At 01.tech, I led a Snowflake-to-ClickHouse data warehouse migration that cut costs by 70% and saved $2M+ annually. I also helped accelerate the data platform from zero releases in six months to eight releases per week.
I rebuilt the Kanban system around the real Jira workflow, making delivery more predictable for 40+ dependent teams across seven data units. I also introduced flow metrics and tailored coaching that improved lead time by 20–30%.
At Softswiss, I launched three B2B products from scratch, with each MVP delivered within two months, and coordinated delivery across product and data teams. I established a data team of more than 15 people while maintaining turnover below 10%.
Earlier, at 21vek.by, I led an eight-member cross-functional team to launch an e-commerce site that generated $8M in quarterly revenue. My work also included implementing Kanban, increasing deployment frequency, and optimizing product flows through A/B testing.
