Blade Cost Reduction

• Led cost reduction trials for high cost custom blades used in APM machines, with lower cost alternatives, projecting $20,000+ in annual savings.
• Conducted operator interviews to assess blade failure modes, replacement frequency, and operational challenges.
• Tested multiple blade assemblies focusing on durability and compatibility.

Rework Process Optimization

• Conducted a comprehensive analysis of the membrane rework process across production areas identifying inefficiencies in documentation, traceability, and communication.
• Interviewed operators and teams lead to understand of pain points in the DMR (Defective Material Report) process, revealing that ~20% of rework lacked proper MES documentation, leading to miscommunication and redundant rework.

Vent Hood Airflow Study

• Investigated glycerin drip issues at AMEC 19 by analyzing airflow dynamics and thermal conditions across multiple AMEC generations (GEN 1–3).
• Collected and analyzed quantitative data measuring: Airflow rates at 6" ducts (avg. 667–1,376 fpm) Surface temperatures across vent hood components (front, rear plenum, scrim, ductwork).
• Created structured spreadsheets to log and compare airflow and temperature data across GEN 1–3 AMEC units.
• Identified potential causes of front-drip accumulation, including suboptimal airflow distribution and dew point differentials between fabrication and membrane environments.
• Recommended vent hood redesigns to improve airflow and eliminate condensation zones.

• Work with field survey crews performing preliminary, construction surveys, and as-built surveys.
• Use GPS equipment, robotic total stations, and grade rods to take measurements on construction sites.
• Make tabulations and computations related to land surveying and roadway design.
• Assist with reading and interpreting construction plan sets to be used for field staking, measuring, and marking.
• Assist with creating design plans using survey data collected in the field.
