A typical week in my work as a Data Scientist looks like:

• checking data quality issues before they break forecasts • debugging feature pipelines in PySpark • retraining models and tracking experiments in MLflow • explaining results to non-technical stakeholders • simplifying models so teams can maintain them

Most of the value doesn’t come from fancy algorithms it comes from making ML reliable.

If your team needs someone who can operate between data, product, and engineering: 👉 I’m available for freelance, or part-time collaborations.

I’ve recently opened up availability for operations support, quality assurance, and training/documentation work. My focus is helping teams improve consistency, clarity, and performance through better processes, SOPs, QA insights, and onboarding materials.

If your team needs support with workflows, documentation, QA evaluations, or training content, I’m available for project‑based or ongoing work. Clear processes and strong documentation make everything run smoother—happy to help you get there.
