Pile cloth media filtration systems for municipal water reclamation

• Own the technical scope for preconstruction on assigned projects, including sizing and configuration of pile cloth media filtration systems, budgetary proposals, competitive bids, and full equipment submittals
• Author and maintain acceptance and commissioning documentation that field crews execute without engineering supervision, including per item maintenance matrices, long term storage requirement procedures, and operations and maintenance sections, so that outcomes are consistent across sites and crews
• Manage and track the submittal process end to end, verifying that every document is accurate, complete, and aligned with project specifications and delivery schedules before it reaches the customer and the engineer of record
• Review instrumentation and control documentation across radar level transmitters, float switches, vacuum transmitters, turbidity and solids analyzers, variable frequency drives, and local control panels, resolving tag discrepancies and open RFIs directly with the design engineer
• Perform onsite equipment receiving, inspection, and field verification at installed sites, identifying damage, configuration errors, and documentation mismatches before they become field failures
• Coordinate with sales, engineering, and vendors through procurement to keep equipment accurate and delivered on schedule, including managing an international shipment against a fixed project milestone
• Build reusable internal reference material, including a running technical standards document that captures sizing rules, component selection logic, and pricing methodology so that proposals stay consistent as the team grows

• Cleaned and restructured electronic medical record data, reducing duplicate records and improving query reliability by 40 percent
• Built a tracking system covering 500 or more records across intake, consultation, and conversion stages, giving leadership visibility into throughput and drop off by stage for the first time
• Reorganized records to enable reliable transfer between systems that previously required manual reconciliation

Medical device startup

• Conducted root cause analysis on a prototype system to localize failures to hardware versus software, isolating the responsible subsystem before escalating to the responsible engineer
• Independently designed, prototyped, and iterated a robotic assembly solution deployed on the production bench in a startup environment with no existing automation
• Executed human factors testing protocols supporting an FDA 510(k) regulatory submission, running scripted procedures with structured data capture against predefined pass criteria
• Designed 3D printed fixtures and tooling in SOLIDWORKS to reduce assembly time and remove operator variability
