Микита Вавренюк

I’m a Data Analyst with 1.5+ years owning product and revenue analytics in B2B SaaS. I deliver analytics end-to-end—from raw data to executive dashboards—so teams have a reliable basis for decisions.

At my current role, I rebuilt a complex billing model into a clean MRR/ARR reporting framework adopted as the single source of truth for revenue. I also built a churn-prediction framework that flags 2–3 high-risk accounts each quarter, directly retaining ~$120,000 in ARR over 12 months.

I ship production-grade pipelines and monitoring: a Python ETL and time-series system tracking 30+ product, billing, and integration metrics, plus anomaly detection that reduced time-to-detection of critical issues from days to under an hour. I’ve also shipped 10+ executive dashboards and ad-hoc analyses, and I use Claude/LLMs daily to accelerate SQL generation, EDA, and code review while ramping quickly on new domains like payments and fintech data.
