I am a senior database, data architecture, and BI consultant with 42 years of experience designing business systems, databases, data warehouses, integrations, and analytics solutions across industries such as retail, SaaS, healthcare, asset management, banking, manufacturing, services, e-commerce, and finance.
My strongest value is connecting business needs with reliable technical architecture. I help clients move from scattered data, fragile reports, and manual processes to analytical environments that are fast, reliable, maintainable, and ready for BI or AI.
Core strengths
• Database architecture, SQL, performance tuning, and data modeling
• Data warehouse design, ETL/ELT, and automated data pipelines
• Power BI dashboards, semantic models, DAX, and Power Query
• BigQuery, SQL Server, SingleStore, PostgreSQL, MySQL, Oracle, and Microsoft Fabric
• Python, APIs, Google Cloud, AWS, Azure, and cloud-based data workflows
• KPI definition, metric validation, executive reporting, and AI-ready data layers
Unlike many dashboard-focused consultants, I come from a deep database and systems background. I design the structure behind the report: schemas, relationships, ETL routines, indexing strategy, validation rules, semantic models, and performance optimization. This helps clients avoid fragile dashboards built on messy data and instead create a solid data foundation for reporting, analytics, and AI.
AI-ready data architecture
Many companies try to connect AI directly to raw databases, but that often creates slow, expensive, and unreliable answers. My approach is different: I build governed analytical layers where definitions, relationships, KPIs, and business rules are explicit.
This improves trust, reduces cost, increases performance, and allows AI to work with business-approved metrics rather than guessing from raw tables.
Recent project examples
- Database Performance / DBA Leadership
I am responsible as DBA and Database Lead for a massive infrastructure using SingleStore and SQL Server, working at billion-record scale with the responsibility to deliver query results in less than 1 second. This involves database design, indexing strategy, stored procedures, and continuous optimization of high-volume workloads.
- AI-Connected Semantic Model with Power BI and Claude
I designed a cloud-based analytical solution using Cloud Run, Python, GitHub/Artifacts, Cloud Scheduler, BigQuery, and Power BI semantic models, enabling Claude to connect to governed business data. The solution included specialized skills to query the semantic model, respect business rules, and provide accurate answers with high performance and data reliability.
- AI Data Enrichment on Google Cloud
I designed and implemented a serverless AI enrichment pipeline using Google Cloud Run, Cloud Tasks, Cloud Scheduler, Python, and BigQuery. The client needed to enrich millions of company records using GROK AI within a tight processing window while controlling BigQuery costs. The result was millions of enrichment tasks completed within SLA, stable throughput, structured validation, and more than 90% reduction in BigQuery costs.
- IoT Data Aggregation with BigQuery
I built a Google Cloud solution to collect high-frequency sensor data from thousands of sensors through an API every three minutes. The architecture used Cloud Run, Python, GitHub/Artifacts, Cloud Scheduler, and BigQuery, creating an automated and scalable data warehouse process running for months without manual intervention.
- SaaS Product Analytics
For a SaaS company, I transformed complex Firebase / Firestore JSON data into structured analytical tables in BigQuery. I created the ETL routines, designed the analytical foundation, and delivered Power BI dashboards for product usage, engagement, trial behavior, feature adoption, and conversion analysis.
- Retail Operations Reporting
I built an automated reporting system for a large restaurant chain, processing POS data with Python ETL, cloud automation, AWS infrastructure, and Power BI applications. The system delivered daily KPI reporting for sales, revenue, labor, service times, customer behavior, and operational performance.
- Asset Management Analytics
I developed a portfolio monitoring solution using Python ETL, Reorg API, AWS, database design, and Power BI. The solution tracked liquidity, EBITDA, leverage, and other investment KPIs, giving the client daily updated information for portfolio analysis and decision-making.

I build the systems your team runs on: automation pipelines, AI-integrated workflows, data systems, and the Qualtrics programs and operational tools 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 built 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 an AI layer that reads and sorts incoming work, 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 realise 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. You work with one person who owns the outcome from the first call to handover, rather than being passed between a sales lead, a project manager, and a rotating cast of subcontractors. On complex, production-grade AI builds I partner with a senior AI architect I work with directly, which adds staff-level engineering depth while keeping that single point of contact intact. The result is a system built around your specific workflow, that your team can maintain after I leave.
⚙️ 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.
⚙️ AI INTEGRATION
I build AI into the systems you already run, wherever it removes manual work or surfaces the answers you need faster. I stay tool-agnostic, using Claude, the OpenAI API, or custom builds depending on the job, rather than forcing one approach onto every problem. In practice that has meant reading and triaging incoming emails and form submissions, pulling clean structured data out of PDFs and thousands of open-text responses, auto-generating branded reports straight from a data source, and scoring or screening applications against set criteria. For complex, production-grade work I partner with a senior AI architect, so what I hand over is reliable enough to run unattended rather than a clever demo that breaks in week two.
⚙️ 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.
⚙️ 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:
→ Automation pipelines across Make, n8n, Zapier, and APIs
→ AI integrations: triage, data extraction, automated reporting, scoring and screening
→ Airtable systems for operations, CRM, and project delivery
→ Process design and system diagrams for business operations
→ Qualtrics programs with custom logic, integrations, and reporting
→ End-to-end data workflows: collection, transformation, storage, output
→ Custom lightweight apps when the workflow requires it
WHY CLIENTS WORK WITH ME:
→ I build the complete system, not isolated pieces
→ One accountable owner from scope to handover, never passed around a team
→ Staff-level AI engineering on complex builds, through a senior architect I partner with
→ The output is something your team can maintain and build on after handover
