I design and ship backend systems that hold up in production — REST APIs, authentication layers, multi-tenant architectures, and real-time features — with an equal focus on clean, maintainable frontend delivery when the project calls for it.

Backend & APIs Node.js and Express.js for building REST APIs that handle real traffic — JWT/OAuth authentication, WebSockets for real-time features, and background jobs for anything that shouldn't block a request.

Databases MongoDB and PostgreSQL, from schema design through query optimization — picking the right store for the data shape instead of defaulting to one.

Frontend React.js and Next.js with TypeScript, Redux Toolkit for state, Tailwind CSS and Shadcn UI for interfaces that are fast to build and don't look templated.

Android Kotlin with MVVM architecture and Firebase — structuring apps so business logic stays testable and UI stays reactive, with responsive layouts across devices.

Data & Machine Learning Python, Pandas, and NumPy for data analysis and preprocessing, applied to building and evaluating ML models.

Infra & Tooling Docker for consistent environments, AWS for deployment, Redis for caching, CI/CD pipelines, and Git/GitHub for version control.

AI Integration Wiring LLMs (Gemini, Claude) into real product features — conversational interfaces, voice assistants, and generation pipelines that go into production, not just a demo.
