Question 2

Multi-agent LLM systems (LangChain, LangGraph, RAG), document AI combining OCR, object detection and LLMs, real-time computer vision and edge AI, and building complete AI SaaS products from idea to paying users.

Question 3

How can we work together?

Accepted Answer

Three ways: a direct project, where I design and build an AI product or feature; a startup collaboration, where we build a new AI product together; or AI leadership, where I lead your AI strategy, architecture and team as a fractional Head of AI or longer term.

Question 4

Are you open to startup collaborations?

Accepted Answer

Yes. If you're a founder with an idea that needs serious AI, I'm happy to talk about building it together. I've founded and grown my own AI product, so I think about users and business results, not just the model.

Question 5

Do you work with companies outside Sri Lanka?

Accepted Answer

Yes — most of my clients are in the US and Europe. I work remotely from Sri Lanka with good time-zone overlap for both regions, and I also work with Sri Lankan companies and founders.

Question 6

Can you lead an AI team in Sri Lanka?

Accepted Answer

Yes. I lead a team at Calexa Innovations that builds AI for clients, and I can lead or build out an AI engineering team in Sri Lanka for local or overseas companies.
