I am working as a Back-End Engineer at BEAT (Better Environment and Transportation) since Oct 2025 🌍.
🎯 Aspiring Data Scientist & AI Engineer, certified by DataCamp
🎓 BSc in Astrophysics with Space Science (1st Class)
I started by studying galaxies, but found my real passion in data-driven discovery. Today, I design end-to-end ML projects from raw data pipelines to interactive dashboards that reveal insights and drive smarter decisions.

✨ Currently focused on:
- ⚡ Scientific Computing & Simulation : Transportation sector
- 🧠 LLMs & Generative AI: Hugging Face, fine-tuning transformers
- 📈 Time-Series Forecasting: LSTM, CNNs, SARIMAX for predictive analytics
- 🔎 Interpretable ML: SHAP, LIME for model transparency
📊 End-to-End Customer Churn Prediction
- Built an ML pipeline (Logistic Regression, RF, XGBoost, Voting Classifier) → ROC-AUC: 0.87
- Applied KMeans & HDBSCAN clustering with UMAP to segment customers into actionable personas
- Used SHAP explainability to reveal key churn drivers (tenure, contract type, fibre optic service)
- Deployed interactive Streamlit App for business users
- Containerised workflow with Docker, reducing setup time by >80% and ensuring reproducibility
- Tracked experiments, metrics, and models with MLflow, improving transparency and versioning across the pipeline
- Designed an A/B testing simulator with Chi-Square tests to measure the impact of retention strategies
- Big Data Platforms (PySpark, AWS, Databricks)
- Deep Reinforcement Learning
