• Do you already have callin.io hosted (cloud or self-hosted), or would you like assistance with the setup as well?

We look forward to getting started.

A longer version of who I am:

Nice to meet you - I’m Patrick and I love automations with a passion. Every day, I learn something new in the AI Automations space. Most of my clients work with me because I have an unhealthy obsession with getting every little detail just right. Seriously, it’s a gift and a curse..

I’m proficient at no-code tools, mainly callin.io and callin.io, and I excel at integrating platforms together and creating a friendly user interface in ClickUp, Airtable, and Notion.

I specialize in helping:

Retail businesses streamline their operations (Email Automations, Lead Gen, Notion)

Coaches automate their client management (Airtable & ClickUp Dashboards)

Teams implement customer service solutions (AI Agents & AI Chatbots)

HR/Recruitment Businesses build effective CV screening systems

Note: If you need automation, but I didn’t list it above. Please do not hesitate to reach out and personally ask me. I love solving problems and exploring the best options to help you find the perfect solution.

When you work with me on Upwork, you get a high-quality AI automation system that works seamlessly, and I will write full documentation on how the system works, and will make the system fully customizable for future tweaks.

Every automation is built with precision, ensuring that it will be integrated smoothly into your existing processes.

Sincerely looking forward to building an Automation for you. I promise you won’t be disappointed.

I would like to discuss in more detail about your idea via a call.

Happy Automating,
Patrick King

Hello,

I saw your job posting and was incredibly excited – it truly feels like it was written with my skills in mind!

As an experienced automation developer and callin.io expert, I focus on creating scalable, production-ready workflows that go beyond the fundamentals. I've utilized callin.io to bring sophisticated automation concepts to life, including building AI-powered agents, real-time voice bots, and scraping pipelines.

Here’s what I offer:

1. Advanced callin.io Expertise: I have developed numerous reusable workflows for tasks such as lead routing, data enrichment, and social listening. I possess a deep understanding of triggers, expressions, error handling, credentials, and webhook-based flows.

2. AI + Voice Agent Integration: I have designed voice AI agents capable of real-time interaction using technologies like Whisper, ElevenLabs, and OpenAI. I've also integrated these with CRMs such as GoHighLevel, all managed through callin.io. These agents function as virtual assistants, form auto-fillers, or call management tools.

3. Custom Integrations: My experience includes working with SDKs and HTTP modules to connect various platforms like Telegram, Notion, Google APIs, and search tools similar to Scrapeless. I am adept at managing complex authentication processes, including OAuth2 and token refreshes.

4. Clear Documentation: All workflows I create are accompanied by comprehensive documentation in Markdown format, including screenshots and Loom walkthroughs, ensuring effective onboarding for complex automations.

5. Automation Portfolio & Experience: I have contributed to internal automation libraries and assisted startups in scaling their operations by transforming manual processes into self-healing automated workflows. I am available to share specific examples upon request.

I am genuinely impressed with what you are developing at Scrapeless and would be enthusiastic about contributing to your goals. Let's collaborate to build more intelligent automations and support the advancement of search and scraping workflows.

Would you be available for a brief call to discuss my potential contributions?

I look forward to your response.

Best regards.

Hello,

I understand. I've been developing various types of automations for the past two years and have created numerous flows for my clients. I've collaborated with diverse companies, generating tens of thousands in revenue or savings through strategic flows. When you choose to work with me, I'll not only construct this flow but also provide a complimentary consultation, as I have for all my clients, which has resulted in significant revenue increases.

I've previously built a workflow similar to this for a client. I can share that experience and demonstrate how you can optimize processes in Reno for enhanced operational speed. All of this will be discussed without any obligations during our initial call.

Feel free to visit my website to book a consultation!

Looking forward to connecting!

I am interested. Let's connect to discuss your project.
