Rockstar🎓
Top SchoolNihal Chauhan is a data-focused systems engineer with 10 years of experience designing and operating large-scale data pipelines and ETL systems, now expanding into machine learning and statistical modeling. At TCS he translated complex business and compliance requirements into resilient architectures—most notably architecting near-real-time pipelines that processed over 2M daily transactions for the ZATCA e-Invoicing mandate with 99.9% data accuracy. He has a strong engineering foundation in optimizing pipeline performance (improving efficiency by ~30% and cutting runtimes by 20%) and hands-on experience building real-time analytics for network performance and government reporting. As a Code in Place section leader and active GitHub contributor, Nihal blends mentorship with practical CS fundamentals—implementing algorithms and data structures in C# and JavaScript while exploring CV, NLP, and deep learning. Based in Uttarakhand, he brings a rare combination of production-hardened infrastructure skills and a fast-moving curiosity for applying ML atop robust data platforms.
