As a Junior Data Scientist, I worked on automating LLM (Retrieval-Augmented Generation) pipelines, streamlining the process of data retrieval and integration with generative models for enhanced outputs. I contributed to developing machine learning models, focusing on data preprocessing, feature engineering, and model optimization. Additionally, I implemented web scraping techniques to gather and process relevant data from various sources, enabling better training datasets for AI applications. This experience enhanced my skills in automation, NLP, and data engineering, while providing hands-on experience in building end-to-end data science solutions.

I spearheaded a RAG (Retrieval-Augmented Generation) project, integrating data retrieval systems with generative AI to deliver more accurate and context-rich responses. I guided the team through the development process, ensuring efficient integration of LLMs with external knowledge sources. In parallel, I mentored aspiring data scientists through Python classes, helping them develop core programming skills and practical knowledge in machine learning and data science. This role strengthened my leadership, technical expertise, and passion for teaching and mentoring.

As a Data Science Intern, I deepened my expertise through an intensive data science program, gaining hands-on experience in data analysis, machine learning, and AI applications. I focused on developing and deploying LLM-powered applications, leveraging tools like Python, NLP libraries, and cloud platforms. This internship honed my skills in data preprocessing, model building, and performance optimization, while also enhancing my ability to translate business needs into actionable insights and AI-driven solutions.

As a Lead Developer, I have mentored teams in web development and cloud-based solutions, focusing on both front-end and back-end technologies. I guided junior developers, conducted code reviews, and ensured adherence to best practices. My experience includes architecting scalable web applications and leveraging AWS services for deployment, storage, and security. I fostered a collaborative environment, enhancing the team’s skills in DevOps, CI/CD, and cloud infrastructure. This role strengthened my leadership and technical expertise, enabling the delivery of robust, cloud-native applications.

Organizing the Gurpurab event twice taught me invaluable lessons in leadership, teamwork, and time management. I honed my ability to coordinate diverse teams, ensuring seamless collaboration across tasks.Above all, it instilled a sense of community, responsibility, and cultural pride.

As a Junior Developer, I gained hands-on experience in building and designing web pages with a focus on functionality, responsiveness, and user experience. I worked with front-end technologies like HTML, CSS, and JavaScript, while integrating back-end frameworks such as Flask. This role strengthened my skills in debugging, version control (Git), and collaborating within a development team. It also sharpened my ability to meet deadlines and deliver scalable, user-centric solutions.
