About

I’m Tuhin — a Chemical engineer turned data analyst, currently pursuing PGDM (Big Data Analytics) at Goa Institute of Management, Goa. I build business intelligence and analytics solutions that turn messy data into clear, actionable decisions people actually use — combining engineering rigor with product-minded execution to deliver dashboards, KPI frameworks, and performance-tuned reporting. At Celebal Technologies : • Delivered a 54-page Power BI P&L built with 300+ DAX measures and advanced time intelligence, improving report usability and reducing query load times by ~40%. • Led an internal project at Celebal to define 150+ KPIs and translate 200+ SQL/DAX queries into reproducible documentation — improving performance and long-term maintainability. • Developed sustainability simulations for hydrogen production during an ONGC R&D project, blending engineering domain knowledge with analytics to solve practical problems. 📌 Skills • BI & visualization — Power BI, Power Query, advanced DAX, Excel (modeling → dashboards → storytelling). • Data fundamentals — SQL, Python, data modeling, ETL best practices. • Operator mindset — KPI design, performance tuning, reproducible documentation, and a bias for execution. • Communication — translate technical complexity into concise, stakeholder-ready insights. 🎓 Education & skills I’m pursuing PGDM — Big Data Analytics at Goa Institute of Management, Goa, and hold a B.E. in Chemical Engineering from Jadavpur University. My professional skill set includes product lifecycle management, UX/UI design, data analytics, and AI/ML applications. If you’re building dashboards, KPI systems, or analytics products that need both domain depth and clear storytelling, let’s connect — I enjoy turning data into decisions that drive action.
