What I'm looking for

I’m looking to build scalable, maintainable backend systems for data-intensive AI applications—leading REST APIs, ingestion pipelines, and LLM integrations (RAG/workflows) on cloud-native platforms where strong system design and product impact matter.

I’m a Senior Software Engineer with 4+ years of experience designing scalable backend systems, distributed applications, and AI-powered solutions using Python, FastAPI, React, and AWS. I focus on high-performance REST APIs, data ingestion platforms, and cloud-native services that are production-ready and maintainable.

In my recent role, I contributed to RAG-based AI marketing analytics with FastAPI streaming APIs, built a scalable Dockerized data ingestion service on AWS, and improved backend responsiveness through better REST API design and asynchronous handling. I’ve also engineered LLM integrations and workflows (including RAG, LangChain, MCP, and Claude), and I’m excited to keep building system designs and AI applications that deliver real business impact.
