Github

Open Source Developer

Aug 2018 – Present · 7 yrs 10 mos

As an open-source developer on GitHub (github.com/sayantanr), I did a variety of projects that showcase my skills in Python, SQL, and system automation, reflecting my 3 years of experience as a service desk engineer at Cognizant, where I did L2/L3 support for clients like Nike and Cargill. I did a Streamlit-based exploratory data analysis (EDA) application, which I built to help users visualize and analyze data easily through interactive web interfaces, using Python libraries like Matplotlib and Pandas. I also did a custom Linux operating system, where I customized a lightweight Linux distribution for specific use cases like development environments, including kernel configuration and package management. Additionally, I did an inventory management system using Python and SQL, which I designed to streamline retail operations by automating stock tracking and integrating with ServiceNow for incident management. These projects, shared openly on GitHub, show my commitment to creating practical tools that others can use and contribute to.
I did several other impactful projects that highlight my versatility. For instance, I did a sentiment analysis tool using PyTorch and TensorFlow, enabling users to analyze text for emotions, which I made adaptable for custom datasets like customer reviews. I also did a transliteration project, converting old Sanskrit texts to Bengali using Python and NLP techniques, contributing to cultural preservation. I did a railway reservation system and a resume maker website, both using Python and web technologies to address real-world needs. Each project I did includes clear documentation on GitHub, encouraging community contributions and feedback. Through these efforts, I did my part to make technology accessible and useful, aligning with my professional experience in retail IT and my passion for open-source development.
