About Me

Building Business Automations That Make a Real Difference

Most businesses lose dozens of hours each week to repetitive manual tasks: copying records between spreadsheets, forwarding leads, and generating reports. As an independent automation engineer, I design bulletproof, scalable pipelines that bridge your tools—saving time, eliminating human error, and lowering operating overhead.

Frequently Asked Questions

Clear answers regarding turnaround times, architecture, and post-launch support.

What types of business processes can you automate?+

Virtually any repetitive task your team performs manually: cross-system data synchronization, lead routing and CRM updates, email sequences, report generation, invoice processing, PDF document extraction, and team alerts. If there is a defined business rule, it can be automated.

Do I need to pay monthly subscriptions for automation tools?+

Not necessarily. While cloud tools like Make or Zapier charge monthly fees that increase with your task volume, I specialize in self-hosted tools like n8n and Docker. This means your automation runs on your own server with no per-task fees and unlimited executions.

Is the AI implementation secure and private?+

Yes. I offer self-hosted, local AI models (using Ollama and private vector databases) that run strictly on your own secure infrastructure. No proprietary client documents or customer records are ever sent to third-party AI APIs.

How does fixed pricing work?+

Following a brief 30-minute discovery call, you receive a written proposal within 24 hours outlining the full scope, exact deliverables, timeline, and a single fixed price. No surprise hourly billing.

What post-launch support do you provide?+

Every project includes full technical documentation, a recorded video walkthrough for your team, and 30 days of post-launch warranty support. If anything requires adjustment, it gets fixed promptly.
