What I'm looking for

I seek roles building scalable backend and AI systems in collaborative, product-focused teams that value automation, cloud-native practices, and measurable impact.

I am a software developer with experience building scalable backend services, AI pipelines, and cloud-native solutions at scale, primarily using Node.js, MongoDB, AWS, and Azure. I have driven performance, reliability, and security improvements—delivering semantic search, embedding workflows, and CI/CD automation that reduced costs and accelerated releases.

I collaborate closely with product and data science teams, lead migrations to serverless and microservices architectures, and document complex AI implementations to enable rapid onboarding and knowledge transfer. I consistently meet aggressive timelines while maintaining zero security incidents and improving user engagement and retrieval accuracy across products.
