What I'm looking for

I’m looking for a role where I own data-to-deployment ML problems end-to-end—recommenders, NLP/LLM-RAG, A/B testing, and MLOps—delivering measurable conversion/revenue gains at scale with strong stakeholder collaboration.

I’m a Senior Data Scientist with 10+ years in software and ML, focused on owning problems end-to-end—from data and modeling through deployment, A/B testing, and stakeholder alignment. I’ve shipped 7+ production data science solutions across recommendations, learning-to-rank, NLP, and LLM-powered systems, driving $5M+ in incremental Gross Booking Value and double-digit conversion lifts at scale.

My work is deeply hands-on: Python, PyTorch, and modern LLM/RAG stacks (LangChain, Hugging Face, vector stores), plus cloud serving on GCP and AWS. At Tiket.com, I led cross-vertical recommendation experiments (+13.2% YoY conversion lift), productionized marketing mix modeling (budget utilization 70%→98%, ~22% lower cost-per-DTU), built LLM parsing automation (99% accuracy/98% automation), and delivered dynamic pricing and ML security improvements—always with measurable, OKR-tracked impact.
