Backend&AISystemsEngineer
I build high-concurrency backend systems (Go/Golang, FastAPI) and production-ready AI architectures — multi-agent systems using RAG, tool-calling, and scalable MLOps to deliver intelligent products.

/ About
Intelligence first. Then the product around it.
I'm a Backend & AI Systems Engineer from Sri Lanka with a foundational background in Combined Mathematics and Physics. My work centers on building high-concurrency backend architectures (primarily in Go/Golang and Python with FastAPI) that reliably serve intelligent applications at scale.
I design and implement multi-agent AI systems that leverage Retrieval-Augmented Generation (RAG), tool-calling, and orchestrated agent workflows. My focus is on production-ready backend systems, observability, and engineering patterns that make AI systems robust and maintainable in real-world settings.
I'm the creator of Amptudix, where we apply these principles to music intelligence. By owning the full engineering cycle — from data pipelines to backend services to deployment — I ensure that intelligence is embedded into the product architecture.
