- Test coverage built in
- React or Vue, matched to your product
Key Challenges We Solve
TWS adapts to where your frontend is, whether it doesn't exist yet or it's the thing slowing every release.
New Product Build
Every early frontend decision either saves you a year or costs you one.
You're not sure whether React or Vue is right for this project.
We recommend based on your team's existing skills and the product's actual complexity.
You're worried about over-engineering before you have real users.
Component architecture gets scoped to what the product needs now, with room to grow.
Performance is easy to ignore until it's already a problem.
Performance budgets get set at the start.
Accessibility feels like a nice-to-have you'll get to later.
WCAG-conscious markup and component patterns are the default.
You need a design system, not a pile of one-off components.
Shared components get built reusable from the first screen.
Scaling Products
The frontend that shipped fast now ships slowly, and nobody's sure why.
Components multiplied without a shared system, and nothing looks consistent anymore.
A real component library gets introduced and enforced, replacing the current pile of near-duplicates.
State management has become its own unsolved problem.
State gets restructured around actual data flow, not layered with another library on top of the mess.
Build and CI times have crept up until every PR is a wait.
Build configuration gets audited and fixed, since a slow pipeline is almost always a solvable configuration problem.
Performance has quietly degraded as features piled on.
Performance budgets get re-established and enforced in CI, so regressions get caught before merge.
Different teams built different corners of the UI, and it shows.
Code review and component standards get unified across the codebase.
Legacy Frontend Modernization
The frontend is old enough that every new feature costs more than it should.
An outdated framework version is now a security and hiring risk.
Migration happens incrementally, feature by feature.
There are no tests, so every change feels like a gamble.
Test coverage gets added around the areas being touched first, so refactors stop being a leap of faith.
Years of different contributors left inconsistent patterns everywhere.
Code review standards get applied going forward, with the worst inconsistencies flagged for cleanup as they're touched.
Nobody wants to touch the oldest part of the codebase.
That part gets isolated and modernized deliberately.
Hiring is harder because the stack looks dated to candidates.
Modernizing the frontend is also a hiring tool.
Our Point of View on Frontend Engineering
Five standards that apply to every engagement.
Component-driven architecture
Interfaces get built from reusable, tested components.
Test-Driven Development
Tests get written alongside the component.
Code review as a standard, not a gate
Every PR gets reviewed for maintainability.
Performance budgets
Load time and interactivity targets are set and enforced in CI.
Accessibility by default
WCAG-conscious patterns are the baseline.
Interfaces That Hold Up Under Real Traffic
Frontend engineering done right doesn't look like a clean Figma handoff. It looks like an interface that stays fast and consistent once real users, not a demo audience, start using it.
Ziva Fitness Nation, a social community, marketplace, and e-commerce platform, needed a frontend that stayed consistent and fast across a genuinely varied set of user flows: social feed, marketplace listings, and checkout, all in one product.
How Frontend Engineering Solves Real Problems
Four ways solid frontend architecture changes what your team can actually ship.
New Features Ship Without Breaking Old Ones
When a component is used consistently instead of copy-pasted with small variations, a fix or an update happens in one place instead of six.
That's the difference between a two-hour change and a two-day regression hunt.
Performance Stops Being a Rewrite Away
Performance budgets checked automatically on every pull request mean a slow component gets caught in review, not three months later in a user complaint.
That's what keeps "we'll fix performance later" from becoming "we need to rewrite the frontend."
Accessibility Stops Being a Legal Fire Drill
WCAG-conscious patterns as the default mean an accessibility audit finds far less to fix, because most of it was never built wrong in the first place.
That's the difference between a compliance scramble and a non-event.
The Codebase Doesn't Scare Off New Hires
A codebase with enforced standards and real tests is something a new hire can read and trust, instead of something they have to reverse-engineer.
That's what keeps onboarding from being its own multi-week project every time someone joins.
What Our Clients Say
I've been very impressed with how collaborative the Team Work Spirit team has been over the past year. They've always engaged as an embedded part of our team, and never as a separate entity with extra barriers to communication.

How We Work
Four steps, from design handoff to a codebase your team can maintain.
Design and architecture review
We look at the actual designs and product complexity before recommending a component structure.
Component and state planning
Shared components and state management get scoped before the first line of code.
Test-driven build
Tests get written alongside components.
Code review and performance enforcement
Every PR is checked against your standards and performance budget before merge.
