What I'm looking for

I am seeking remote roles where I can lead full-stack and AI integrations, own architecture decisions, and deliver scalable, cost-effective production systems with strong team collaboration.

I am a Senior Full-Stack Developer with over 8 years building scalable web applications and AI-driven products, comfortable owning technical decisions from design through production. I have shipped systems integrating modern language models and retrieval-based architectures, and I deploy and maintain cloud-native systems using CI/CD, Docker and Kubernetes.

I excel at collaborating with product, design and engineering teams in remote environments to deliver reliable, user-focused solutions. My recent work includes architecting an AI bid-matching platform, building RAG-based chat copilots, and leading model and vector-store evaluations to drive cost-effective production deployments.
