• 290+ production systems delivered
• 200+ clients served globally
• Shipped and maintained multiple production systems across Web3 and backend stacks
• Experience across on-chain, off-chain, infra, and automation pipelines
• Deep focus on protocol-level design and system reliability
• Comfortable owning architecture from design → deployment

I work independently { and in teams ;) }, owning architecture, implementation, optimisation, and deployment across complex real‑world systems.
My focus: build fast, build reliably, build things that scale.

• Designing robust on‑chain & off‑chain systems
• Building composable tooling for EVM / Cosmos / Solana ecosystems
• Engineering reliable, high‑performance backend & infra patterns
• Exploring AI‑powered automation & intelligent tooling
• Experimenting with cross‑chain logic, simulations, and system patterns

Solidity • JavaScript • TypeScript • Python • Rust • Bash • C / C++ • R • Go (WIP)

• Web / Backend: Next.js • Express • FastAPI • Flask
• Web3 / Blockchain: Hardhat • Foundry • CosmWasm • Ethers.js • Web3.js
• Rust / Systems: Tokio • Serde • Actix
• Frontend: React • Vite • Tailwind
• ML / Data: scikit‑learn • TensorFlow • Keras • ONNX
• Agents / Automation: n8n • Custom RAG-style pipelines • LangChain‑pattern architectures

EVM • Cosmos • Solana

PostgreSQL • MySQL • MongoDB • Redis

Linux • Docker • Nginx • Kubernetes (WIP)

• Small composable primitives > giant monoliths
• Deterministic behaviour → reliability
• Clarity > cleverness
• Ship fast, never compromise architecture
• Developer empathy is a superpower
