Growth shouldn't require more people. Reliable Automation powered by Claude, AI Agent Development, and n8n eliminates repetitive work, reduces operational costs, and gives your business the Automation it needs to scale with confidence. Manual work, disconnected systems, and unreliable Automation quietly reduce productivity, increase costs, and slow growth. Whether you're dealing with broken API Integration, rising Claude API costs, repetitive processes, or unreliable CRM Automation, the challenge is rarely Artificial Intelligence. The challenge is building Automation that works consistently in production. If any of these challenges sound familiar, your business is ready for better Automation. • Hours spent moving data between systems because API Integration isn't reliable. • CRM Automation that creates duplicate records or misses critical updates. • Marketing Automation and Email Automation that stop after a token expires or an API changes. • Claude workflows that work in testing but fail in production. • Rising Claude API and OpenAI API costs caused by inefficient AI Agent Development. • Teams spending more time fixing Automation than benefiting from Automation. • Workflow Automation that breaks as your business grows. • Lead Management Automation that fails to update your CRM or route new opportunities. • Lead Generation that still depends on manual work instead of intelligent Automation. Reliable Automation should eliminate these problems, not create new ones. Production-ready AI Agent Development transforms Claude into a reliable business system instead of another chatbot. Claude should automate repetitive work, execute business processes, support decision making, and connect every critical application through secure API Integration. Every AI Agent Development project should strengthen Automation, improve Workflow Automation, and reduce operational costs instead of creating more complexity. Reliable Automation connects Claude, n8n, Make com, Python, API Integration, Zapier, Airtable, and HighLevel into one connected ecosystem. Whether your business needs CRM Automation, Marketing Automation, Email Automation, Lead Management Automation, or Workflow Automation, every Automated Workflow should reduce manual work, improve Lead Generation, and continue creating value as your business grows. Artificial Intelligence delivers measurable results when Automation is built around business outcomes instead of demonstrations. Claude, OpenAI API, Python, API Integration, AI Agent Development, n8n, and Make com work together to build Automation that scales, improves CRM Automation, supports Marketing Automation, strengthens Email Automation, and keeps every Workflow Automation reliable. The outcome is simple. • Less manual work. • Lower operating costs. • Reliable Automation that scales with your business. • Smarter AI Agent Development powered by Claude. • Secure API Integration connecting every business system. • Production-ready n8n, Make com, Zapier, Airtable, and HighLevel workflows. • Better CRM Automation, Marketing Automation, Email Automation, Lead Management Automation, and Lead Generation. SEO PURPOSE If your business has outgrown manual processes and unreliable Automation, it's time to build Automation that continues creating value. Claude, AI Agent Development, n8n, API Integration, Make com, Python, Artificial Intelligence, CRM Automation, Workflow Automation, and Marketing Automation should help your business grow while your team spends less time managing repetitive work.

I build Laravel web applications, n8n automations, custom websites development and APIs that connect the tools your business already runs, so CRM updates, lead follow-up, reporting and data pipelines happen without anyone touching them. Custom web applications, websites, automation backends, Laravel SaaS platforms, database systems, custom API systems, AI agent development and automated workflows that eliminate manual work: that is what I build, and I build it to last. Manual work, disconnected tools and stalled projects cost you time and money. I build the systems that make them disappear, permanently. The proof: 30 contracts delivered, 462 hours logged, a 100% Job Success Score, and every rated contract closed at 5.0. I'm Ezra, a full stack developer and automation engineer building web systems professionally since 2016. Clients hire me when manual work is eating their week, when two systems refuse to talk to each other, or when a build has stalled and needs someone who actually finishes. RECENT WINS 🔹 Recruitment job board (Australia). Laravel platform that scrapes council and company career pages on a schedule, de-duplicates listings, stores them in MySQL and emails alerts on new roles.

My longest-running contract at 16 months with a 5.0 rating, a custom API bridge syncing form submissions into Salesmate and MySQL with no re-entry. 🔹 n8n reporting workflows.

WHAT I DO 💻 Laravel & Full Stack Web Development Laravel and PHP backends. React, Vue.js, Next.js and TypeScript frontends. MySQL and PostgreSQL schema design and query tuning. SaaS platforms and startup MVPs taken from zero to production. Stripe and Paystack payments, Linux servers, CI/CD and Cloudflare. ⚙️ Workflow Automation & AI n8n workflow development.

Anti-bot handling on JS-heavy sites. Data cleaning and normalisation. Scheduled CRON pipelines with monitoring and alerting. HOW I WORK 🔹 You get a scoped plan before I write code, so there are no surprise invoices. 🔹 Systems are built to run unattended. Error handling, logging and alerts are included, not billed as extras. 🔹 Issues get flagged early and documented, so you always know where your project stands. 🔹 Available for a one-off fix or as a long-term automation partner. 💬 "Ezra is an incredible asset to our organization. His work is top notch and he's able to help us do things we want but don't know how to pull off!" - Verified Upwork Client ⭐⭐⭐⭐⭐ BEST FIT FOR Founders, ops leads and agencies already running several tools that don't talk to each other, especially teams losing hours every week to copy-paste between a CRM, forms, spreadsheets and email. Not a fit for: WordPress theme tweaks, standalone design work, or same-day turnarounds on undefined scope. 📩 Tell me which process is costing you hours and I'll map out a fix. I reply within a few hours and offer a free 15-minute scope call.

Something in your business runs on manual work that should be running itself. I build the automation that fixes it, and I build it so it doesn't break next month. I'm Aliu, a Make com and Zapier automation specialist. I connect the tools you already use so data moves on its own, tasks stop slipping through the cracks, and a process keeps working whether or not someone remembers to run it. Top Rated on Upwork, 100% Job Success Score, every review 5 stars. WHAT I BUILD 1. Make com scenarios (Make, formerly Integromat) - multi-step workflows with routers, iterators, aggregators and proper error handling, for any process that repeats. 2. Zapier automations - multi-step Zaps, Paths, Filters, webhook triggers and app-to-app syncing for teams that live inside Zapier. 3. API and webhook integration - connecting tools that were never built to talk to each other: REST APIs, JSON mapping, OAuth, custom HTTP requests. 4. GoHighLevel integration - I've built and repaired a lot of GHL, so when your automation has to touch a GHL pipeline, calendar or workflow, that connection is handled properly instead of guessed at. 5. n8n workflows - for teams that want self-hosted control over their automation stack. 6. AI automation - Claude and ChatGPT built directly into your workflows for lead qualification, support triage, content generation and data processing. I regularly connect Airtable, HubSpot, Google Sheets, Google Workspace, Slack, Stripe, Shopify, QuickBooks, ClickUp, Notion, Calendly, Typeform, Twilio, Monday and GoHighLevel. WHO I WORK BEST WITH Agencies automating client delivery. E-commerce stores syncing orders, inventory and support. Coaches and course creators automating onboarding. Service businesses drowning in intake, scheduling and admin. Anyone running a manual process they've outgrown. MY PROCESS 1. Map it - I document how the process works today. Every step, every tool, every handoff. No guessing. 2. Architect it - I choose the right platform for the job. Sometimes that's Make com. Sometimes Zapier is simpler and cheaper. I'll tell you which and why. 3. Build it - with error handling, so it survives an API hiccup or a changed field instead of failing silently. 4. Hand it off - with documentation, so you're not locked into needing me forever. COMMON QUESTIONS 1. Can you fix an automation someone else built? Yes. Troubleshooting broken Make com scenarios and Zaps is a large part of my work. I find the root cause first, then fix it, I don't rebuild from scratch unless rebuilding is genuinely cheaper. 2. Make com or Zapier - which should I use? Zapier is faster to set up and better for simple, linear workflows. Make com handles complex logic, large data volumes and heavy API work at a lower operating cost. If you're unsure, describe your process and I'll tell you honestly which fits. 3. How long does a typical build take? A single workflow is usually 1–3 days. A full multi-workflow system is typically 1–2 weeks depending on how many tools are involved. 4. What happens if it breaks after handoff? Every build ships with error handling and documentation. If something breaks because a platform changed its API, message me, I don't disappear after delivery. Do you still take GoHighLevel work? Yes, especially when automation is part of the scope. GoHighlevel funnel, website, setup, GHL integrations, workflow repair and CRM syncing, usually alongside Make com or Zapier. LET'S START Send me your current process, the tools you're using, and what "running itself" would actually look like. I'll tell you honestly what it takes to build it right, and if automation isn't the answer, I'll say that too.
