How we build

Typical first reply · within 1 business day · English & Vietnamese

You get a scoped path

Rough timeline, risks, next step — no endless sales deck.

Engineers read your brief

Senior people lead discovery, not a rotating call-centre roster.

Code you can inherit

Documentation, handover, sensible defaults — your team owns the stack.

If software is slowing you down, we fix the right layer

Most founders do not need more tickets — they need a partner who ships the product experience customers feel, and the reliability your team stops firefighting.

Our app feels slow or breaks on bad networks.

Scarlet: Performance budgets, resilient data fetching, and UX that fails clearly — not silently.

Every new feature takes forever and feels fragile.

Scarlet: Clear architecture, typed boundaries, and reviews that keep complexity visible.

We outsourced once and got unmaintainable code.

Scarlet: You get readable TypeScript, docs, and a handover your devs can own.

We are not sure what to build first.

Scarlet: We help you sequence scope so the first release proves value — then we scale.

Why teams choose Scarlet over a generic agency or loose freelancers

Product mindset

We care about onboarding, retention, and support — not only closing the sprint.

Senior execution

Hands-on builders with production scars: auth, billing, realtime, integrations.

Straight communication

Weekly visibility, blunt trade-offs early, documentation you can reuse.

Delivery system

Built like a serious product team — optimized for speed and reliability

The homepage now uses lightweight interface visuals instead of always-on WebGL. That keeps the brand polished while reducing JavaScript, GPU work, and interaction lag on real devices.

Elastic infrastructure

Distributed frontends without chaos

From edge-ready SSR to fault-tolerant client hydration, we engineer surfaces that degrade gracefully when networks and APIs misbehave — so your users keep working when the real world gets messy.

Edge + regional routing awareness
Resilient data layers with stale-while-revalidate
Back-pressure friendly streaming UX

We do our best work when this sounds like you

No pressure — if the fit is not mutual, we will tell you quickly and suggest alternatives.

You are building or scaling a serious web product — dashboards, portals, SaaS, or internal tools.
You care about polish and reliability — not shipping a brittle prototype disguised as v1.
You want a partner who proposes trade-offs honestly instead of disappearing after invoicing.
You value TypeScript-era engineering: tests where they matter, ops that do not crumble at launch.

Check if your project fits

What you walk away with

Whether we build the whole roadmap or unblock one critical release, engagements are designed so you can keep momentum after we step back.

Request a tailored quote

Source code in your repository, sensible Git history.
Environment and deploy notes aligned with how you operate.
Accessible UI foundations and sensible performance defaults.
Security hygiene: dependency updates, secrets never in client bundles.
Optional augment: we stay on for releases and spikes.

Questions we hear before kickoff

We are not technical — can we still work with you?: Yes. Bring goals and pains; we translate them into phased software work and plain-language updates.
How fast can you start?: After a short brief and call, we align on a start window. Many projects begin within one to three weeks once scope is clear.
Fixed price or retainer?: We match the model to risk: phased fixed scopes for milestones, retainers when you need ongoing velocity and advice.
Can you work with our existing team?: Often. We integrate with your PM and designers, or pair with your engineers on hard parts — whatever ships the product fastest.

Ready to talk about your software — without committing to anything yet?

Send your brief or a few bullet points about your users and deadlines. If we are not the right fit, we will say so honestly and point you elsewhere.
