I have been working as a freelancer since last year, gaining practical experience across a wide range of technical and academic domains. During this time, I have completed multiple projects related to penetration testing, where I identified system vulnerabilities, performed security assessments, and provided recommendations to improve overall security. This experience helped me understand real-world cybersecurity challenges and ethical hacking practices. Alongside this, I have worked extensively in data analysis, handling both structured and unstructured datasets. I performed data cleaning, preprocessing, and applied statistical techniques to extract meaningful insights. I have used tools like Python (pandas, NumPy), SPSS for hypothesis testing and regression analysis, and KNIME for workflow-based analytics and data processing. My experience with machine learning has been another important part of my freelancing work. I have worked on multiple projects involving classification, regression, and predictive modeling. This includes tasks such as feature engineering, model selection, training, evaluation, and optimization. I have implemented machine learning algorithms using Python libraries such as scikit-learn and have also explored deep learning concepts when required.
