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 decentralized web — not just as a technology stack, but as infrastructure that makes finance open, permissionless, and censorship-resistant. I've spent a lot of time building developer-facing SDKs and APIs, client-side applications, and backend services in this space.

I'm strong in system architecture and enjoy hands-on work on mission-critical features. I do my best work as a full-cycle individual contributor, solving hard non-trivial problems and shipping systems to production. I'm passionate about AI-driven development — working with Claude as my daily driver has boosted my productivity 10x, and I believe AI-first engineering is the future of how great software gets built.

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 state management library focused on functional reactivity — rxfy.
