Harshal Belorkar

I’m an early-career data science and analytics professional with a background in Electrical Engineering (B.Tech) and Electronics & Telecommunication (Diploma). I build with a problem-solving mindset and a strong “data-driven decision-making” focus.

In my Data Science Intern role at InternsVeda, I developed a Time Series Sales Forecasting model in Python that achieved 92% prediction accuracy. I used SQL for data extraction and Power BI to create interactive dashboards, while cleaning and preprocessing data in Pandas and NumPy to support accurate modeling.

I’ve translated analytics into production-minded projects. For a Hospital Patient Management System, I designed a relational PostgreSQL architecture that improved query retrieval speeds by 25% and enforced 100% data referential integrity using SQL constraints and triggers. In my Sales Dashboard and Sales Forecasting projects, I re-engineered data into a Star Schema for a 30% faster load time and used ARIMA/Prophet models to reach MAPE under 8%, with Power BI visuals that improved resource allocation decisions.

I enjoy collaborating with teams in virtual sessions and refining solutions in an Agile, consulting-style environment. I’m excited to bring forecasting, BI, and SQL engineering to roles where business impact and zero-defect delivery matter.
