What I'm looking for

I seek a role that fosters innovation and collaboration, with opportunities for growth.

I am a Senior Python Developer with extensive experience in developing high-load services and infrastructure solutions for FinTech and e-commerce. My expertise lies in microservice architecture, integrations, and performance optimization, having built products utilized in over 20 countries, including China and Kazakhstan. Notable achievements include creating a cloud-based software update service that reduced support load eightfold and implementing a Kubernetes monitoring system for rapid failure detection.

Throughout my career, I have focused on optimizing system performance, notably reducing PostgreSQL query execution time from seconds to milliseconds and improving API latency by 40%. I thrive in cross-functional Agile teams, actively participating in strategic architecture planning, code reviews, and mentoring. My commitment to quality is reflected in my use of CI/CD, Terraform, and automated testing to ensure reliable and fast service deployment.
