Nikita B.

I help companies build software that is difficult to build. With 20+ years of hands-on engineering experience—including CTO and Head of Engineering roles—I design, build, modernize, and scale complex software products. I've worked with startups, fast-growing SaaS companies, trading firms, and enterprise organizations, leading projects from idea to production. My experience includes AI-powered applications, trading and fintech platforms, SaaS products, cloud-native systems, backend architecture, automation, and engineering leadership. I still write production code every day and enjoy solving challenging technical problems. Whether you need an MVP, a production-ready platform, AI integration, system modernization, performance optimization, or technical leadership, I can take ownership of the entire engineering process—from architecture and implementation to delivery. Core expertise: • AI Agents, LLMs & Automation • Trading & FinTech Systems (FIX, Market Data, Risk) • SaaS Platforms & Cloud Architecture • Java, Python, Node.js, TypeScript • AWS, Docker, Kubernetes, PostgreSQL • CTO / Fractional CTO / Engineering Leadership I prefer long-term partnerships where I can make a measurable technical and business impact.
