Hi, I'm Andrey

I'm a backend engineer with over 15 years of experience building and scaling SaaS products. Currently, I'm the CTO at planfact.io — a profitable B2B company helping thousands of small and midsize businesses manage their finances efficiently.

At Planfact, I lead a 25-person engineering team and stay hands-on with architecture, infrastructure, and backend systems. Over the past years, I’ve driven key transformations:

• Migration from on-premise Windows Server to Kubernetes on Linux, improving scalability and reliability
• Design and rollout of a full observability stack (ClickStack + Sentry) achieving 99.998% uptime
• Adoption of Terraform + Ansible for reproducible IaC environments
• Reference modular architecture for all backend services (.NET 9)
• Migration of core services from .NET 6 → 9, Angular 15 → 19
• Building a remote-first engineering culture with RFCs, async communication, and strong ownership

Transition and Focus

My current professional focus is on AI Infrastructure and Inference Engineering — where backend systems, cloud-native infrastructure, and machine learning serving converge.

I’m building hands-on expertise in:

• LLM and model serving (vLLM, Triton, Ray Serve)
• Observability and performance for GPU inference workloads
• Distributed systems and scalable compute pipelines
• Infrastructure as Code, container orchestration, and reproducible environments

My long-term goal is to contribute to frontier AI labs and help scale intelligent applications from research to reliable production systems.

Background

Before Planfact, I worked in startups and enterprise environments across Germany and Russia — from fintech and data privacy to retail and media.

Some highlights include:

• Statice.ai — Designed backend and infra components for a data privacy platform (Python, FastAPI, K8s, GCP)
• X5 Retail Group — Launched food.ru, #1 media platform about food in Russia, awarded Runet Prize 2021
• Clark.de (Series A) — Built integrations with N26 Bank, enabling in-app insurance sign-up
• Payler — Designed and launched a payment gateway, transforming the company into an international payment provider

Education

Master’s degree in Applied Mathematics and Computer Science from Bryansk State University. Since 2024, I’ve been continuously expanding my knowledge in ML systems and AI infrastructure design.
