I build things.
Enterprise data architecture and physical fabrication. Most jobs need one. Some need both.
Working with complex enterprise systems, designing robust database models, and integrating physical instrumentation, steel, and wood structures from the ground up.
Started at twelve in my father’s shop, welding and working on cars. The tooling has changed more than the job has.
Systems Architecture / Engineering, Strategy, Logistics
Bridging complex data models and compliance governance to empower leadership decisions.
Data & Systems Manager
Direct core data architectures, full-stack database integrations, and machine learning development. Drive business process innovation by integrating advanced Generative AI and LLM workflows alongside traditional analytics to accelerate development and spur growth in Fintech.
- LLM & Generative AI Integration: Architect and deploy custom Large Language Model (LLM) pipelines directly into standard corporate operations, driving automated efficiency, productivity, and Fintech innovation.
- Traditional Dev & Business Analytics: Lead design and deployment of centralized database operations, high-performance ETL systems, and predictive models for high-frequency business analytics.
- Fintech Systems Orchestration: Connect, secure, and sync disparate banking systems, risk-analytics interfaces, and ledger engines into consolidated structural data models.
Senior BI Strategist & Director
Directed BI infrastructure, visual warehouse reporting, and continuous automation pipelines across multiple clinical locations, transforming unstructured operational data into high-value executive dashboards.
- Migration Leadership: Successfully migrated clinical legacy database operations into high-performance SQL models and Power BI visualization suites.
- Reporting Efficiency: Automated distributed clinical report delivery systems, reducing report extraction times by over 90%.
- Technical Mentorship: Trained over 100 system managers on data modeling, systems optimization, and visual analysis.
Capital Projects Coordinator
The move up from plant maintenance: project delivery, and a 30-year capital programme deciding what got built next across three utilities. Better planning for having run the plant it was planning for.
- 30-Year Master Plan: Capital schedule and projected budget at roughly $3B, gated on findings and on funding, with defined off-ramps so a deferred project did not strand the work behind it.
- Capital Planning Manual: Documented the method rather than only the output, so the plan could be re-run by people who had not written it.
- Project Delivery: Ran concurrent capital projects to schedule and budget, coordinating engineering, operations, finance and contractors through the parts where those four disagree.
Plant Maintenance Director
Distribution, motor control and process instrumentation across water, wastewater and stormwater plant. Treatment runs continuously, so the equipment has to start, run and be worked on without taking the process down with it.
- Medium-Voltage Distribution: Transformers up to 15kV, with medium voltage on most motors above 300hp.
- Drives & Starting: Line and load reactors with soft starts or VFDs, sized to the machine rather than to the catalogue.
- Allen-Bradley Process Control: PID loops driven by live process conditions and field instrumentation, not by fixed setpoints someone typed in once.
Plant Engineering
PLC and low-voltage control work on automated material handling, plus the reporting built on what those systems recorded. Where the controls experience started.
- PLC & Control Systems: Programmable logic and 120/480V control work across automated plant equipment.
- Dataset Governance: Pulled operating data off the automated networks into technical reports and engineering budgets, rather than leaving it in the machines that produced it.
President / Owner
Contract SCADA and PLC work, equipment repair, and operational data integration — whatever was broken, or working fine and not talking to anything else. The initials were the pitch: PMI is also preventive maintenance inspection.
- UPS Vendor, Southeast US: One of the leading vendors in the region, trusted with master keys to facilities. Two years later the client became the employer.
- SCADA & PLC: Control systems and equipment repair on other people’s plant, which is where you find out how many ways a thing can be wired before it is wrong.
- Operational Data Integration: Got equipment and software talking to each other — machines that recorded everything and reported nothing, joined to the systems that needed it.
- Running It: Quoting, scheduling and standing behind the work, which is a different skill from doing the work.
Industrial Maintenance Technician / Vice President
My father’s shop. Started at twelve as a welder and an auto tech, left fifteen years later as vice president. Industrial maintenance for other people’s plant, which meant learning equipment by being the one called when it stopped.
- Welding & Auto Tech: Where the hands-on work started, and the reason none of the later plant work was unfamiliar.
- Industrial Maintenance: Asset maintenance and technical infrastructure projects run concurrently for client plant engineering and operations groups.
- Vice President: Quoting, scheduling and delivery for the business, ahead of starting one.
Letters of Marque
A letter of marque made a private ship’s work official without putting anyone on a payroll. This is that: real institutions, real hours, no invoice.
- Current Embedded radio BLE and Wi-Fi on ESP32-S3 Both radios and two cores on one part, which is the appeal.
- 2024 – Present Automation in place M5Stack Small modular hardware put to work on equipment that is already installed, which is a different constraint from designing the control in at the start.
- 2021 – Present Instrument amplifiers The electrical half of the same problem Started a year after the guitars, which is roughly how long it takes to want the whole signal path rather than half of it.
- 2020 – Present Instrument building Acoustic, from raw hardwood Bodies, necks and hardware from stock rather than from kits. An instrument is the one build where being a millimetre out is audible rather than merely wrong.
- 2015 – 2020 Blacksmith instruction Heritage Village, Largo · Pioneer Settlement, St. Petersburg Both settlements across the same five years, not one then the other — it is a small field. Fire, stock, and the difference between hot and hot enough, taught to people holding a hammer for the first time. Teaching a thing is a different skill from doing it, and the quickest way to find out which parts you only thought you understood.
Engineering Proficiencies & Toolkits
Highly versatile technical skill set spanning software development, heavy industrial fabrication, and integrated system assemblies.
