Cyfrin Updraft coursework) — Solidity, Foundry, EVM. Pinned: collateralized stablecoin with Foundry invariant testing + Slither in CI, Sepolia-verified. Full course index in Learning & coursework.
  • 🛠️ Previously: backend at CoinPanel (multi-exchange crypto trading on GCP, 8 exchanges including Binance/Coinbase/Kraken, FastAPI + asyncio + Bigtable + Pub/Sub, thousands of paid subscribers); backend at Finmatics (Django / PostgreSQL bookkeeping platform); solo crypto trading bot (side project); embedded ASIL-D automotive C at thyssenkrupp (electric-steering systems).

Selected work

  • mcy-sgx-gramine — Mercury Protocol's off-chain node MVPs. Two building blocks: mcy_dist_ai (PyPI) — synchronous data-parallel PyTorch training over file-based IPC — and a Gramine SGX enclave with EPID remote attestation and ECDH/Fernet-encrypted data + model channels. Python · Intel SGX · Gramine · asyncio · multiprocessing.
  • dotclaude — How I work with Claude Code: rules, skills, sub-agents, hooks, daily-loop MCP servers (context7, sequential-thinking, claude-context, serena). Symlinked into ~/.claude/ so changes propagate across every project I touch.
  • cyfrin-advanced-foundry-defi-stablecoin — Exogenously-collateralized USD-pegged ERC20 stablecoin in Foundry. Over-collateralized 200% with WETH/WBTC, Chainlink-priced, 10% liquidation bonus. Foundry invariant testing · Slither in CI · Sepolia-verified.

Learning & coursework

  • cyfrin-foundry-projects — Index of completed Cyfrin Updraft project repos (AA, CCIP, DAO, ERC20, Merkle airdrop, NFT, VRF lottery, stablecoin, UUPS).
  • webservice-template — Opinionated Flask / SQLAlchemy / PostgreSQL backend template (Docker Compose + Kubernetes / minikube).
