Proteor · Coplay, PA

When Proteor acquired Filament Innovations, my role as CTO carried forward as Lead R&D Engineer.

• Led the design and development of the ICARUS-Lite, a compact industrial printer that automates prosthetic and orthotic production with minimal customer setup. Owned its mechanical, electrical, and software design, including custom AC heaters.Read more
• Owned the ICARUS-Lite through commercialization against unit goals of 60 in 2025 and 100 in 2026.
• Built ExtrusionStudio, a QC and production system live on all three filament extrusion lines since October 2026, taking it from a LabVIEW proof of concept to a Python service. An offset for the 1-2 minute lag between the laser and the spool ties each reading and alarm to the filament being wound, and print-on-demand thermal labels reducing up to 30% of paper waste per run.Read more
• Serve as the technical subject-matter expert across the plant, from industrial electronics on the extrusion lines to low-voltage sensors, and the go-to contact for customer troubleshooting across mechanical faults, electrical faults, and user error.
• Assisted in implementation of ProteorPrintOS with SimplyPrint, enabling remote operation and AI-assisted diagnostics with live video and material, waste, and outcome metrics.
• Developing an offline version of the ICARUS-Lite and ICARUS-Pro control screen, along with over-the-air automated updates, so customers can run without a Wi-Fi or Ethernet connection.
• Co-developed a custom hotend with an outside partner, improving reliability and reducing cost for our materials.
• Managed the Coplay location's Microsoft Business Central ERP implementation in five weeks, migrating more than 2,000 items and 150+ products, reconciling inventory counts on the floor, and syncing SKUs with Proteor's global locations.
• Led the 2026 inventory count in Business Central, tracing discrepancies to production orders that were processed without verification and never took items out of inventory, then assisted in implementation of a more warehouse-focused workflow.
• Estimate and track the budget of every engineering project, build its BOMs, and maintain each product's unit cost in Business Central.
• Present project status, constraints, and budgets at Proteor's monthly USA review with leadership from its global locations.
• Act as Hiring Manager for engineering roles, conducting technical interviews and owning final hiring decisions.
• Performed risk analysis and mitigations to EU and U.S. standards across ProteorPrint hardware and cloud products.
• Re-engineered POSEIDON and ICARUS around one linear-motor motion platform with universal mounts, reaching 4 m/s with 4-micron precision on a 30 kg moving mass.
• Managed and expanded the division's IT infrastructure after the Proteor acquisition, standardizing software and internal processes to align with company-wide systems.Read more

Filament Innovations · Whitehall, PA

Acquired by Proteor and is recognized globally as 'Proteor Print'.

• Oversaw the product-development pipeline, internal IT infrastructure, and technology strategy while retaining hands-on responsibility for mechanical, electrical, firmware, and software systems, and gave the CEO and the company regular updates as designs and software iterated.
• Led the design and launch of the Gen3 POSEIDON, combining a 1 m³ build volume, filament-and-pellet dual extrusion, braked NEMA 34 Z drives, industrial servo XY motion, and a custom gantry.
• Designed and hosted a redundant Kubernetes cluster running a self-developed ERP/CRM for orders, inventory, tasks, projects, and customer interactions, with dynamic BOM generation linked to purchasing.
• Researched high-speed linear motors that moved a 30 kg payload at 3 m/s with 5-micron accuracy and conducted early 6-axis robotic non-planar printing research.

Filament Innovations · Whitehall, PA

• Improved thermal and acoustic performance through enclosure redesign and component placement, including custom tooling with local fabricators for large-radius aluminum-panel bends.
• Integrated a multi-board CAN-bus control architecture that simplified wiring and debugging while supporting larger, modular machines.
• Developed independently testable electronics enclosures that could be installed in minutes and coordinated custom harnesses, panel designs, and hardware improvements with vendors.

Filament Innovations · Whitehall, PA

• Designed and released Kratos, a machine engineered to print high-strength above-knee and below-knee prosthetic sockets.
• Developed next-generation ICARUS and POSEIDON models with higher-performance components and expanded motion safety through NEMA 34 motors, planetary gearboxes, and power-failure brakes.
• Designed THE KRAKEN, a 1 x 2 x 1.5 m hybrid pellet-and-filament gantry printer for a client producing the world's largest 3D-printed statue, and managed CAD, BOM, sourcing, fabrication, assembly, firmware tuning, support, and training.Read more

Filament Innovations · Whitehall, PA

• Diagnosed mechanical and electrical problems during assembly and operation, improving early product reliability.
• Tuned, calibrated, and optimized print parameters while documenting design limitations and opportunities for product improvement.

RJB.Engineering · Pennsylvania

• Deliver project-based engineering support for automotive clients and operate a small online store for 3D-printing heat inserts and other printer accessories.
• Produced 3D-printed plastic face shields during the COVID-19 pandemic.

Carver House Homeowners Association · Pennsylvania

• Manage the banking and monthly insurance payments for an association of about 80 units.
• Help establish a community-focused member board in place of a property management company, remaining Treasurer through a mid-year restructure.

Blue Mountain Ski Resort · Palmerton, PA

• Operated lifts and assisted thousands of guests with ticketing, weather, and slope information.
• Performed motor and control safety checks and supported the maintenance team during lift breakdowns.

Northampton Area School District · Northampton, PA

• Built network infrastructure and deployed more than 750 wireless access points across six school buildings.
• Accelerated deployment of more than 2,500 Chromebooks by developing an Arduino-based tool to automate setup-data entry.
• Coordinated final device distribution with school administrators.
