Professional summary

I am a Senior Analytics Engineer and Modern Data Stack specialist with more than nine years of experience building cloud data pipelines, transformation layers, semantic models, and executive-facing business intelligence solutions.

I specialize in SQL, Python, dbt, BigQuery, Snowflake, Looker, and Power BI. My work focuses on turning complex raw data into governed, reliable, and self-service analytics products for technology and B2B SaaS organizations.

I have extensive experience auditing and refactoring cloud data architectures, optimizing query performance and compute costs, and implementing robust data governance controls such as row-level and field-level security.

I partner closely with product, engineering, analytics, customer success, sales, marketing, and executive stakeholders. I translate business requirements into scalable data models, dashboards, reporting workflows, and actionable performance insights.

I am experienced in SLA-driven support, root-cause analysis, technical documentation, data catalog management, and stakeholder communication across globally distributed teams.

I am open to remote opportunities worldwide and can collaborate across UTC+6, US, and European time zones.
