I specialize in AI Integrations, voice AI systems, RAG pipelines, and AI Agent development and 𝐎𝐩𝐞𝐧𝐂𝐥𝐚𝐰, for startups and businesses ready to automate the work that's slowing them down. — WHAT I'VE SHIPPED IN PRODUCTION — ✅ Voice AI agent that replaced manual patient intake — zero staff needed for initial screening healthcare - (TopHealth AI), ✅ ML-core AI product — end-to-end, from model to production - (Akki.ai) ✅ End-to-end taxi booking platform live, scaled, real users - (TasleemTaxi), ✅ Published Jira Forge app on Atlassian Marketplace went through full review - (AgilePulse) ✅ Retail POS system deployed across UAE locations, handles real transactions daily - (Syspos) ✅ I build GoHighLevel (GHL) and n8n workflow automation for service businesses. Recent work: Nonstop Automation, where I own the GHL workflows, n8n pipelines, and AI automation connecting JobNimbus, Housecall Pro, AccuLynx, Jobber, and 10+ CRMs through custom API integrations. If your team is losing leads to manual follow-up or your CRMs aren't syncing cleanly, that's the exact problem I solve. — MY STACK — 📌 Voice AI: Vapi, ElevenLabs, Retell 📌 AI/ML: LangChain, LangGraph, RAG, OpenAI, OpenClaw, Anthropic/Claude Code 📌 Backend: FastAPI, Node.js, Python 📌 Automation: n8n, custom agentic orchestration and Twilio 📌 Frontend: Next.js, React 📌 Platforms: Jira Forge (Atlassian Marketplace) 📌AI Integration Architecture: connecting LLMs, Voice AI (Vapi/ElevenLabs), and automation. Most of my work right now is AI voice agents. Healthcare, fintech calls, legal intake, real estate, customer support, I've built for all of them. One of my favorites was a Vapi AI receptionist for a clinic chain in Florida. Patients call, it answers, books the appointment, done. No staff needed at 2am. I also built an outbound voice agent for a taxi company in Oman that takes booking calls in plain natural language. These handle real calls from real customers every day, which is a very different thing from a demo that works once in a sandbox. 𝐈 𝐝𝐨𝐧'𝐭 𝐰𝐚𝐢𝐭 𝐟𝐨𝐫 𝐲𝐨𝐮 𝐭𝐨 𝐡𝐚𝐧𝐝 𝐦𝐞 𝐚 𝐬𝐩𝐞𝐜 𝐬𝐡𝐞𝐞𝐭.

If you don't know MCP (Model Context Protocol), it's basically how you give AI agents real tools and a shared brain instead of stuffing everything into one giant prompt. I've built custom MCP servers and set up orchestration where multiple agents pass work between each other and actually finish tasks on their own. Some of this runs through n8n or Make, some is pure code. Depends what the project needs. — THE DIFFERENCE — 𝗘𝘃𝗲𝗿𝘆 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝘄𝗮𝗻𝘁𝘀 𝗔𝗜, 𝗯𝘂𝘁 𝗳𝗲𝘄 𝗸𝗻𝗼𝘄 𝘄𝗵𝗲𝗿𝗲 𝘁𝗼 𝘀𝘁𝗮𝗿𝘁.

Moreover, I've deep expertise in Anthropic Claude Implementations and Claude Integrations for multiple industries like healthcare, health-tech, Real estate, and financial sector. Most AI agent developers will leave you in dark when something stuck, I'll stay with you until it's done, and I never leave you with something you can't own and scale. 𝐃𝐞𝐦𝐨𝐬 𝐚𝐫𝐞 𝐞𝐚𝐬𝐲.

I'm a Google Certified web designer and developer with 15+ years building digital products that actually work, not just look good in a mockup. I've architected everything from B2B SaaS platforms and legal-tech ecosystems to full e-commerce builds and financial content portals, across Fortune 500 teams and lean SMB operations. My background sits at the intersection of UI/UX design and full-stack CMS development, which means I can own a project from the first Figma wireframe all the way through to a live, tested, production-ready site. Day-to-day, I work across Webflow, WordPress (Elementor, ACF), Wix Studio with Velo JS, Squarespace Fluid Engine, Framer, and Shopify OS 2.0; whichever CMS fits the project, not whichever one I happen to prefer. Design-side, everything starts in Figma, with Adobe Creative Cloud filling in where needed. For responsive web design I go well beyond breakpoint presets. I write custom CSS where the builder falls short and test across real devices, not just a resized browser window. On the automation side, I wire up Make, Zapier, GoHighLevel, and HubSpot to handle things like lead capture routing, client onboarding sequences, and CRM sync, so the site isn't just a brochure, it's doing actual business work in the background. I run projects in clearly scoped milestones so there are no surprise pivots at the finish line. The parts of web work that tend to go sideways, live site migrations, domain cutovers, staging-to-production pushes, cross-device layout inconsistencies. I treat those as planned steps, not last-minute scrambles. Before any milestone closes, I run Core Web Vitals checks, cross-browser QA, and a technical SEO pass so what goes live is actually solid. I communicate directly and keep you in the loop, not in the dark.
