About Me

I’m a Senior Software Developer passionate about designing scalable backend and AI-driven systems. I specialize in building data pipelines, LLM-integrated analytics, and cloud-native automation using AWS, Python, and modern MLOps frameworks. My work at Zenoti and previous roles has focused on real-time dashboards, AI-based customer insights, and production-ready data architectures.

With hands-on experience across LLMs (Anthropic, OpenAI), AWS (Athena, Lambda, Batch, API Gateway), and data ecosystems (DynamoDB, SQL, PySpark), I aim to bridge applied AI research with real-world engineering.
