Abaid Ullah

I specialize in transforming standard applications into production-ready, autonomous AI platforms, complex multi-agent systems, and highly scalable web and mobile software.
From designing resilient Retrieval-Augmented Generation (RAG) pipelines to developing secure full-stack software,
I build enterprise-grade, data-driven solutions optimized for the modern web.
Core Capabilities & Tech Stack
GenAI & Agentic Frameworks: Architecting autonomous multi-agent orchestration, complex workflows, and intelligent workflows using LangGraph, LangChain, and n8n automation.
Advanced AI Infrastructure: Engineering enterprise RAG pipelines, production-grade vector database implementation (Pinecone, pgvector), rigorous LLM evaluations, and robust hallucination mitigation protocols.
Full-Stack Development: Scalable web platforms engineered with React, Next.js, Node.js (Express, Nest.js), and interactive cross-platform mobile app development with React Native.
Cloud Operations & Architecture: Secure system administration via AWS (EC2, ECS, S3, Auto Scaling), database management (PostgreSQL, MongoDB, Prisma), containerization with Docker, and automated GitHub Actions CI/CD
