👋 Yevhenii Panteleimonchuk (@panteleymonchuk)

Fullstack Engineer & Tech Lead. 10+ years shipping web3, fintech, and SaaS products.

I build web products end-to-end — from WebGL rendering engines and hardware wallet integrations on the frontend to NodeJS/Go/Rust services on the backend. I'm business-oriented: I care about the outcome behind every task, and I work as a partner with founders and product teams to get there together. Along the way I've led engineering teams, run customer discovery, and used AI to make teams ship faster.

Expertise

• Business-oriented: Treat engineering as a lever for business results — take full ownership of tasks and act as a partner to founders/product, driving outcomes together
• Fullstack: 10+ years across web3, fintech, healthtech, and SaaS — architecture to delivery
• Blockchain/Web3: Wallets, dApps, explorers, hardware wallet integrations, multisig, supply-chain platforms on DID/VC standards
• Leadership: Led 3 engineering teams (4–6 engineers each) across 15+ client projects; 50+ hiring interviews
• AI & Tooling: multi-agent AI development workflows where team shipped 20% more features without adding headcount

Technical Stack

• Frontend: TypeScript, React, Next.js, WebGL
• Backend: Node.js, Go, Rust, Python

• Chrome Wallet Extension — non-custodial browser wallet from zero, multisig support, client-side key security
• dApps for ecosystem* — iota-names (marketplace for nicknames), dashboard (managing assets), migration tools
• Supply Chain Platform — blockchain-based platform for ports and logistics operators, built on ODRL / W3C DID/VC
• IOTA SDK 2.0 — update by upstream changes, cross-team sync, shipped in under 3 months, 95% OKR completion
• Hardware Wallet Integrations — Ledger, Keystone, signing flows end-to-end

Track Record

• Delivered 15+ client projects leading 3 cross-functional teams
