• TypeScript
• Component-driven UI design
• Performance-focused frontend engineering

Backend

• Python (FastAPI / Flask / Django-style architectures)
• REST & event-driven APIs
• Asynchronous and concurrent systems

AI / ML & Data

• Model inference pipelines
• ML model integration (not just notebooks)
• Data-heavy, real-time or near-real-time systems
• Exposure to tools such as PyTorch, TensorFlow, or similar (hands-on or integration-level)
