01 · The problem

A quick poll or survey usually forces respondents to sign up first, and branching questions ("if yes, ask this next") are awkward to build in simple form tools.

02 · What I built

  1. 01Built a drag-and-drop workflow builder where each question is a node and answers decide the next node.
  2. 02Supported 7 question types: short text, long text, number, rating, yes/no, single choice, and multiple choice.
  3. 03Let participants join anonymously with a room code, with progress saving and duplicate-submission protection.
  4. 04Added scheduled surveys, live voting sessions, and a results dashboard with Excel, CSV, and JSON export.

03 · Decisions & trade-offs

A survey is a graph, not a list

Modelling questions as connected nodes makes branches visible, and the builder can validate the whole flow before it's published.

Anonymous, but one response each

Nobody needs an account to answer, but duplicate submissions are blocked so the results can be trusted.
