Senior overengineer, DeFi builder, cypherpunk enthusiast, occasional thinker and a little bit of writer. Based in Moscow → Lisbon.
Hi, I'm Ivan — a software engineer with 10+ years of experience building well-designed, production-grade codebases. Many systems I've built from scratch are still running in production today. I've been a founding engineer at startups that raised $17M in funding and are still operating.
Most of my career has been spent building decentralized applications on Ethereum. I'm deeply invested in the decentralization technologies — not just as a technology stack, but as a new rails that makes finance open, permissionless, and censorship-resistant. I've been building developer-facing SDKs and APIs, client-side applications, and backend services in this space.
I'm strong in system and codebase architecture and design engineering. I do my best work as a full-cycle individual contributor, solving non-trivial problems and shipping products to production.
I follow SOLID principles with a strong focus on static type-safety using TypeScript. I combine functional-reactive programming and pragmatic OOP to keep codebases lean and easy to extend. I'm especially fond of RxJS and currently building my own model/store/state management framework focused on functional reactivity and state normalization — rxfy.
Let's connect, I will design
UI = ƒ(query)(data) & query = ƒ(state)
