Summary

Senior🎓
Top SchoolMark Omarov is a Senior Product Engineer with a decade of experience shipping end-to-end web products and nine years based in Tokyo, currently leading technical implementation of new AI product lines at Cogent Labs. He combines hands-on TypeScript/React/Next.js work with infrastructure skills many product engineers avoid—CI/CD, IaC, observability, AWS, and container orchestration—so he owns UI, API, data model, deploys, and monitoring. Notable wins include leading a booking-automation platform at Travelport used by all EU-based travel agencies, zero-downtime DB migrations and CI/CD overhauls at Asurion, and shipping greenfield products and document pipelines that power RAG and search for ML features. He treats LLMs as engineering components, built a NestJS/Kafka/S3 document-serialization service for ML consumption, and contributed to open-source observability tooling (HyperDX). Fluent in English, Ukrainian and Russian and learning Japanese, he runs a homelab and open-source developer tools that consistently speed prototyping and improve developer experience. Open to senior IC or tech-lead roles, he optimizes for high-leverage teams and competitive compensation.
