Hi, my name is
Vlad Kost
Senior Software Engineer · Engineer. Founder. AI-Native Builder.
I build backend systems at scale and ship products with AI. Previously at Google, now founding three businesses.
About
I'm a Senior Software Engineer with 10+ years of experience building backend services, APIs, and distributed systems in C#/.NET and Java. I spent 4 years at Google shipping production systems at scale — from integration test infrastructure across all Workspace products to performance tooling for Google Assistant.
After Google, I went full-founder mode — launching three businesses: an AI consulting practice helping engineering teams adopt AI-native workflows, a multi-tenant SaaS platform built entirely with Claude Code on PostgreSQL, and a luxury beauty brand powered by AI across every operational surface.
I believe the best engineers don't just write code — they own outcomes. I care about architecture that lasts, systems that scale, and shipping things that matter. I use AI as a daily accelerator, not a crutch.
