Fullstack Developer

 Develop and maintain scalable full stack applications using: Node.js, TypeScript, Next.js (App Router) and Hono.

Implement the conversational experience — chat UI, streaming responses and tool/function calling — using the Vercel AI

SDK against Azure OpenAI / Azure AI Foundry models.

Design and build the Retrieval-Augmented Generation (RAG) layer: embeddings, semantic search and a vector store, so

answers are grounded in Apex’s data.

Develop backend services — REST and streaming APIs, serverless functions — and the secure connectors to the source

systems the chat queries.

Implement authentication and authorization (OAuth 2.0, JWT, NextAuth) with data-access controls, so users only query

data they are permitted to see.

Add evaluation, guardrails, observability and token/cost management to keep responses accurate, safe and economical.

6+ years full-stack (2+ hands-on with LLM apps).
