I design and build complete digital products end-to-end — mobile apps, web backends, and the AI/ML systems that make them intelligent. Selected work: • PharmaDelegate — Built an AI-powered pharmaceutical sales platform from scratch: a Flutter mobile app, a Django + PostgreSQL backend, and a machine-learning recommendation engine trained on real sales data that predicts what each pharmacy is most likely to buy, ranked by a confidence score. Integrated Odoo ERP for orders and invoicing. • Ozzy — Developed and shipped a social-commerce Flutter app with live payment integration, published to the Apple App Store and Google Play through an automated CI/CD pipeline (Codemagic). What I do: • Backend: Django REST APIs, PostgreSQL, Redis, Celery, Docker, JWT auth and role-based permissions. • Mobile & web: Flutter (BLoC/Riverpod, go_router), responsive web front-ends. • AI/ML: recommendation engines, LightGBM/XGBoost ensembles, feature engineering, SHAP explainability, and data-leakage prevention on real-world data; LLM integration (ChatGPT & Claude APIs); computer vision (image classification, OCR). Key achievements: shipped production apps to both app stores, built ML systems that turn messy real data into reliable, explainable predictions, and delivered clean, documented code that clients fully own.
