What I Do
Services I Offer
From data strategy to production-ready AI — here's how I can help your business grow.
Data Analytics & Business Intelligence
Turn your raw data into revenue-driving decisions. I design end-to-end BI pipelines, interactive dashboards, and automated reporting systems that give your team real-time visibility — without waiting on engineering.
AI/ML Model Development
From OCR systems to NLP pipelines, I build production-ready AI models tailored to your business problem. You get a working model, clean training data, and evaluation metrics — not just a Jupyter notebook.
Backend API Development
Scalable Django REST APIs with JWT authentication, Swagger documentation, and production-grade architecture. Whether it's a fintech app or a data platform, I build backends that handle real-world load.
Data Warehouse Design & Migration
Stuck with slow, expensive legacy data infrastructure? I migrate Hive/EMR systems to modern cloud warehouses, optimize query performance, and set up AI-ready data layers — typically cutting costs by 30–50%.
