I build the systems your team runs on: automation pipelines, data workflows, operational tools, and the processes that connect them. I am a senior Qualtrics expert with 5 years of experience working directly at Qualtrics on service and implementation teams. For 8+ years I have designed and implemented systems for SMBs, nonprofits, and universities across the US, Europe, and Australia. The work varies: sometimes a client needs a fully automated delivery pipeline, sometimes a Qualtrics program integrated into their CRM, sometimes an Airtable system to replace five disconnected tools. Most consultants pick a lane: one tool, one layer, one type of problem. That works, until you realize you need three of them and a project manager to coordinate between them. I work differently. I take the problem end to end: understand what is actually broken, design the full solution, and build it myself, with no outsourcing and no hand-offs. The result is a system that connects all the layers, that your team can maintain after I leave, and that was built around your specific workflow rather than adapted from a generic template. โ๏ธ WORKFLOW AUTOMATION I build automation pipelines using Make, n8n, and Zapier, connecting platforms like Salesforce, Airtable, Google Suite, SendGrid, and custom APIs. A lot of this work has nothing to do with surveys: automated client delivery workflows, document generation, CRM update pipelines, data processing systems. When off-the-shelf tools are not the right fit, I also build custom lightweight applications using AI-assisted development, delivered in days rather than months. โ๏ธ DATA SYSTEMS & OPERATIONS I design and build Airtable systems for operations, CRM, project management, and client delivery. I also design process flows and system diagrams for business operations: mapping how work moves, where it breaks, and what a rebuilt version should look like. This is often where automation projects begin, and sometimes it is the whole project. โ๏ธ SURVEY & RESEARCH SYSTEMS [QUALTRICS EXPERT] I spent five years at Qualtrics in senior implementation and operations roles and hold both the CoreXM and CustomerXM certifications. I design CX, EX, and research programs with custom JavaScript logic, workflow automation, CRM integrations, and analytics dashboards. Most clients come to me when Qualtrics needs to do more than collect responses: eligibility screening, automated distribution, branching logic tied to external data, or full program infrastructure built from scratch. WHAT I BUILD โ Automation pipelines across Make, n8n, Zapier, and APIs โ Airtable systems for operations, CRM, and project delivery โ Process design and system diagrams for business operations โ Qualtrics programs with custom logic, integrations, and reporting โ End-to-end data workflows: collection, transformation, storage, output โ Custom lightweight apps when the workflow requires it WHY CLIENTS WORK WITH ME โ I build the complete system, not isolated pieces โ I do the work myself, no outsourcing or hand-offs โ The output is something your team can maintain and build on after handover $1.7M in margin recovery. 120k+ contacts automated. 500k+ feedback records processed.
