Valentin

Tech Lead and System Architect with over 12 years of experience in software development and team leadership. Throughout my career, I’ve built development departments from scratch, led cross-functional teams of up to 60 people, and overseen projects involving complex architecture and high-load systems. I’ve designed and implemented data platforms exceeding 300 TB in scale, and developed payment systems with over 2 million daily active users and more than 5,000 transactions per second. My focus areas include backend development, data engineering, and system architecture. I work confidently with Python, Django, PostgreSQL, Greenplum, Kafka, Airflow, Docker, and RabbitMQ. I’m deeply involved in pre-sales, architecture planning, mentoring junior specialists, and aligning tech solutions with business strategy. I thrive in environments where I can combine technical depth with long-term thinking and team growth.
