If your business is losing deals because of slow manual processes, disconnected tools, and delayed follow-ups, I fix that. I build smart, reliable AI automation systems that save time and increase revenue. In one recent project, I created an AI automation pipeline using AI automation Zapier that reduced lead response time from 6 hours to under 3 minutes for a growing SaaS company. Marcus ran a growing SaaS company losing deals because of slow, manual processes. Leads from different sources were manually copied into GoHighLevel, follow-ups were late, and there was zero visibility. I mapped his entire lead journey and built a powerful AI Workflow Automation using Zapier automation, AI automation Make, and n8n automation. The system captured every inbound lead via webhook, enriched the data with AI agent automation, pushed it into his CRM through seamless API integration, and triggered personalized email sequences. The entire AI agent workflow ran on autopilot with zero manual work. Within 48 hours, their lead response time dropped from 6 hours to under 3 minutes. His team stopped doing data entry and started closing more deals. Thatโ€™s the power of AI automation, AI agents, and intelligent workflow automation systems that work even when youโ€™re not watching. Iโ€™m Grace, a Zapier expert, n8n expert, and specialist in AI automation, workflow automation, and custom AI agent development. With deep experience in Zapier, Make, n8n, Airtable automation, GoHighLevel automation, and API integrations, I design end-to-end AI-powered automation solutions that help startups, agencies, and enterprises scale faster with fewer resources. WHAT I DO / HOW I HELP I specialize in: AI Automation (Zapier Automation, Make Automation, n8n Automation) AI Agent Development & Custom AI Agents (including n8n AI Agent, AI Calling Agent, Vapi, and Twilio SMS) Workflow Automation & AI Workflows API Integration & Webhook automation GoHighLevel Automation & CRM Automation Airtable Automation, Notion Automation, and Spreadsheet automation RAG, Langchain, OpenAI, ChatGPT, GPT-4, and Vertex AI powered solutions Custom Automation, Lead Generation Automation, and Business Automation Marketing Automation (Email Campaigns, Email Blast, Appointment Setting) TOOLS I USE EVERY DAY Zapier, Make (Integromat), n8n, GoHighLevel, Airtable, Notion, OpenAI, Langchain, Vapi, Twilio, Webhooks, API Integration, Google Sheets, Notion Dashboard, Notion Workspace, Notion Template, Power Automate, and more. WHO I WORK WITH Founders drowning in repetitive manual tasks, agencies scaling operations, SaaS and eCommerce brands needing smoother AI-powered workflows, sales teams losing deals because their tools and CRM donโ€™t talk to each other, and businesses ready to implement No-Code Automation, Intelligent Automation, and Custom AI Solutions. Letโ€™s transform your workflow into a fully automated, AI agent-powered system. Send me a message today for a consultation, and Iโ€™ll show you how AI automation, AI workflows, and smart integrations can save you time, reduce costs, and unlock your businessโ€™s full potential.

I'm the engineer you hand a vague requirement to and get a working product back. I work as a technical owner โ€” one person covering what most projects need multiple roles for. That means taking your idea from requirements through architecture, backend, full-stack delivery, infrastructure, deployment, and long-term operations. I've delivered over 20 projects this way, including four years as the sole engineer on a live 4G mobile proxy SaaS platform: Android app, Windows/Linux client software, server infrastructure, customer dashboard, and payment processing โ€” all designed, built, and operated by me. What I deliver: โ†’ Backend systems and APIs โ€” Go, Python, RESTful APIs, webhooks, payment pipelines, fintech and telecom integrations (payment card processing, M-Pesa, USSD, SMS gateways) โ†’ Full-stack web and mobile โ€” React, Next.js, Node.js, Android, Tailwind CSS โ†’ Infrastructure and DevOps โ€” Linux, Docker, Proxmox, AWS, GCP, CI/CD, monitoring and alerting โ†’ Data โ€” MySQL, MariaDB, Redis, SQLite โ†’ Embedded and IoT โ€” Arduino, ESP32, Raspberry Pi, MQTT, OpenWrt I work best on projects where scope is forming, requirements are still rough, and you need someone who can figure out the architecture and execute it โ€” not just code to a spec. I'm comfortable owning the full thing end-to-end: from the first planning call through deployment and operations. Ideal engagements: web platforms, SaaS backends, fintech or telecom integrations, mobile apps, infrastructure builds, API design, and systems that need to be reliable in production.

At A Glance: OpenCL

Todayโ€™s modern technology has made it possible to boost productivity, but how do you boost the productivity of technology itself? The answer is OpenCL, a framework for program writing. As an extension to existing languages, OpenCL simplifies the execution process, allowing for commands to be given more promptly and be carried out with more efficiency. In a practical sense, this makes it possible for a video to be transferred in 10 minutes instead of an hour. Harnessing Open CL allows for software, program, and application development to happen in a fraction of the time, thereby creating more efficient programs that deliver better results. Perhaps you wish to take advantage of all this framework has to offer for development and programming, yet you do not have the experience or fluency to do so. The OpenCL specialists on Upwork are here to offer the solution, sharing their experience and skill in OpenCL so you can reap the benefits without the additional effort, resources, and time.

Equipped with outstanding communication skills, these pros ensure clarity and productivity from the first meeting to the last, and theyโ€™re experts in remote work and collaborative efforts. You can entrust this task to their hands, and they can work independently with little guidance, delivering a final result that fits the unique scope or budget of your project. With dozens of specialists available on Upwork, their attention to detail and diverse work histories stack the odds in favor of you finding just the one you need. Browse through the most qualified freelancers, and post a project to receive competitive proposals right away.
