# Nishanthan Janarthanarajah (Nishy): founder of Agent Studio and Flows

> Founder of Agent Studio and Flows · Associate Technical Lead at Eight25Media · Colombo, Sri Lanka

Independent AI engineer building AI agents, RAG assistants and workflow automation for businesses in Sri Lanka and worldwide, and creator of two live AI products, Flows and Agent Studio.

**Availability:** Accepting new client projects: custom AI agents, workflow automation, RAG assistants, AI features and MCP servers. Remote-first from Colombo, Sri Lanka, with overlap for US, UK, European and Asia-Pacific hours. Replies within a day.

Full Stack Developer and Engineering Lead with 7+ years architecting and delivering scalable, high-performance solutions across JavaScript/TypeScript, Next.js, React, Node.js, headless CMS, and cloud platforms. I lead cross-functional engineering teams end-to-end, from architecture through production, while aligning technical execution with business and marketing goals. I've scaled engineering teams from 6 to 31 engineers, directed enterprise B2B platform delivery, and built trusted client relationships, with deep experience in Next.js/Contentful/Vercel architecture, technical SEO, caching and performance engineering, CI/CD pipelines, and AWS. I'm increasingly focused on applied Generative AI and LLM application engineering: designing production Retrieval-Augmented Generation (RAG) systems on Azure AI Foundry and Azure OpenAI with Pinecone vector search and role-aware prompt guardrails, and building Model Context Protocol (MCP) servers that let AI agents drive design-to-code generation and headless CMS content automation. If you want to put AI agents to work in your business — agentic workflows, RAG assistants over your own data, MCP servers, or AI features inside your product — I'd love to talk about what you're building.
