The project

Stackwise helps engineers explore how part variation affects an assembly. It supports signed tolerance chains, worst-case and RSS analysis, Monte Carlo simulation, mixed units, contribution rankings, capability metrics, saved projects, imports, and exportable reports.

What I contributed

  • Set the product direction and developed the interface, analysis workflows, brand, documentation, and supporting product pages.
  • Designed a progressive workflow that starts with simple stacks and reveals advanced distributions, correlation, yield, sensitivity, and optimization tools when needed.
  • Built around transparent calculations and clearly labels the tool as a preliminary engineering aid rather than a substitute for a complete GD&T review.

What I have gained

  • Translating engineering math into an interface that explains results instead of only displaying numbers.
  • Managing a growing product across calculations, data import, visualization, reports, persistence, and responsive design.
  • Designing guardrails and model-health checks for decisions that can affect real manufactured parts.
  • Owning both technical implementation and the way a product is positioned and communicated.

Where it is going

Current focus

Expanding advanced analysis while keeping the first-use experience approachable.

Next step

Validate more real-world workflows and keep improving the path from a result to a practical design decision.
