What I'm looking for

I’m looking to lead architecture for cloud-native AI backend platforms—LLM/RAG pipelines, distributed inference, and observability—delivering reliable, low-latency, multi-tenant systems in production.

I’m a Senior AI Software Engineer with 6+ years of experience building scalable AI platforms, distributed systems, and cloud-native applications across enterprise SaaS and AI infrastructure environments. I specialize in AI-powered backend platforms—LLM integrations, RAG pipelines, semantic search systems, and automation workflows—backed by low-latency, scalable, multi-tenant delivery.

In my recent role, I owned key backend architecture decisions and delivered distributed AI services on AWS and Azure, including OpenAI API agent workflows, RAG with vector databases and embedding pipelines, and event-driven inference orchestration using Kafka, Redis, BullMQ, and Celery. I improved conversational response reliability by 32%, reduced backend processing latency by 30%, and scaled to 65K+ daily conversations through modernization and Terraform-based automation.
