Where I Add Value

Durability & Maintainability

  • PE Approved civil designs

  • Vibration and crash robustness, materials/coatings for UV, salt, thermal exposure

  • Serviceable fastener strategy (inserts, torque specs, locking mechanisms, easy release mechanisms)

Rapid iteration & DFM

  • CAD → bench prototype

  • GD&T and tolerance stacks tied to build variation

  • DFM; costed BOM; simple jigs/fixtures

  • Targeted FEA to de-risk decisions

Evidence-driven Validation Testing

  • Test plans with pass/fail criteria

  • DOE where it reduces risk/cost

  • Data logging & quick scripts (MATLAB)

  • Validation testing → supplier hand-off (first-article/tooling feedback)

FEATURED PROJECTS: Results-first case studies—click through for constraints, process, and tests.

  • NDA-limited mobile X-ray scanning system tile (public render; details sanitized).

    Mobile X-ray Scanning System (NDA-limited)

    Key mechanical designer; composites & brackets; no structural failures across 5 field installs

  • DA-limited project badge

    Underwater Acoustic Tag Packaging (NDA-limited)

    Low-profile molded housing; tuned CG; passed pressure checks ; longer runtime.

From Problem to Design Transfer

Step 1 — Discover

Define users, constraints, environment, and product requirements; capture risks.

Deliverables: requirements meeting; test plan v0.

Step 2 — Design

CAD with GD&T; back-of-envelope calcs and targeted FEA; tolerance stacks grounded in real build variation.

Deliverables: design review notes; drawings + tolerance map.

Step 3 — Build

Rapid prototypes; DFM considered early; simple jigs/fixtures; costed BOM and supplier RFQs.

Hands-on options as needed: 3D printing (FDM/SLA), silicone tooling & urethane casting for low-volume.

Deliverables: prototype with photos/video; costed BOM; initial supplier feedback.

Step 4 — Verify & Hand-off

Run ingress-protection (IP), impact/drop, and thermal checks as appropriate (add vibration when relevant); log data vs. requirements; fold fixes into next rev and prepare supplier hand-off (RFQs, drawings/BOMs pack, first-article/tooling feedback).

Deliverables: test report with pass/fail & next actions; DFM package for suppliers.

Mechanical design: CAD (Fusion 360, Onshape, SolidWorks); GD&T; tolerance stacks

Prototyping: 3D printing (FDM/SLA); soft tooling; quick jigs/fixtures; hand tools

Validation testing: structured test plans; pass/fail; ingress-protection (IP), impact & vibration checks; basic data logging

DFM/DFMA: costed BOMs; vendor quotes; build docs & ECOs; tooling liaison (RFQs, DFM reviews, first-article/tooling feedback)

Electromechanical: sensors & actuators (solenoids, servos); Arduino; wiring/harnessing; safety interlocks (e-stop states)

Execution: schedules & risk tracking; design reviews; clean design transfer and supplier handoffs

About Molly

I’m a mechanical engineer focused on product development for mechanisms, enclosures, and electromechanical assemblies. I turn requirements into shipped hardware with evidence-driven prototyping, SolidWorks/ANSYS FEA, supplier-facing DFM/DFMA, and PLM (Arena) for BOM/ECO control. I own design transfer—clean handoffs and first-article/tooling feedback—and design for serviceability, cost, and scale. Open to roles in consumer, industrial, and R&D hardware

Let’s Connect

Employers & hiring teams: I’m exploring product-development roles in consumer, industrial, and R&D hardware. Best fit: concept → prototype → validation testing → DFM→ design transfer; mechanisms, enclosures, and electromechanical assemblies; supplier liaison for molded, machined, and sheet-metal parts. If you’re shipping hardware and need clean design transfer and supplier handoffs, let’s talk.
