About Sarah

Sarah brings over 15 years of software engineering experience to Vantade. She began her career as a backend engineer at Google, where she worked on large-scale distributed systems serving hundreds of millions of users daily. That experience gave her an instinct for building systems that don't just work — they work under pressure.

After Google, Sarah spent three years at a Series B fintech startup as VP Engineering before joining Vantade as CTO. She has led teams that built everything from payment processing infrastructure to real-time analytics platforms and AI-driven recommendation engines.

Her approach is pragmatic: choose boring technology where reliability matters, reach for cutting-edge tools only when the use case genuinely demands it. She writes code every week, keeps a close eye on performance metrics, and believes that great software is built by teams who communicate well — not just by individuals who code fast.
