Maksim Tkachev

I’m a Senior SDET / QA Lead with 15 years of experience building and scaling quality engineering practices across startups and enterprise environments. I focus on stabilizing distributed systems and modernizing software delivery to improve reliability.

Across backend systems, data platforms, cloud infrastructure, and mission-critical services, I lead quality initiatives that connect engineering standards to measurable operational outcomes. I’m especially strong in automation, CI/CD, observability, and engineering best practices.

In my most recent role at Spirii A/S, I helped transition from a fragile JavaScript codebase to a structured TypeScript system, introduced automated testing and CI/CD pipelines, and containerized infrastructure using Docker and Kubernetes. I also implemented structured logging, monitoring, and tracing, improving incident response and production diagnosability.

At Grundfos Holding A/S, I owned end-to-end reliability for a mission-critical IoT platform, redesigning a failing monolith into modular, testable services and rebuilding data pipelines for near real-time sensor ingestion. I introduced retry logic and failure recovery to reach near 100% stability, improved performance by ~3x, and supported scalability decisions via large-scale load testing.
