About me
Product design for software people use all day
I'm Adaeze Nwosu, an independent product designer. For more than a decade I've worked on B2B and fintech products where screens are dense, mistakes cost money and users are busy professionals who notice every extra click.

Services
Four ways to work together
Fixed-scope engagements with clear deliverables and a price agreed up front. Every project starts with your existing data and ends with a written handover.
Product design audit
A two-week review of one critical flow: analytics, support tickets, five user interviews and a heuristic pass. You get a ranked list of problems with evidence, effort and expected impact.
From $7,500
Embedded product design
I join your product team for three to six months, own a problem area end to end and ship with your engineers. Best for onboarding, activation, complex workflows and data-heavy screens.
From $14,000/mo
Design system foundations
Tokens, core components and documentation built with your engineers, starting from your densest screens so the system holds up where your users spend their day.
From $28,000
Accessibility review
A WCAG 2.2 AA review of your key flows with fixes your team can ship, plus usability sessions with disabled participants when you need more than a checklist.
From $9,000
Kind words

Adaeze Nwosu asked for our support tickets before asking for a brief. Two weeks later we had a ranked list of fixes, and the top three paid for the engagement within a quarter.
Elena VargaHead of Product, Orchard HRA rare designer who is as comfortable in a spreadsheet as in a usability session, often on the same afternoon. Our engineers asked to keep the decision log format.
Tobias BrandtEngineering Manager, Brindle CapitalWe hired for a pricing page and got a clearer plan structure, a simpler sales story and an honest write-up of the test that failed.
Grace MwangiCEO, SignalpostThe accessibility work was meticulous, but what I remember is how Adaeze Nwosu brought engineering along. Nobody felt audited; everyone felt taught.

Have a flow that's quietly costing you customers?
Send me the flow and the number you'd like to move. I'll reply with how I'd approach it, what I'd look at first and what it would cost.
