Background

About Serhii Olifir

I’m an engineering manager who still ships code. Over the past 10+ years, I’ve built full-stack features, architected async backends, rewired legacy systems, and helped SaaS teams deliver faster with fewer headaches. I currently lead engineering at Entromy — planning sprints, shaping architecture, mentoring devs, and writing code every week. I’m hands-on with everything from feature breakdown to final PR. Some highlights: – Built a custom async engine powering analytics across the platform – Rewrote our PowerPoint report generator in Python with reusable components – Slipped service-based architecture into a legacy Java backend – Built NLP-based moderation for open-text inputs using OpenAI + Azure APIs – Started the backend migration to NestJS and shipped the first real pieces I move fast, cut scope when needed, and value code that’s boring, readable, and hard to break. Looking to connect with startups solving real problems — or folks who care about good engineering.
