Most founders find me after a React or Next.js build stalled: slow pages, brittle APIs, an AI feature that never shipped. I'm a full stack developer (React, Next.js, Node.js, TypeScript, Python) who does AI and API integration properly: RAG, agents, and OpenAI in production. ⭐ Top Rated · 💯 100% Job Success · ✅ 42 contracts, 421 hours on Upwork Nine years in web development: five as a software engineer at product companies (Signavio, Airlift), four freelance. Clients endorse me most often for quality of work , clear communication , and reliability . I build new products and I rescue existing ones. Roughly half my work is taking over a codebase someone else left behind and making it something your next developer will thank you for. ━━━━━━━━━━━━━━━━━━ 🛠️ WHAT I BUILD ✅ FULL-STACK DEVELOPMENT: the load-bearing stuff done right, so it doesn't break at 2am - React & Next.js App Router: Server Components, SSR/ISR/CSR, performance optimization - Node.js, NestJS, Python (FastAPI): REST and GraphQL API development and integration - Supabase & PostgreSQL: row-level security, realtime subscriptions, multi-tenancy - Auth & RBAC: Clerk, Supabase Auth, role-based access for B2B SaaS - Stripe API: subscriptions, metered billing, payment integration that doesn't leak revenue - TypeScript-strict throughout. DevOps on AWS, GCP, Vercel, Docker, GitHub Actions ✅ AI DEVELOPMENT & INTEGRATION: a working AI layer on software that already has users - RAG (Retrieval Augmented Generation) pipelines: Pinecone, pgvector, Chroma and other vector databases (legal search, healthcare KBs, enterprise Q&A) - AI chatbots that retrieve from your actual data instead of guessing at it - OpenAI API: GPT-4o, function calling, structured outputs, prompt engineering - LangChain & LangGraph (Python): AI agents and multi-agent workflows - AI automation (n8n, Make. com, Zapier, GoHighLevel): webhooks, CRM integrations, AI-triggered workflows ✅ API INTEGRATION & DEVELOPMENT - Third-party APIs, REST APIs, CRM systems, payment gateways, legacy service connections - 390+ hours on a single ongoing API integration and GoHighLevel customization contract ━━━━━━━━━━━━━━━━━━ 📦 RECENT BUILDS ✅ Entrepedia: PLR marketplace SaaS on Next.js with Stripe billing ✅ HealthdeskAI: AI CRM that turns leads into booked clients for fitness businesses ✅ RestoCommand: restaurant SaaS with AI demand forecasting that takes the guesswork out of inventory ✅ SellrGrid: multi-tenant marketplace built to onboard vendors without things breaking ✅ Smart Trainer LMS: learning platform with AI analytics and auto-generated certificates ✅ RAG crypto research platform: pulls clear answers out of scattered market data ━━━━━━━━━━━━━━━━━━ 🔄 HOW I WORK 1️⃣ Scope first. No code until we're aligned on exactly what we're building 2️⃣ Architecture doc before a single line is written 3️⃣ Weekly staging demos. Working software you can click, not status updates 4️⃣ Handoff-ready, TypeScript-strict code your next dev will thank me for 5️⃣ Only 2-3 projects at a time, so yours gets real attention ━━━━━━━━━━━━━━━━━━ 📩 Tell me what you're building: the idea, your timeline, your budget. I'll walk you through exactly how I'd approach it. I usually reply within a few hours.

I build AI agents, RAG chatbots, and automation systems that survive contact with real users, not demos that break the moment they leave the slide. That gap between "works in a demo" and "works in production" is why most of my clients come to me after something else fell apart. I'm Salah Eldin, an AI engineer with a 100% Job Success Score and Top Rated status on Upwork, 9 projects, 750+ hours, and systems that are still running for the people I built them for. What I do best: AI Agents & Automation, Custom agents and multi-agent systems (LangGraph, n8n) that take over repetitive work, with human-in-the-loop approval so the AI never acts on anything important without your sign-off. RAG Chatbots & Knowledge Systems, Assistants trained on your own documents that answer with citations instead of hallucinating, with strict data isolation so one user's data can never leak into another's. Voice AI & Integrations, Low-latency voice agents and clean API integrations with OpenAI, Claude, and Gemini. I work natively in Arabic and English, which matters for the MENA market. How I work: I obsess over the parts clients don't see, error handling, retries, the architecture that keeps your app responsive while the AI thinks. That's the difference between a system you trust and one you babysit. I'm also honest about fit, if I'm not the right person for your project, I'll tell you upfront. If you're adding AI to your product or replacing a slow manual process with something that runs on its own, send me a message with what you're working on. I'll give you my honest take before you commit to anything.
