Nikita Churnusov

I'm a Senior Backend Engineer focused on building scalable distributed systems, high-performance backend services, and transaction-heavy platforms.

Over the past several years, I have worked primarily in iGaming, high-risk payments, and fintech-related environments, developing systems that handle large volumes of transactions, real-time events, and business-critical workflows. My core technologies are Go and Python, though I also have experience working with Node.js, React, cloud infrastructure, containerized environments, and modern microservice architectures.

My expertise includes backend architecture, API development, payment integrations, event-driven systems, message brokers, distributed services, observability, performance optimization, and production operations. I enjoy solving complex engineering challenges around scalability, reliability, concurrency, and system design.

I am particularly interested in opportunities involving payments, fintech, iGaming, trading infrastructure, distributed systems, and other technically challenging domains where backend engineering plays a critical role in product success.

I value ownership, pragmatic decision-making, strong engineering culture, and building systems that deliver measurable business impact.
