WMS AI Copilot overview

🛠️ Tech Stack

  • Groq Cloud (Llama 3.x)
  • Vercel AI SDK
  • TypeScript
  • Next.js (App Router)
  • Express
  • Supabase (PostgreSQL)
  • Tailwind CSS
  • shadcn/ui
  • TanStack Query & Table
  • next-intl
  • Jest
  • npm Workspaces

📖 Overview

Architected and built a full-stack, production-shaped monorepo for a real-time AI copilot designed for modern warehouse management. The project was built for my portfolio instead of a formal job position. The platform enables warehouse admins to perform natural-language queries for stock levels, top sellers, and reorder alerts, returning token-by-token streaming answers or sortable data grids. Engineered a live operational dashboard alongside a tool-calling AI agent, prioritizing data grounding, tight execution boundaries, and seamless internationalization.

🚀 Key Achievements

  • Engineered Real-Time Streaming & Tool-Calling Agent: Integrated Vercel AI SDK and Groq Cloud (Llama 3.x) to deliver low-latency, token-by-token streaming responses with deterministic database tool selection.
  • Designed Adaptive Visualization Pipeline: Developed an intelligent frontend engine that dynamically renders plain text, or TanStack sortable tables based on the schema of the query result.
  • Built Full Operational Split-View Dashboard: Designed a responsive Next.js App Router workspace featuring a resizable split view for real-time inventory, product, and order history tracking.
  • Established Security & Trust Boundaries: Enforced a secure LLM access model by restricting the AI to curated, strictly typed DB access tools rather than raw query execution.
  • Implemented End-to-End Internationalization: Architected the application from the ground up with next-intl to support fully bilingual (English/Spanish) conversational and UI flows.
  • Maintained High Monorepo Code Quality: Structured the project as an npm workspaces monorepo with strict TypeScript typing across API, frontend, and AI tool definitions, backed by Jest test coverage.

AI-assisted development

Besides my AI-related projects, I spent the last 2 years working everyday with AI agents (Claude Code, GPT, Cursor, Antigravity) scaffolding solutions in no time then iterating over those solutions by receiving feedback and working over the feedback. Developing quality solutions faster.
