What I'm looking for

I’m looking for a role where I can build and improve BI/data systems, strengthen analytics (segmentation, LTV, tracking), and apply ML/LLMs to drive measurable decision impact, while collaborating closely across product, engineering, and business stakeholders.

I’m a Data Analytics Lead and Data Engineer who builds decision-ready data systems—from BI dashboards to event tracking and unified data platforms. At Pupu Technology, I built the department’s data system from scratch, improving decision-making efficiency by 20% through a user operations metric framework and BI platform.

I’ve also led lifecycle value modeling with Random Forest and rebuilt event tracking to raise event recognition accuracy from 85% to 97%. In my current independent AI applications work, I lead an automated long-form novel generation workflow with LLMs—optimizing prompt orchestration to cut inconsistencies and boost generation efficiency by ~40% through iterative evaluation.
