The proof
How we structure a production React.js project.
LAYER 1
Architecture
Clear module boundaries. Typed contracts. No circular dependencies. Easy to onboard new engineers in a week, not a month.
LAYER 2
Testing
Unit for logic, integration for boundaries, E2E for critical flows. 80%+ coverage on money-handling paths.
LAYER 3
Observability
Structured logs, traces, metrics. Every deploy has an alarm trail. Every 3AM incident has a trail back to root cause.
What we build
Where we deploy React.js.
01
Greenfield products
v1 through to first scale.
02
Team augmentation
Senior engineers embedded with yours.
03
Legacy modernisation
Strangler-fig migration to React.js.
04
Code review & audit
Independent technical audit for investors or acquirers.
ClientA funded SaaSSaaS
Built a React app running at <em>2M+ page views/day</em> with 40ms interaction latency.
A React.js project where architecture decisions made in week one held up under 100× scale. No rewrite. No regrets.

What it's like working with us
Three React.js agencies told us the job would take 9 months. Ligio shipped in 14 weeks. Better code than the last two hires.

Questions
Answers, without the fluff.
Still have questions? Talk to us — we answer within a business day.
05common questions
01Which state manager?
TanStack Query for server state, Zustand or React Context for client state. Redux only when legacy code requires it.
02How long does a typical engagement take?
Most projects run 10-18 weeks from kickoff to production launch. We share a milestone plan in week one and update weekly.
03Do you sign an NDA?
Yes. Standard mutual NDA on request, before the first technical conversation.
04Who owns the code and IP?
You do. Code is in your GitHub org from day one. All IP transfers unambiguously on delivery.
05What does your pricing model look like?
For v1 builds: fixed scope, fixed milestones. For ongoing work: monthly retainer with a defined team. We don't do time-and-material surprise billing.
