Experience

Project Engineer · Sausal Corp

Apr 2024 – Present
  • DSupported project execution by coordinating with field teams, subcontractors, and engineers to track progress, resolve site issues, and maintain project schedules.
  • Assisted with RFIs, submittals, and documentation control to ensure accurate communication between design intent and field implementation.
  • Helped monitor job site activities and project data to identify delays, support issue resolution, and improve workflow efficiency across construction phases.

R&D Team (Medical Devices) · URAP, UC Berkeley

Jan 2023 – Dec 2023
  • Co-developed neonatal peritoneal dialysis system; coordinated electrical & mechanical subteams on mechanisms, sensors, and safety.
  • Executed 80+ DOE trials optimizing flow rates, tubing, and valve timing — achieved <5% variance in flow stability and >98% sensor accuracy.
  • Led benchtop test setup with pressure/weight/flow instrumentation; created test plans, calibration, and validation reports.

Projects

Toroidal propeller experiment

Toroidal Propeller

Problem: Reduce acoustic noise and improve thrust efficiency.

Approach: CAD, prototyping, sensorized thrust stand; MATLAB analysis.

Result: 3–4 dBA noise reduction, 3–6% efficiency gain at mid-RPM.

Open case study
Automatic water dispenser

Automatic Water Dispenser (IoT)

Problem: Manual irrigation caused inconsistent plant health.

Approach: ESP32, soil sensors, control thresholds, enclosure design.

Result: Reliable moisture levels, healthier plants, serviceable design.

Open case study
Automatic writing arm

Automatic Writing Arm

Problem: Increase fidelity of GUI-generated paths.

Approach: Kinematics, backlash reduction, calibration, filtering.

Result: 95% path accuracy, smoother motion traces.

Open case study
Water bottle holder

Water Bottle Holder

Problem: Lack of secure, ergonomic everyday carry.

Approach: Iterative CAD → print → test, ergonomic studies.

Result: Lightweight design with compartments for phone, card, AirTag.

Open case study
Bike design

Bike Design

Problem: Optimize frame strength-to-weight.

Approach: Parts modeled in Creo; animated design video using 3ds Max.

Result: Balanced performance and cost; documented design trade-offs and presentation visuals.
