      Gardena, California, United States As 3DEO's first application engineer I owned all customer-facing technical communication, model/drawing analysis and DfAM engagement, pricing for all deals, as well as technical program management after deal close— from process development, to first-article submission or PPAP, through serial production across 130+ unique parts and 50+ customers in one year. Over the course of one year: - 600% growth in monthly incoming revenue. - 750% growth in booked ARR. - 400% growth in… Show more As 3DEO's first application engineer I owned all customer-facing technical communication, model/drawing analysis and DfAM engagement, pricing for all deals, as well as technical program management after deal close— from process development, to first-article submission or PPAP, through serial production across 130+ unique parts and 50+ customers in one year. Over the course of one year: - 600% growth in monthly incoming revenue. - 750% growth in booked ARR. - 400% growth in unique parts. - Two MPIF Design Excellency Awards I built from scratch the internal system which housed version and access controlled part and PO data for the entire company, interfacing with management, sales, engineering, and operations stakeholders to script automated dashboards. Over an eight month lifetime this system booked 100+ unique SKUs representing $2.2M in revenue and 300,000+ parts ordered. Accomplished the above while working fully remote for 6+ months during the 2020 COVID pandemic.
