Ashkan Sheikh Ansari

I am a Data Analyst and Machine Learning Engineer with a strong background in developing production-grade models for fraud detection and credit risk assessment. With an MSc in Artificial Intelligence from Brunel University London, I have successfully delivered models that achieve 92% recall and 89% accuracy across over 10,000 daily transactions. My expertise lies in utilizing Python, SQL, and various machine learning frameworks to drive data-driven decision-making.

Throughout my career, I have worked with Outlier AI and Tejarat Bank, where I have honed my skills in data cleansing, model building, and automation. Notable achievements include building an XGBoost fraud-detection pipeline that prevented approximately £1.2M in annual chargebacks and automating daily credit-risk reports, significantly reducing manual workload. I am passionate about leveraging data to create impactful solutions and continuously seek opportunities to enhance my skills in data engineering and machine learning operations.
