Still paying for tools that don't talk to each other? I build n8n automation workflows and API integrations that fix that — cleanly, on infrastructure you own and control. No vendor lock-in, no recurring SaaS fees you can't escape. Most automation freelancers hand you a Zapier flow and disappear. I deploy self-hosted n8n on your VPS or cloud (Docker, Linux), wire it to your existing stack via REST APIs and webhooks, and leave you with code and infrastructure you fully own. That means no subscription surprises and no single point of failure you can't debug yourself. What I build for SMBs and SaaS startups: 🔗 API & webhook integrations between any two platforms ⚙️ Automated workflows that replace manual ops work 🖥️ Self-hosted n8n setups on VPS or cloud (Docker, Linux) 🤖 AI agents and RAG chatbots connected to your live data 📊 CRM, lead gen, and data pipeline automations 🔍 Web scraping and data enrichment pipelines ✅ 100% Job Success Score across 28 completed projects on Upwork ✅ Top Rated freelancer — $57K+ earned, 11 active client engagements ✅ Clients include SaaS startups and SMBs across e-commerce, logistics, real estate, and recruitment ✅ Notion Service Specialist certified Send me a message describing what you're trying to automate. I'll reply within a few hours with a clear scope and whether I'm the right fit.

I’m a backend software engineer specializing in Python, FastAPI, and API integrations, with strong experience building scalable, secure backend systems. I design and implement production-grade APIs with JWT authentication, RBAC, and rate limiting, and deploy services on AWS using Docker and CI/CD pipelines. I’m comfortable owning systems end-to-end, from architecture through deployment and monitoring. I also work with AI-powered systems, including RAG pipelines and custom agent-style chatbots that interact with real data and APIs. My focus is on reliability, structured outputs, and practical automation — not demo prototypes. Core skills: -Backend development (Python, FastAPI) -API & SaaS integrations -Secure, scalable system design -AI systems (RAG, agent tools) -AWS deployment & CI/CD If you need a backend engineer who builds real, production-ready systems, I can help.

I help businesses save time by building practical AI automation systems, n8n workflows, AI agents, and CRM automations that connect the tools they already use. Most businesses do not need a complex AI platform. They need simple systems that can handle leads, follow-ups, customer replies, CRM updates, Google Sheets, WhatsApp messages, emails, document search, and reporting without manual work. That is what I build. I work with n8n, OpenAI, Claude, GoHighLevel, WhatsApp, Google Sheets, Airtable, Notion, CRMs, webhooks, REST APIs, FastAPI, Python, PostgreSQL, Docker, and cloud/VPS deployments. What I can help with: AI Automation & n8n Workflows I build n8n automation workflows for lead capture, lead qualification, CRM updates, email follow-ups, Google Sheets automation, Airtable/Notion workflows, reporting, onboarding, and internal business processes. AI Agents for Business Operations I build AI agents that can understand business tasks, use tools, update records, summarize data, send messages, qualify leads, route customer requests, and support daily operations. GoHighLevel & CRM Automation I can set up GoHighLevel workflows, pipelines, appointment booking, missed-call text-back, lead routing, SMS/email automation, review requests, webhooks, API integrations, and reusable client snapshots. WhatsApp, Email & Customer Support Automation I build AI-assisted WhatsApp bots, email automation, support workflows, reply drafting systems, customer triage, escalation logic, and human-approval workflows so your team can respond faster. RAG Knowledge Base & Document AI I build private knowledge base assistants using OpenAI, Claude, Gemini, RAG, vector databases, Google Drive, PDFs, Docs, Sheets, Pinecone, pgvector, LangChain, and LangGraph so teams can ask questions and get answers from their own documents. Voice AI & Appointment Booking Systems I can help with AI voice agents using tools like Vapi, Retell, Bland AI, Twilio, ElevenLabs, and GoHighLevel for inbound calls, after-hours answering, lead qualification, appointment booking, and call follow-up workflows. Custom AI Apps & Backend Integrations When no-code tools are not enough, I can build custom AI backends using Python, FastAPI, APIs, webhooks, PostgreSQL, Supabase, Docker, and cloud deployment. Recent work includes AI automation systems, n8n workflows, OpenAI/Claude integrations, GoHighLevel pipelines, RAG assistants, OpenClaw/Hermes agent setups, MCP server integrations, chatbot systems, and private AI web apps. My focus is simple: understand the business workflow first, build a clean automation, test it with real examples, document it clearly, and make sure your team can manage it after handoff. If you want to automate leads, CRM, WhatsApp, email, documents, customer support, or internal workflows, send me the process you want to improve and I’ll suggest the cleanest setup.

I help e-commerce stores fix the parts of the business that still run manually; sending receipts, following up with customers, tracking orders, using automation built in n8n. I'm Hussein. I build e-commerce automation for Shopify and WooCommerce stores, and automation for service businesses that lose jobs to slow follow-up. If something in your store or business currently takes a person time to do by hand, and it happens the same way every time — I can probably build a system that does it for you. What I build: 🎯 E-commerce automation for Shopify and WooCommerce: order receipts, abandoned cart follow-up, review requests, refund handling. 🎯 WhatsApp automation for customer support and order tracking; including the Meta Business verification needed to get approved and running properly. 🎯 Automated responses to customer messages on SMS, email, WhatsApp, Facebook, and Instagram, so replies go out fast without someone manually typing every one. 🎯 Connecting the tools you already use like your store, your CRM, your spreadsheets so information moves between them without anyone copying and pasting. 🎯 Automating inbox management: sorting, labelling, and replying to routine emails automatically FEEDBACK "We were drowning in unqualified leads from Google Local Ads, every message needed manual follow-up and it was eating our team's time. Hussein built a full intake automation using n8n, Twilio, Sheets and OpenAI that handles lead qualification on its own. We haven't manually processed a single intake lead since it went live." — Sam H. ⭐⭐⭐⭐⭐ Results from real projects: 📍 A Shopify store was manually creating and sending order receipts. I built an n8n automation that does it instead, 294 orders handled automatically in the first month, saving 48.6 hours of manual work. 📍 A service business was missing bookings because leads weren't followed up fast enough. After automating the response with n8n, bookings went up 65%. 📍 A business was spending 40+ hours a week manually sorting and replying to emails. An n8n customer support automation now handles that instead. 📍 A broken system that three other developers couldn't fix, I found and resolved the issue within 24 hours. All these results can be found in my portfolio section How a project works: We talk about what's manual. You tell me what's eating your time; order handling, follow-ups, customer messages, whatever it is. I map it out and show you exactly where the automation would fit, before any work starts. I build it. Using suitable automation platform n8n, Make or Zapier, tested against your real order or message volume, not just a demo version. You get a working system. Live, explained to you in a walkthrough video, with 14 days of support if anything needs adjusting. Who this is for: 📍 Shopify, WooCommerce or E-commerce store owners doing receipts, cart recovery, or order tracking by hand. 📍 Businesses wanting WhatsApp automation for support or order tracking, but stuck on the Meta Business verification step. 📍 Service businesses; roofing, real estate, contracting, cleaning losing jobs because follow-up is too slow. 📍 Not seeing your situation here? Tell me what you're doing manually, let's get your business working on autopilot.
