What I'm looking for

I’m looking for a role where I can own data quality end-to-end, automate reporting with GenAI/LLMs, and build BI dashboards and ML-powered insights that improve operational decisions.

I’m a Computer Science graduate with hands-on experience building data quality pipelines, fine-tuning and evaluating machine learning models, and turning data findings into insights the business can act on. I’m comfortable using Python for data cleaning, data profiling, and EDA on datasets of 200,000+ records, and I build dashboards in Looker Studio for real-time operational monitoring.

In my role at the Indonesian Hajj Affairs Office, I performed exploratory data analysis on 870+ pilgrim reports to identify complaint patterns, then translated results into 2 real-time Looker Studio dashboards. I automated daily reporting and documentation with Google Apps Script and built a Python pipeline to extract and clean data from the Kawal Haji platform, supporting consistent, accurate dashboard inputs.

As a Data Scientist Intern at Ananas Insurance, I built a Python pipeline using Gemini Embedding (Google API) to audit mapping tables and improve cross-lingual matching (Arabic/English) across key fields with 96%+ accuracy. I also developed automated data quality reporting with an LLM (Qwen) and delivered a production-ready pipeline the data team now uses—backed by a habit of keeping work well documented.
