A live product, public page, or access-ready prototype.
Product/UX Diagnostic
Find the problems worth fixing first.
I review one defined product experience, identify the 5–10 issues most likely to create friction, confusion, or lost momentum, and give you the three actions I’d prioritize first.
No meeting required. No ongoing commitment. One decision-ready review.
Where is this flow losing clarity, trust, or momentum?
Timing starts after payment and complete intake.
What you receive
A clear priority order for your team.
The diagnostic is deliberately small. It gives you enough evidence to decide what matters now—without pretending a one-day expert review is user research or a full product audit.
5–10 prioritized findings
Each observation connects visible evidence to the friction or risk it creates.
Three actions worth taking first
A short priority order so your team knows where to focus before spending more.
Annotated evidence
A concise PDF or web report with screenshots or frames where they help.
A hard boundary protects the value
What is—and is not—included.
Included
- One public product, prototype, or access-ready experience
- One primary user goal or flow
- Up to five key screens, pages, or states
- 5–10 prioritized observations
- Top three recommended actions
- Concise annotated report delivered by email
Not included
- Full-site, full-app, or multi-role review
- User interviews, analytics investigation, competitor research, or usability testing
- Redesign, Figma production, code review, implementation, or engineering estimates
- Accessibility certification or legal/compliance review
- Meetings, revisions, ongoing consultation, or guaranteed commercial outcomes
How it works
From uncertainty to a clear first move.
Choose the flow
Send one URL, prototype, or set of screenshots and name the user’s goal.
Give me the context
Tell me the outcome that matters and what you suspect is not working.
I review it
I inspect the experience through product, usability, trust, and interaction lenses.
You get priorities
By the next business day, you receive the findings and the three actions I’d take first.
See how I think
Evidence → consequence → fix.
The sample audit is a composite specimen, not a client result. It shows the structure and judgment you can expect without manufacturing proof.
Need a whole flow walked, not five screens? The UX Teardown · $350 ranks its five biggest leaks in 48 hours. A full improvement plan for one flow: the Critical Flow Audit · $550, with a walkthrough call. The whole product: the Full Product Audit · $850.
Example structure
Observation
What is visibly happening in the product experience.
Why it matters
The likely cost to comprehension, trust, momentum, or completion.
Recommended action
A concrete next move, bounded by what the evidence can support.
Fit check
Start with the work you need.
This fits if…
- You have a live or clickable experience.
- One user goal matters right now.
- You need independent priorities before a larger investment.
Discuss a different scope if…
- You need a complete flow or whole-product review.
- You want a walkthrough, revisions, or strategic collaboration.
- You need research, testing, redesign, or implementation.

Start your diagnostic
Checkout. Then a short intake form.
Two steps: pay through Stripe, then fill in the short intake form that opens when checkout completes. Delivery starts after payment is verified and the complete brief has arrived.
Not sure the scope fits? Ask before paying →
1. Pay for the diagnostic
One user goal, up to five screens or states. $200 USD, excluding applicable taxes.
Payment happens on Stripe. Opening checkout does not confirm a purchase.
2. Send your brief
Checkout returns you to a five-field intake form. Prefer email? Use the same email address as checkout and include:
- An access-ready product or prototype link
- The primary user goal
- The business or product outcome you want to improve
- Your main concern and useful context, if any
This opens a draft in your email app; you review it and send it yourself. You can also email the checklist directly to josue@perex.design. Do not send passwords or sensitive personal data.
Already paid? Open the intake form or send the brief by email; do not pay again. I’ll confirm receipt and your delivery date by email.
Practical details
Before you start.
When does “next business day” begin?
After payment and all required intake material have arrived, subject to the 17:00 Europe/Madrid cutoff. Weekends, Spanish public holidays, and major U.S. holidays are excluded.
Is this user research or usability testing?
No. It is an expert review of the supplied experience. It does not replace direct research with your users and does not guarantee a commercial outcome.
What if the product needs more than five screens?
We can agree a larger review or a design and prototyping engagement before you pay. The diagnostic does not include implementation.
Can I send private access credentials?
Do not put passwords in the intake. If temporary access is necessary, we will agree on a safer handoff separately.
