Responsibilities: Led SMT coordination, ensuring alignment with production plans and Key Process Indicators improvements (OEE, customer complaints), Supervised 5 technicians and managed daily production support. Achievements: ● Resolved a $100,000 USD discrepancy in solder paste consumption versus SAP system using 8D problemsolving techniques, addressing a 6-month persistent issue. ● Projected annual savings 10,000 USD by error-proof devices for removing USB port covers for Back-end area ● Led a multidisciplinary team to increase SMT lines OEE by 8% in 3 months through data analysis.

Responsibilities: Directed production scheduling and optimization based on forecasts and customer demand, Led regulatory compliance and cross-functional teams (3 engineers, 4 technicians), Follow-up to OEM requirements Key Achievements: ● Achieved $3M/month in new revenue by leading the successful transfer of Dexcom’s digital glucometer production from San Diego to Guadalajara, deploying four high-volume HLA assembly lines. Utilized full-scale mock-ups to optimize process flow, reduce space by 20%, and boost UPH by 15%. ● Reduced scrap by 25% in Honeywell's wave soldering line by designing standardized SolidWorks wave pallets and integrating pre-solder automated inspection—eliminating a persistent 9-month PCB defect bottleneck. ● Increased monthly revenue by $200K in Dexcom’s lines by raising UPH from 200 to 250 using DMAIC methodology, tooling upgrades, automated scanning (cognex and keyence vision system), and camera-based inspection — replacing manual visual inspection that led to frequent leaks.

Responsibilities: Develops sourcing strategies, negotiates contracts, and manages Supplier relationships for non-production goods and services, including MRO, IT Hardware and special Tools. Achievements: ● Executed strategic procurement leadership by reducing the PSL (Preferred Supplier List) from 120 to 60 suppliers a 50% reduction via data-driven analysis, improving database accuracy and supplier reliability. ● Accomplished a 30% cost reduction in special tooling by aligning commercial agreements with local suppliers and optimizing ERP catalog integration (Baan V). ● Delivered over $900,000 USD in annual savings through standardized designs, standardized materials, RFQ (Request for Quotation), through electronic auctions for strategic segments such as the textile (Nike), electronic (Nokia) and Automotive (Ford, GM, FCA) sectors, since being special product, there was no defined specification.

Responsibilities: Leading the optimization and continuous improvement of production processes, ensuring efficiency, quality and cost reduction for key customer Alcatel Lucent, managed team of 3 engineers and 4 technicians. Achievements: ● Reduced rework and scrap by 85% in Alcatel-Lucent’s assembly area by Implementing intelligent screwing system to avoid missing screws, quality rejects and prevent customer complaints ● Performed SMT line yield from 90% to 99% by optimizing the reflow oven profile as well as redesigning the counterweight and aligner at the same time for a critical component (amplifier), as this problem persisted for several months without a solution. ● Achieved a 20% improvement in process efficiency and ensured customer compliance by coordinating the generation and release of key documentation, including PFMEAs, flowcharts, control plans, work instructions, plant layouts, engineering change notices and Capex budget management.

Responsibilities: Ensuring compliance with Automotive products and process standards by implementing management systems, driving improvements, performing audits, resolving issues Achievements: ● Led operations for five key clients, including EFI Automotive, Tico and Valeo, overcoming challenges in process optimization and customer alignment. Used Core Tools to improve production by 25% through optimized production lines ● Improved Training adherence from 60% to 98%, addressing resistance to change and competency variability. Standardized processes using Flow Charts and FMEA (Failure Mode and Effects Analysis), boosting operational efficiency. ● Increased Customer Satisfaction and Profitability, Enhancement Resolved customer complaints, improving monthly scorecards from 90% to 98%. Applied CAPA, 8D, and Minitab for SPC (Statistical Process Control) and capability studies, achieving a 20% yield improvement and better customer alignment.

Responsibilities: optimizing SMT and Back-end production processes for Huawei and Tellabs Customer, ensuring efficiency and quality. Problem-solving, Supervising 3 engineers and 12 technicians. Achievements: ● Enabled over $2M in quarterly revenue from new Canadian clients by executing the transfer of fiber optic technology from Mexico to Shanghai. Led training for 10 engineers, 5 technicians, and 15 operators to ensure successful production ramp-up at the new site. ● Increased product quality by 20% and productivity by 15%, generating $192K in annual savings by implementing fixture and design improvements, optimizing process flow, and applying Lean methodologies. Introduced fiber optic splicing processes for Tellabs, pioneering this technology within the facility. ● Improved operational efficiency and supported high-volume manufacturing by managing SMT, back-end, and repair operations for Huawei and Tellabs. Oversaw 3 engineers and 12 technicians, driving engineering support and process stability across multiple product lines.

● Improved line productivity by 40% by transforming traditional production layouts into Lean U-shaped cells. Led coordination of the Creedmoor & Telsets shift project with a team of 6 technicians to streamline operations and reduce wasteExecuted the Coordination of shift Creedmoor & Telsets Project with 6 technicians. ● Accelerated time-to-market for new products by executing an average of 5 SMT stencil designs per month and supporting successful prototype builds. Ensured alignment with design intent through early validation of customer documentation including Gerber files, assembly drawings, and specifications. ● Reduced errors and ensured accurate SMT program deployment by coordinating closely with programmers to create and verify machine programs. Cross-checked all SMT programs against BOMs and engineering deviations before release, securing smooth pilot runs and production launches.
