Artificial Intelligence (AI) is changing how financial companies work. It helps detect fraud, predict credit risk, and personalize services for customers. As a Senior System Data Analyst, I’ve seen how AI can turn complex financial data into useful insights that help businesses make better decisions and protect their customers.
What Data Analysts Do in AI and Fintech
Data analysts play an important role in making AI work. They clean and prepare data, create features that help AI models understand the information, and check how well models perform. They also explain results to business teams and help keep the AI models working well over time.
Common AI Uses in Fintech
- Fraud Detection: AI learns what normal transactions look like and spots anything unusual that could be fraud.
- Credit Risk Modeling: Machine learning predicts how likely a customer is to repay a loan by analyzing lots of data.
- Personalization: AI groups customers by their behavior so companies can offer services that fit their needs.
- Churn Prediction: AI helps predict which customers might leave, so companies can try to keep them.
Tools I Use
Some of the main tools I work with include:
- Python for programming
- pandas and NumPy for data handling
- scikit-learn, XGBoost, and LightGBM for machine learning
- imbalanced-learn to deal with rare fraud cases
- SHAP and LIME to explain model decisions
- Azure ML and AWS SageMaker for deploying AI models
Why Ethics Matter
AI affects real people’s lives, so it must be fair and transparent. I check models for bias and use tools that explain how they make decisions. This helps build trust with customers and regulators and ensures compliance with laws like GDPR.
What I’ve Learned
- AI models need regular updates to stay accurate.
- Human judgment is important alongside AI, especially for big decisions.
- Good communication between analysts and business teams helps AI succeed.
