Summary
👤
Senior🎓
Top SchoolNikita Zarubin is a solo founder and product engineer with 13+ years of backend experience who builds AI products end-to-end, from LLM infrastructure and multi-GPU optimisation to billing, analytics, and growth. He combines deep PHP/Laravel roots with modern large-scale system design, having scaled an in-house vLLM stack to ~10,000 tokens/sec and operated production Stable Diffusion and video-generation pipelines. Nikita moves fast—shipping an MVP in a week, a mobile app in three weeks, and driving a product to break-even and $10k MRR within months—while keeping codebases clean and production-ready. He blends engineering, product, and monetization expertise to boost ARPU through AI-assisted analytics and data-driven experimentation. Based in Novi Sad, Serbia, he’s as comfortable optimizing SQL and CI/CD as he is designing agent integrations and custom LoRAs, making commercially viable AI systems rather than just research demos.
