About

Alexei Petrachuk outdoors in winter

I’m a backend developer passionate about building high-load server applications that combine robust architecture, performance, and scalability. I enjoy working on systems designed for stability and efficiency under extreme load—solutions capable of handling millions of requests with minimal latency.

Currently, I’m Head of the Data Integration Center at Russian Standard Bank, where I build and maintain core integrations that support decision-making and risk assessment. I’m also involved in designing and optimizing backend infrastructure to meet best practices in performance, security, and reliability.

I’ve built backend solutions across a wide range of teams — from large enterprises and startups to small groups focused on digital products.

In my free time, I enjoy running, cycling, reading technical books, spending time with my family, or honing my survival skills in battle royale games.
