Building mobile applications and exploring intelligent systems

About Me

I’m a Flutter Developer with practical experience building user-focused mobile applications and integrating APIs, responsive UI systems, local databases, and scalable application architectures. Over time, I’ve worked on multiple real-world and personal projects that strengthened my understanding of performance optimization, backend connectivity, state management, and maintainable software design. Recently, I’ve been focusing on expanding my expertise into Data Science and AI by developing projects involving machine learning pipelines, predictive modeling, financial affordability analysis, regression-based forecasting systems, and FastAPI-powered backend services. My current work includes experimenting with Dockerized ML workflows, feature engineering, preprocessing pipelines, and interactive Flutter interfaces connected to intelligent backend systems. I’m particularly interested in the intersection of mobile engineering, AI, and data-driven applications, where modern software systems can deliver more personalized, scalable, and impactful user experiences.

1
AI-powered Vehicle Affordability and Financial Risk Analysis

AI-powered Vehicle Affordability and Financial Risk Analysis

Currently developing an AI-powered Vehicle Affordability and Financial Risk Analysis platform using Machine Learning, FastAPI, Docker, and Flutter. The project includes three ML models: Vehicle Price Prediction (Regression), Potential Savings Prediction based on spending habits (Regression), and EMI Risk Prediction (Classification). Built preprocessing pipelines with feature engineering, encoding, scaling, missing value handling, and model evaluation using Scikit-learn. Planning to containerize the backend using Docker, expose ML prediction endpoints through FastAPI, and integrate the system into a Flutter application with interactive UI and 3D vehicle visualization.

Deep Focus

Deep Focus

Currently developing a cross-platform wellbeing and productivity application called Deep Focus using Flutter to help users improve concentration and reduce digital distractions. Implemented features such as focus sessions, smart app blocking, productivity insights, mood tracking, multilingual support, weather-based suggestions using Weather API, maps integration, local database management, and Android Method Channel integration. The application follows a scalable MVVM-inspired architecture using Riverpod, reusable widgets, responsive UI design, and localization support. Planned features include biometric authentication, AI-powered suggestions, notification voice models and advanced deep focus modes.
