Engineering and advanced manufacturing work

Daniel’s engineering record is grounded in real equipment, safety constraints, production pressure, and the need to explain what happened clearly.

01

Battery systems and fault investigation

At Rivian, Daniel charged, discharged, pressure-tested, moved, inspected, and helped repair sealed electric-vehicle battery assemblies. He used an overhead crane, documented internal parts and equipment with DSLR photography, helped maintain chain-of-custody records, and contributed findings intended to improve future pack reliability.

The work also included specialized line-equipment wiring, PLC-related controllers and harnesses, emergency response, technical documentation, and cross-team communication.

02

Production improvement

At Morton Industries, Daniel operated an LT Fiber Evo on an independent weekend shift. He describes applying 5 Whys, Lean, Six Sigma, and Gemba Kaizen methods to order sequencing and material use. Batching 50-plus orders at once helped maximize stock utilization and prepare more production crates while limiting waste.

At The Wassi Group, he independently transported and operated more than $20,000 in architectural scanning equipment at client sites and managed plan-printing, conversion, binding, supplies, and delivery workflows.

03

Advanced manufacturing interests

Beyond direct work history, Daniel explores semiconductor manufacturing, lithography, photonics, additive processes, automated fabrication, and unconventional computing structures.

04

Safety, traceability, and handoff

Manufacturing improvement is durable only when the safe method, material state, equipment condition, inspection result, and reason for a change can be handed to the next person. Daniel’s experience with battery chain-of-custody records, technical photography, production sequencing, and client-site equipment reflects that operational side of engineering.

The same principle shapes his research interests: a novel device or process becomes more credible when its tolerances, failure modes, measurement method, and limits are documented alongside the design.
