Senior data scientist shipping ML systems that lift conversion and revenue.
What I'm looking for
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.
Experience
Work history, roles, and key accomplishments
Led a cross-vertical recommendation engine across 5-variant A/B tests, driving $1M incremental order value and a 13.2% YoY conversion lift. Shipped multiple ML initiatives including location-of-interest modeling, an LLM email/WhatsApp parser at 99% accuracy/98% automation, and learning-to-rank hotel re-ranking (+69% conversion, +43% GBV).
Data Scientist
Elmenus
Sep 2021 - Oct 2022 (1 year 1 month)
Built an implicit-feedback collaborative filtering recommender, improving conversion by 7% and speeding time-to-discovery by ~1 minute per session. Developed an order-delay prediction system (81% precision/79% recall) to reduce cancellation rate by 3% and lower monthly lost-order costs.
Data Scientist
FiveRivers Technologies
Feb 2020 - Aug 2021 (1 year 6 months)
Built and deployed a deep-learning video summarization tool that condenses long videos into 30-second highlight clips. Developed a pose-estimation-based basketball performance analysis system (>90% accuracy) and built prediction/optimization models for highway accidents (70% accuracy) and scooter dock placement (~7% profit gain in affected zones).
Data Scientist
Logicon
Dec 2018 - Feb 2020 (1 year 2 months)
Built and delivered a content-based job and course recommender end-to-end, including data collection, a Flask API, and the recommendation engine. Developed an abusive-content detector (94% accuracy) and a time-series demand-forecasting system that reduced inventory carrying costs for a retail client.
Software Engineer
Innovative Technology
Jul 2015 - Sep 2017 (2 years 2 months)
Co-built a question-bank platform for the Saudi Health Commission using PHP/CodeIgniter, supporting thousands of daily users, and developed a backend/front-end currency-exchange dashboard. Applied data-driven modeling to optimize scooter dock placement (~7% profit gain in affected zones) and built a highway-accident prediction system.
