ClickTrail
Keep campaign links healthy and attribution intact.
ClickTrail brings branded links and QR codes together with destination checks and campaign analytics. Shared rules for campaign tracking tags (UTM parameters) keep campaign context attached to clicks and conversions.
My role
Ketrium Labs · co-founder and engineer
Contribution and scope
I co-architected and built link creation, workspaces and roles, event ingestion, caching and aggregation, APIs, webhooks, and production operations.

Problem
Campaign links need to stay trustworthy after they are published: destinations can break, redirects or SSL can fail, and tracking parameters can disappear before attribution is recorded.

Design considerations
Tradeoffs suggested by the documented capabilities.
Treat link health as part of the campaign path
A destination, SSL, or redirect problem can break the experience before analytics can help.
Tradeoff: Health checks need to reflect real redirects and domains without creating noisy warnings.
Keep workspace boundaries visible
Workspaces, roles, auditability, and custom domains belong to the product model, not just the settings screen.
Tradeoff: Shared analytics and link infrastructure must preserve tenant scope at every boundary.
Challenges
- Checking redirects and destination health across custom domains.
- Keeping UTM context intact as clicks move through a redirect chain.
- Separating workspace data while supporting shared event aggregation.
What shipped
- Shipped branded short links, QR codes, UTM governance, workspaces, and role-based access.
- Implemented Redis-backed caching and aggregation for click analytics.
- Built checks for broken destinations, SSL and redirect issues, and stripped tracking parameters.
- Connected campaign activity to conversion and revenue attribution.
