Story arc
How this shipped
End-to-end solutions from database to deploymentThree beats: what pressed against the work, how the stack answered, and what changed once it was live.
I · Constraint
The brief
Matching people with fitness trainers requires weighing incommensurable factors — schedule, budget, personality, goals — in a way that feels trustworthy rather than arbitrary.
II · Build
The craft
Multi-factor weighted scoring with Jaccard similarity for goal overlap, budget constraint logic as a hard filter, schedule conflict detection, and a 0–100 confidence score driven by profile completeness.
III · Proof
What moved after launch
Matching algorithm handles edge cases gracefully. Confidence scoring gives users a clear signal of match quality. Clean UX makes a complex algorithm feel effortless.
