After SolarSCADA was acquired by Skyfri, I moved from Garage Greg into the role of SVP of hardware engineering within Skyfri, where I continue to develop our purpose-built PV-Specific SCADA hardware integration solutions.

Linder Engineering is a multidisciplinary engineering consulting business. We develops custom equipment for a wide range of industries. I currently support our existing customers, but our primary focus is SolarSCADA through hardware development to address various shortcomings in the PV SCADA industry.

SolarSCADA offers an IEC-61724-1 compliant full turnkey, highly modular, solar Supervisory Control and Data Acquisition platform. We've got high speed data, web access, cell connectivity, VPN access, email reporting, automatic alarms, custom dashboards, all kinds of great stuff. We've more than doubled every year since founding, and our system at the close of 2021 span 6 states and close to 60MW of interactive, controllable PV resources.

While at Kleinfelder, I assisted in solar system design and validation, and supported their efforts for ADAS system install for reservoir monitoring. While no longer employed by Kleinfelder, I still support some of the work I did through Linder Engineering Works, as I believe long-term support of valuable assets is key to infrastructure projects.This includes interfacing for vibrating wire piezometers, wireless radio setup and site planning, and SCADA data integration. In general, once the wires to the sensor leave the borehole, ground, cabinet, or system, I implement solutions to turn those raw analog signals into actionable intelligence available via whatever means are required for the various projects, be they web, SCADA-system, CSV file, or otherwise.

I was responsible for the design, commissioning, and operations of the Supervisory Control and Data Acquisition (SCADA) system monitoring Juwi's utility-scale solar generating assets. Under my supervision, the system peaked monitoring nearly 300 MW of PV capacity in several different states, using multiple brands of tracking systems, inverters and data interoperability systems. The system I designed supports a dozen users, and provides end-to-end DC and AC performance measurements down to the string level, with meter-grade accuracy throughout the system.

On my way to finishing my MS Thesis, entitled "Failure Analysis and Smart Grid Control Protocols for Anaerobic Digesters", I redesigned, built, and operated a 500-gallon portable anaerobic digester. This digester consists of heating loops, manure loops, and interface valves for feeding and draining. It also included a SCADA system for monitoring and logging system performance metrics, including tank temperature, gas quality and production, and energy use. Much of the raw data from this project was used for other research projects analyzing the effect of digesters on different feedstocks and operating regimes.

I assisted with field installs, commissioning, and system documentation for dual-axis tracking photovoltaic generating systems. I also wrote internal documentation for telemetry and control systems.

I performed system installation and commissioning for building-integrated lighting control equipment, including customer training. I was also responsible for the repair of customer equipment as well as the repair of Chicago Spotlight's very large rental inventory of dimmers, follow spots, and lighting control equipment.Part of this job as being an on-call service person, where my collection of well-worn tools and extremely fast on-the-job thinking were able to address several problems that I may not have been trained to do. When the show starts in 30 minutes, and you're broadcasting live, you need to be able to think quickly to fix the problem, no matter who supplied the equipment.

I designed firmware for a family of battery equalizers, built and prototyped a family of battery data logging products, and designed and constructed systems for accelerated life cycle testing of batteries, including both water-immersion and "hot-box" style environmental chambers.

Controls team leader for the design of experimental high-efficiency 500 watt variable frequency drive based on a controller from Microchip's PIC18 Family. I wrote all the firmware in assembly language, and hand build several generations of prototype motor drives, ranging from hand-soldered to finished PCB.

During my undergraduate years, I worked on and off at UIUC's x-ray diffraction laboratory, fixing crystallography equipment, upgrading networking gear, and moving around extremely heavy dangerous things using simple machines.

I was in charge of various systems for the Sunswift II and eventually the Sunswift III solar cars at University of New South Wales. My tasks here included everything from helping with bellcrank design for steering systems to assembling surface-mount MPPT boards to researching and implementing tooling techniques for solar cars, including high-temp autoclave procedures and release agent testing and specifications.

During my undergraduate years, I worked several summers at Fermi National Accelerator lab, performing tasks related to engineering on the Next Linear Collider (NLC) project. My main tasks involved laboratory work testing radio frequency accelerator structures. This included designing a new semi-automatic testing system to simply and reliably apply the appropriate force needed to get good RF contact between antenna surfaces while operating a clean-room environment. Once this machine was done, I spent a lot of time using it to run experiments on waveguides and accelerating structures.The result of this work was my first conference paper, a presentation on bead-pull testing for accelerating structures.While at Fermilab, I also assisted with the installation and commissioning of a large vacuum brazing furnace, which included a lot of work doing leak checking of the vacuum systems. When not occupied with my other tasks, I sought out work using my classic computer skills, finding the last VAX at Fermilab, restoring it to operation, re-installing VAX/VMS and digging through archival TK50 and TK70 magnetic tapes searching for magnet test data from the Magnet Test Division's early 1980s testing systems.

I worked in the University's X-ray crystallography lab, restoring a 1980's PDP-11 driven Enraf-Nonius Cad4 diffractometer to service, including rebuilding the X-Ray source, repairing the control computer, and re-wiring and re-plumbing considerable parts of the system.Once the machine was fixed, I Designed and built in-situ platinum polishing attachment for the kappa-geometry machine, which has certain benefits for this over a full-circle style goniometer.

I spent four months in Germany as a machinists' apprentace, learning the basics of production machining on equipment including cam driven mechanical multiple-spindle machines and state of the art software programmable multi-axis machining centers. I worked in each department on the shop floor, learning about quality control, G-code programming, finishing steps, part washing, and optical inspection. Additionally, I was responsible for running prototype small part runs of a new design of threaded insert, from drawing through to final washing.

My tasks here were basically what you would do as an electrician at any theater: We were primarily an ETC Shop with Source 4's, and Colortran Zooms (and mini-zooms, yay) from a previous generation, plus the typical random assortment of 6x9s, pars, and fresnels. I maintained much of this inventory, as well as our hydraulic pit lift and audio system.As a road-house, we had touring shows come in. As a fly rail operator, I flew in Chinese acrobats, ran the ropes for the Joffrey Ballet's touring company, and acted as a puppet operator for our own monster creation for the plant in Little shop of Horrors. I also fixed a leaking levitating woman magic trick, and spent countless hours cutting, painting, and building set pieces.
