Plain English
Most teams do not have a dashboard problem. They have a trust problem.
When commerce, analytics and ad platforms disagree, the next move becomes political. Arcmedian gives the numbers a review standard: what can be trusted, what needs repair, and what should guide the next commercial decision.
Method
One disciplined route from messy source data to usable judgement.
Reconcile
Compare orders, revenue, traffic and spend across the systems that usually disagree, then isolate the likely cause.
Interpret
Separate genuine commercial movement from tracking drift, platform bias and noisy attribution claims.
Advise
Turn the signal into a short decision memo: what happened, how confident we are, and what deserves action next.
Worked example · Evidence
Not a pitch. A real analysis you can check.

- 1.07mlines audited
- £18.18mreconciled net revenue
- 22.8%attribution gap surfaced
Work

Founder · Analyst
Led by Samandeep Kaur.
I am a data and marketing-intelligence analyst with an MBA in Business Analytics and hands-on reporting experience, including client segmentation and dashboard work that supported double-digit revenue growth at a large media business. Arcmedian is my applied practice and proving ground: the case study on this site is the standard of work I hold myself to.
I am also open to data, MI and analytics roles where I can do this kind of work inside a team. If that is what you are hiring for, the case study is the fastest way to see how I think.
