UI/UX Design
UI/UX design agency in the USA. User research, clickable prototypes, design systems and WCAG 2.2 AA accessibility, tested with real users first.
HandsOnTech is a U.S. UI/UX design studio that maps the user journey, prototypes it in Figma and tests it with at least five real users before development starts, so a redesign is decided by evidence, not opinion, and you don't pay for the same interface twice.
Design decided by evidence, not opinion
Most redesigns are a coin flip. Someone senior likes a direction, the team builds it, and six months later the metrics are flat, so you pay for redesign number two. The fix isn’t better taste. It’s evidence, gathered before code exists, when changing course costs hours instead of sprints.
That’s the entire logic of our design process: map the journey, prototype it, put it in front of five real users, and let their behavior (not the loudest voice in the room) decide what ships.
What evidence-first design looks like
- Research, interviews with real users, analytics review, and journey mapping to find where intent currently dies
- Wireframes, low-fidelity structure first, so debates are about flow and logic, not button colors
- Clickable prototype, a Figma prototype that feels real enough to test honestly
- Usability testing, five or more users attempting your core tasks while we watch, measure and take notes
- Visual design & system, the tested skeleton gets its skin: typography, color, motion and a component library
- Developer handoff, tokens, specs and annotated files, or a straight-line continuation into our own build team
Five users may sound small. It reliably surfaces the majority of usability problems, and it’s the difference between finding them in a $500 test session versus a $50,000 rebuild.
Accessibility is a design decision, not a compliance chore
We build WCAG 2.2 AA into flows from the first wireframe: contrast, focus order, touch targets, error recovery, plain language. Retrofitting accessibility after launch costs multiples more and usually shows.
It also pays commercially, and the mechanism is not mysterious. The work that makes a page usable with a screen reader (real heading structure, meaningful link text, plain language instead of jargon, forms with labels that survive autofill) is the same work that makes the page legible to a crawler, quotable by an AI answer engine, and readable by a stressed parent on a phone in a hospital corridor. Accessibility remediation and conversion work are largely the same edits ordered differently.
Design systems: the gift that keeps shipping
The prototype proves the direction; the design system makes it durable. We deliver component libraries in Figma with tokens for color, type and spacing that map one-to-one to code. The payoff compounds: feature two ships faster than feature one, new hires stop reinventing buttons, and your product looks like one product instead of five eras of opinions.
If your product has AI features (streaming output, confidence states, citations) that’s a specialized pattern language of its own. See our AI UI/UX design practice.
Where to start
If you have a live product, start with the UX audit: two weeks, a recorded walkthrough of where users struggle, and a prioritized fix list. If you’re starting fresh, book a scoping call, you’ll leave with a plan, a price and a date, and the research starts the week you sign.
Why most redesigns fail
Opinion-driven UI costs twice, once for the wrong design, again to fix what users refuse to adopt.
Stakeholder opinions win
Boardroom taste replaces user evidence. Launch day looks polished; week two shows drop-off nobody predicted.
Handoff breaks the intent
Figma files arrive without edge cases, states or accessibility notes. Engineering improvises, and your brand pays for it.
No baseline metric
Without a number to move (signups, completion, time-to-task) you cannot tell if the redesign worked.
What we design and deliver
Research-backed UX that engineers can build without guesswork.
User research & journeys
Interviews, session review and journey maps tied to the one metric this release must move.

- Code, designs and content transfer on final payment
Growth Retainer
Monthly compounding work on organic and paid visibility, reported against pipeline.
- Monthly sprint plan agreed in advance
- Live dashboard, the same numbers we see
- AI visibility report: which prompts name you
- No long lock-in, cancel with 30 days notice
- Same team as your build, no handoff loss
Dedicated Team
Senior specialists embedded in your Slack, repo and standups, capacity without recruiting.
- Start within 1–2 weeks of the intro call
- Your tools, your process, your time zone
- Scale seats up or down with two weeks notice
- NDA and full IP assignment from day one
- Direct access, no account-manager relay

What you can hold us to
Not adjectives, terms. Each of these is written into the engagement before you sign.
Fixed price, in writing, before work starts
You receive a written scope with milestones, deliverables and a delivery date within 48 hours of the free audit. No hourly creep, and no change order three weeks before launch.
You own everything on final payment
Source code, Figma files, content and analytics access transfer to you when the final invoice clears. No license fees, no vendor lock-in, and no platform you can only edit by paying us.
A 30-day bug warranty, in the contract
Bugs found in the first month after go-live are fixed free. It is a contractual term rather than a sales promise, and it is the reason we would rather ship correctly than ship early.
Who hires us for UI/UX
SaaS founders rebuilding onboarding
Marketing teams with low landing-page conversion
Product leads inheriting legacy UX debt
Enterprises needing WCAG 2.2 AA conformance
30-day warranty

How much does UI/UX design cost?
A UX audit starts around $5k. A full product design engagement (research, prototype, testing and design system) typically runs $15k to $60k depending on screen count and complexity. Fixed quote in writing after a free scoping call.
How long does a UX design project take?
A UX audit takes about two weeks. A complete design cycle, research, wireframes, prototype, two rounds of usability testing and handoff-ready specs, typically takes 4–8 weeks. Design-plus-build engagements overlap phases so total time to launch stays shorter.
What does usability testing actually involve?
We put a clickable prototype in front of at least five real users from your audience and watch them attempt core tasks, signing up, booking, buying. We measure completion and time-on-task, then fix what tripped them. Five users typically catch about 85% of the usability problems, before those problems are expensive.
Do you only design, or also build?
Both. Many clients hire us for design and development together so nothing is lost in handoff, the engineers who'll build it review feasibility during design. We also take design-only engagements and deliver developer-ready Figma files, tokens and specs to your in-house team.
What is a design system and do I need one?
A design system is a library of reusable components, tokens and rules that keeps every screen consistent and makes new features dramatically faster to design and build. You need one once your product has more than a handful of screens or more than one person shipping UI.
Can you audit our existing product's UX?
Yes. A UX audit covers your key flows, conversion friction, accessibility gaps and quick wins, delivered as a recorded walkthrough plus a prioritized fix list your team can act on with or without us.
