What I'm looking for

I’m looking for a role where I can build scalable dashboards and ML/GenAI solutions, collaborate cross-functionally in Agile teams, and turn complex data into measurable business outcomes for customers and stakeholders.

I’m an impact-driven Data Scientist and Analyst with 7+ years of experience turning complex data into strategic insights that drive growth, efficiency, and customer impact. I build machine learning models, automate analytics with Gen AI (Claude, GPT, and Gemini), and translate ambiguity into clear, actionable recommendations through strong data storytelling and visualization.

In recent roles, I’ve designed real-time Power BI dashboards using DAX, SQL, Python, and BigQuery, and engineered ETL processes and data pipelines on Azure and BigQuery to support data-driven decision-making. I’ve led KPI dashboard development, introduced automation that reduced reporting time by 40%, conducted A/B testing, and strengthened data quality through validation and cleaning (including Pandas). I enjoy collaborating across teams, supporting Agile scrum events with Jira, and delivering measurable outcomes that align analytics to real business goals.
