Application — UI/UX Designer · Mango

Mango, I want to be
your designer.

Fifteen years of SaaS and product design, mostly embedded with engineering-led teams. I design close to the medium, communicate in the language developers speak, and deliver work that actually ships.

Selected Work

SaaS UI,
end to end.

Flows, layouts, interaction details — iterated until they’re right, in close collaboration with the engineers building them. Four projects that show how I work.

Consumer SaaS · Subscription App
250% increase in paid trial starts
Situation

Strong product, strong retention — but users were dropping before reaching the core value. Top of funnel was leaking.

What I did

Ran user interviews to find the drop-off. Rebuilt onboarding from scratch. Shipped a design system so every iteration after moved faster.

Result

Paid trial starts up 250%. Team left with a repeatable process and a system they could extend without me.

B2B SaaS · Employee Wellness
$85K → $120K ARR in 6 months
Situation

Engineering-led founders with no design process. Strong vision, no execution path. Needed a product perspective embedded from day one.

What I did

Rebuilt the dashboard, built the design system, ran user interviews to validate the roadmap before a line of code was written.

Result

41% ARR growth in 6 months. Founders built product instincts that outlasted the engagement. Company entered acquisition talks.

Consumer + B2B SaaS · Subscription Platform
2M+ users across consumer and enterprise
Situation

Successful consumer app expanding into B2B enterprise. Two very different user types. One product surface to serve them both.

What I did

Designed a workspace and permission layer on top of the existing product. Consolidated three design systems into one responsive system spanning mobile, tablet, and desktop.

Result

2M+ total users. $1.2M enterprise ARR in year one. Three fragmented systems became one — the team shipped twice as fast after.

SaaS · HR & Recruiting
Complex workflow, designed to feel simple
Situation

HR teams managing candidate pipelines in spreadsheets and email. The workflow was genuinely complex — the interface couldn’t be.

What I did

Designed end-to-end: campaign wizard, CRM view, smart search and filtering, live metrics dashboard. Iterated in the browser from rough to polished, in close collaboration with engineers.

Result

A production SaaS interface HR teams can navigate without training. Shipped iteratively through tight cycles with direct engineer collaboration throughout.

How I work

Taste, clarity,
and iteration.

The things Mango mentioned are the things I care most about.

01

Engineers are collaborators, not customers

I’ve shipped code. I know what “too complex to build” looks like before an engineer has to say it. I work alongside dev teams — not ahead of them — and my handoffs actually build.

02

Iterate, don’t reveal

I don’t disappear for two weeks. I share early, share rough, and get feedback before investing in polish. Small loops, fast cycles.

03

I think in systems

Every screen considers what comes before and after it. I’m not solving for the current state — I’m building patterns that hold up as the product scales.

04

Direct feedback is a feature

Tell me what’s wrong. I won’t take it personally. Candid, specific feedback is how good work gets made — the faster it comes, the better.

About

15 years of design.
No agency. Just me.

I’m Joshua Wold. I’ve spent 15 years doing product design across consumer apps, B2B SaaS, mobile, and e-commerce — almost always as the sole designer embedded inside an engineering-first team. That’s the environment I do my best work in, and it’s exactly what Mango is describing.

I’m not an agency. There’s no account manager between us. I move fast, speak developer, and I genuinely enjoy refining interfaces over long engagements rather than handing off and walking away. The work getting better with each iteration is the whole point.

I live in Post Falls, Idaho. I write novels, run trails, and spend probably too much time thinking about why some interfaces feel obvious and others don’t.
