I build AI and data solutions that turn business requirements into predictive, automation-ready applications.
What I'm looking for
At Microwe, I translate stakeholder needs into functional requirements and workflows across four client engagements and more than 20 system modules. I've produced 18 business and technical documents and supported UAT, test-case preparation, requirement validation, and change-request documentation.
I also contributed to a two-phase AI roadmap for a Swiss cosmetics e-commerce client, turning business requirements into practical AI capabilities and implementation priorities.
My project work spans predictive modeling, time-series forecasting, computer vision, recommendation systems, and MLOps. I built the SLASSCOM Provincial Winning Smart Fish Route Predictor, achieving 87.34% accuracy and 86.18% ROC-AUC with XGBoost and LSTM-based trend features.
I've also developed electricity-demand forecasting architecture, a CatBoost car-price model with a 0.912 test R-squared, an eye-gaze video-control system, AI product recommendations, and full-stack web applications. I bring hands-on experience with data digitization, cleaning, validation, feature engineering, LLM and RAG workflows, and translating real business problems into structured data-driven solutions.
