Summary
Sergii Kirianov is a pragmatic software leader who combines five years of product engineering experience with eight years at sea as a navigation officer, most recently as Second Officer on LNG carriers for Shell Nakilat. He’s built and scaled an AI-powered EdTech platform to 60,000 users (web, React Native, Node/Postgres, multi-model LLM orchestration) and has driven developer experience work that cut onboarding time from days to minutes. Sergii applies disciplined operational rigor from maritime incident response to deliver 99.9% uptime, major cost optimizations, and resilient migrations in production systems. He publishes open-source tooling for LLM browser agents (dom-distill) that dramatically reduces token bloat and is deeply experienced in TypeScript, React, Node, and AI/LLM stacks. Based in Calgary, he uniquely bridges domain knowledge in maritime and energy with hands-on engineering and technical leadership, making him a strong fit for maritime-tech, AI products, or developer tools roles.
