What I'm looking for

I’m seeking a Data Analyst, Data Scientist, or Machine Learning Engineer role.

At Dream Ahead Tech Pvt. Ltd, I developed an end-to-end pipeline for Excel and PDF retrieval, OCR, and Gemini-based skill extraction. I also automated web scraping of 500+ job records and stored the extracted data in PostgreSQL.

During my internship at Skillfied Mentor, I performed exploratory data analysis, preprocessing, and feature engineering on real-world datasets. I built and evaluated skill-matching machine learning models using Scikit-learn.

For my gold price prediction project, I built a hybrid TCN-LSTM model and achieved 95.17% accuracy through time-series preprocessing and model optimization.

I also developed credit default prediction models using Logistic Regression and Random Forest, and conducted exploratory analysis, feature engineering, and performance evaluation. I’m completing an M.Sc. in Mathematics with Data Science at IILM University.
