About Me

Who I Am

Senior Data Scientist building production AI

I'm a Senior Data Scientist at McKinsey & Company based in London. I specialise in deploying LLM-powered applications, agentic workflows, and machine learning systems end-to-end — with a strong focus on real-world delivery and client impact.

Beyond consulting, I co-founded QApture Ops — a production AI platform for automated mobile game QA using multimodal agentic AI (OpenCV, YOLO, PaddleOCR, GPT, Claude). I also co-founded Eminence Games, publishing mobile games and apps on iOS/Android.

I hold a BSc in Industrial Engineering from Bogazici University, ranked in the top 0.01% nationally. I combine mathematical rigour with engineering pragmatism to ship things that work.

Production AI Systems

LLM workflows, agentic pipelines, computer vision — deployed end-to-end, not just notebooks.

Real Business Impact

118% margin improvement, 70% hour reduction, 20% pick-pack efficiency gains — at McKinsey, Getir, Infarm.

Full-Stack AI Delivery

From FastAPI backends and Celery workers to Next.js dashboards — I own the full stack.

10+ Hackathon Awards

ING, SAP, Turkish Airlines, Euroleague — proven record of building fast under pressure.

Experience

Professional Experience

  • Built an LLM workflow to interpret legacy property deeds and store structured outputs in PostgreSQL. Led 2 engineers to deliver backend and appraiser dashboard.
  • Led end-to-end data platform migration for 2 clients — medallion architecture, Power BI dashboards for business users. Led team of 4 engineers through development and deployment.
  • Built elasticity-based pricing engine transitioned to production — contributing to 118% quarterly realised margin improvement.
  • Led geospatial analytics, footprint optimisation, M&A opportunity modelling, and mixed-integer optimisation for cost reduction across retail and PE clients.
