Reinforcement Learning Specialist

Reinforcement Learning Specialist at xAI. Working on Model Context Protocol (MCP), Reinforcement Learning (RL) environments, and large language model (LLM) pre-training data.

02About

Craft, systems, shipping

I’m a full-stack developer in the JavaScript ecosystem and a Reinforcement Learning Specialist at xAI, grokmaxxing Grok since January 2026. I work on Model Context Protocol (MCP), Reinforcement Learning (RL) environments, and large language model (LLM) pre-training data. Before that I built product at Tradeics — a Saudi B2B trade platform — and spent five years at Bhagwad Krupa Softech shipping Next.js, React, Node.js and TypeScript systems end to end.

I work across the stack: React and Next.js on the client, Node.js APIs and Prisma/PostgreSQL on the server. Most of my work lives where the product is dense — roles, permissions, tables, and flows that have to stay fast.

Frontend

React, Next.js, Vue — interfaces that stay fast.

Backend

Node.js, Express, Prisma, PostgreSQL APIs.

AI systems

MCP, RL environments, LLM pre-training data.
