What I'm looking for

I seek a role building scalable backend systems and AI/ML products where I can apply software architecture and model optimization skills, collaborate with a strong engineering team, and grow in production ML deployments.

I am a creative software engineer who builds robust backend systems and intelligent applications, turning complex problems into clean, efficient Python code. I specialize in designing scalable REST APIs, containerizing services with Docker, and developing end-to-end AI/ML pipelines that deliver high-impact, data-driven products.

My projects include an AI-powered deck builder using a RAG pipeline with ChromaDB and LLMs, and a thesis on neural network pruning that achieved 40%-60% parameter reduction with minimal accuracy loss. I bring strong software architecture skills, practical experience with PyTorch and FastAPI, and a collaborative, results-oriented approach.
