At Primathon Technology, I architect the backend for Xneeti, an Amazon Ads and SP-API analytics platform that tracks sales, ROAS, TACoS, and campaign performance. I built RabbitMQ scheduling and real-time AWS SQS/EventBridge pipelines to keep PostgreSQL analytics data current for dashboards and AI queries.
I also built a FastAPI, LangChain, and OpenAI chatbot that translates plain-English questions into SQL, reducing ad-hoc data requests by about 40%. Its pgvector RAG layer reached roughly 90% query accuracy on a 50+ question benchmark, while an AI agent automated campaign actions and lifted ROAS by about 15%.
Previously, I delivered WebRTC live streaming for 1M+ daily active users at HKB Development and launched full-stack React, Node.js, and MongoDB applications at Immanent Solutions. I enjoy building scalable microservices, real-time systems, and reliable APIs with practical guardrails and measurable performance gains.
