Vadim

Sigaev

I am a senior software architect and technical leader with over 20 years of commercial development experience, working professionally since 2002. I design, launch, and scale complex production systems, taking full ownership from architecture and technical strategy to long-term stability in production. I have delivered large-scale products in e-commerce and retail, mobile-first consumer platforms, real-time blockchain analytics, on-chain and Web3 products, as well as gaming and GameFi projects. My expertise combines high-load distributed systems, transactional platforms, blockchain engineering, and large-scale mobile infrastructures. I act as a technical lead, architect, or fractional CTO, conduct deep code and architecture audits, strengthen engineering teams, and restart stalled projects. My core focus is security, scalability, and systems that remain stable under real-world load.
