Who You Work with on Your Software Project

CTOs, engineering managers and product leads in Seattle, many working beside large in-house teams, make up most of our conversations. We fit around your engineers instead of asking them to fit around us.

A Lead You Can Call

One named lead takes responsibility for delivery and answers when you call. Behind them sit React engineers, back-end developers, designers and testers, which gives the team room to stretch when a launch crowds the calendar.

Short, Regular Updates

Our calls run on video, with in-person meetings when arranged, and stay inside Pacific time hours. After each one, a written note lists decisions made, work shipped and anything holding us up.

Inside Your Engineering Process

We follow your branching, review and release habits, and we work with your designers, product owner and any supplier already on the code. Documentation is written for the next developer to read.

ReactJS Applications We Build for Seattle Industries

Seattle is a Tier 1 city for tech talent, and it also runs on trade, aerospace, life sciences and tourism. Each calls for a different kind of React interface.

Technology and Software

How we help
Customer dashboards, admin consoles and subscription and billing screens.
Plan for
Reusable components and frequent releases

Maritime Trade and Logistics

How we help
Shipment tracking portals, booking screens and partner status boards.
Plan for
Live data from carriers and terminal systems

Aerospace and Manufacturing

How we help
Supplier portals, parts traceability views and production planning screens.
Plan for
Long records, filters and strict document control

Life Sciences and Global Health

How we help
Research data explorers, collaboration portals and reporting views.
Plan for
Separated access for each partner organization

Green Economy

How we help
Energy monitoring dashboards and project tracking tools.
Plan for
Sensor feeds and charts that stay readable

Tourism, Cruise and Events

How we help
Booking flows, itinerary builders and event pages.
Plan for
Seasonal demand and phone-first screens
Which privacy laws and industry rules apply to you is for your legal team to decide. We build the product so they can review how it handles data.

Build, Buy or Modernize? A Plain-English Guide

React isn’t always the answer. Your product, team and timeline decide, and this is how we weigh the four routes with clients.
Route

React Single-Page App

ReactJS development
Pick it when
You need a rich, app-like interface for signed-in users, such as a dashboard or portal.
Trade-off
Public pages need extra work to load fast and be found in search.
Route

Server-Rendered React

Full-stack development
Pick it when
Public pages must load quickly and be easy for search engines to read.
Trade-off
More moving parts on the server to host and maintain.
Route

Angular

Angular development
Pick it when
Your team already knows it, or you want a strict, all-in-one framework.
Trade-off
A heavier learning curve if your engineers come from React.
Route

React Native

Mobile app development
Pick it when
You want an iOS and Android app that shares skills and logic with your React team.
Trade-off
Certain hardware features call for native code.
Not sure which fits? A short discovery session usually settles it before any code is written.
Custom Software Development
Software Consulting
Application Modernization
Application Integration

Security and Quality Checks Built Into Every Build

NIST’s Secure Software Development Framework guides how we work. On daily tasks it translates into the habits listed here.

What Shapes the Cost of Custom Software

We keep prices off this page, because a React product can be one dashboard or a full platform. Six factors move the effort most, and a call settles each.

Interface Scope

↑ Costs more when
many screens, roles and complex tables or charts are needed
↓ Costs less when
a few focused screens form the first release

Design System

↑ Costs more when
a full component library with custom branding is wanted
↓ Costs less when
an existing component set can be tailored

API and Back End

↑ Costs more when
a new Node.js back end and database must be designed
↓ Costs less when
documented APIs already exist

Performance

↑ Costs more when
large data sets, live updates and strict load times apply
↓ Costs less when
data volumes and traffic are modest

Security and Compliance

↑ Costs more when
sensitive records and audit trails are involved
↓ Costs less when
the app is staff-only and holds little sensitive data

Support After Launch

↑ Costs more when
round-the-clock cover is required
↓ Costs less when
weekday support meets your needs

Hire Software Developers

Pick the model by stage. A startup’s first release often suits a fixed price build, a team needing extra hands may want dedicated developers, and a company reworking an old interface often begins on time and material.

Fixed Price Build

We settle the scope, milestones and cost before work begins. A good match when the brief is clear and the MVP budget is fixed.
Suits

Time and Material

Payment tracks hours worked, with priorities reshuffled at the start of each sprint. Fits products that evolve as users respond.
Suits

Dedicated Developers

React developers, QA and a designer if needed, working in your sprints and reviews.

Teams that need added capacity

How to Choose a Software Development Company

Many proposals look alike. These seven questions show how a React team works from one day to the next.
01

Which Engineers Will Write the React Code?

Listen for
Named developers and their roles, not a general promise about the team.
02

What If a Past Supplier Left the Front End Half Finished?

Listen for
A code audit first, then advice on what to keep, fix or rebuild.
03

Can You Work with Our CTO and In-House Engineers?

Listen for
Yes. You get a place in your stand-ups, tools and code reviews.
04

How Are Scope Changes Handled?

Listen for
A written process that lays out the time and cost impact before any change is approved.
05

Who Owns the Code and Designs?

Listen for
The code and designs are yours, and the contract spells that out clearly.
06

How Do You Test and Release?

Listen for
Automatic tests, a staging site for sign-off and a rollback path for each release.
07

Will You Say When React Is the Wrong Tool?

Listen for
Yes. Angular, server-rendered pages and a plain website are weighed fairly.

How We Run a Software Project

Our process has six stages, and every one closes with a reviewable deliverable. Complexity sets the timing.
01

Discovery

About a week of workshops that clarify who uses the product and what constrains it.
02

Scoping and Architecture

Typically one to two weeks, ending with a written scope, a chosen technical approach and your quote.
03

Design and Prototype

Around two weeks of screen design, ending in a prototype people can click through.
04

Sprint Builds

Work runs in short cycles, each ending with the running software on show.
05

Evaluation and QA

A testing phase of around four weeks that exercises features, response times, safeguards and ease of use.
06

Launch and Iterate

We release, watch how it performs live and plan the next round with you.
Each stage ends with something you can review.

The Villas Mooloolaba

Hospitality / Boutique Vacation Rental
The Villas Mooloolaba does the hard part well – four unique two-bedroom villas around a shared pool on Queensland’s Sunshine Coast. The website wasn’t carrying its weight: competing against hotel chains and OTA listings meant direct booking had to feel just as easy, and guests couldn’t easily compare all four villas.

eCommerce / Fashion & Apparel
Kayme does the hard part well – designing dresses people genuinely want, with a loyal following built over time. The backend wasn’t carrying its weight: Magento couldn’t scale without inviting fresh problems, and orders had to be manually reformatted for the shipping company by hand, every single time.
