About Walid
AI Automation Developer | n8n, AI Agents & RAG Systems
Peshawar, Pakistan - 1:56 am local time
I build AI agents, n8n automations, RAG systems, and full-stack AI applications using React, Next.js, Node.js, and Python for startups and agencies.
Whether you need to automate lead handling, connect business tools through APIs, build an internal AI assistant, improve an existing RAG pipeline, or turn an AI idea into a working MVP, I focus on reliable architecture, clear error handling, and maintainable delivery.
What I can build
• AI agents and LLM workflows using OpenAI, Claude, Gemini, LangChain, and LangGraph
• RAG applications with Pinecone, pgvector, or Chroma for document search and AI assistants
• n8n workflows with APIs, webhooks, OAuth, retries, error handling, and human approval steps
• CRM and business automation for GoHighLevel, HubSpot, Salesforce, and third-party tools
• Full-stack AI applications using React, Next.js, Node.js/Express, and Python/FastAPI—including dashboards, chat interfaces, APIs, integrations, and backend services.
• Database and deployment setups using PostgreSQL, MongoDB, Redis, Docker, AWS, GCP, or Vercel
How I approach projects
• Start by understanding the workflow, users, integrations, and success criteria
• Build a practical solution with clean, maintainable code
• Add logging, error handling, retries, and monitoring where the workflow requires it
• Provide documentation and a Loom handover walkthrough
How I use AI in production codebases
I use AI to accelerate delivery without compromising your codebase’s architecture or maintainability. Before implementing changes, I review the relevant repository patterns, shared utilities, service layers, tests, and API contracts so new code fits the existing system.
My workflow is: understand first, plan second, implement third, verify fourth.
Review relevant files, existing patterns, and similar implementations before changing code
Reuse established services, utilities, validation, authentication, logging, and error-handling layers
Share a clear implementation plan before larger changes
Keep changes minimal, scoped, maintainable, and consistent with existing architecture
Run relevant tests, type checks, linting, and build validation before handover
Request approval before adding dependencies or changing authentication, deployment, payments, or production infrastructure
What you receive
A documented implementation designed for real business workflows
Clean, maintainable code with appropriate error handling and logging
Clear technical communication throughout the project
Loom walkthroughs and written handover documentation when needed
Relevant experience
I have 5+ years of backend and SaaS development experience, including API-driven applications, cloud storage, database optimization, automation workflows, and customer-support chatbot integrations. I use that backend foundation to build AI systems that are dependable, secure, and ready to evolve with your business.
If you have an automation bottleneck, an AI concept, or an existing workflow that needs improvement, send me the details. I’ll help you define a practical first milestone and implementation plan
