Work experience

Data Science Intern

HexSoftwares • Part-time

Oct 2025 - Nov 2025 • 1 mo

Worked on end‑to‑end data science projects, from understanding business requirements and exploring raw datasets to delivering reports and dashboards. Performed data cleaning, feature engineering, and EDA using Python, SQL, and Excel, then trained and evaluated classification and forecasting models. Documented a clear, reproducible workflow so results could be improved and reused for future client‑style projects. Workflow: Understand business requirements → explore raw datasets → clean data & engineer features → perform EDA in Python → train & compare ML models → select best model using metrics → create reports & dashboards for decision‑makers.

Machine Learning Intern

CodeAlpha • Part-time

Jul 2025 - Sep 2025 • 2 mos

Worked on machine learning projects using algorithms such as Linear Regression, Logistic Regression, Random Forest, XGBoost, KNN, and K-Means clustering for classification, regression, and clustering tasks. Also applied train-test split, cross-validation, and model evaluation metrics to improve performance. Workflow: understand your problem → explore and clean the data (Complete Pre-process) → build and validate ML models → create clear dashboards/reports so you can take
