Our Journey

Step 1

Discovery & Strategy

We align on users, integrations, and success metrics so the roadmap matches what your web product actually needs to prove.

Step 2

UI/UX Design

We design flows and components for the browser — accessible, responsive, and consistent with your brand.

Step 3

Development

We build the frontend and APIs with code review and CI so features ship predictably and stay maintainable.

Step 4

Testing & QA Assurance

We test across browsers, viewports, and roles so releases are stable before they hit production.

Step 5

Deployment

We ship to your cloud with staging, rollbacks, and monitoring — no app-store submission step, because this is a web platform.

Step 6

Support & Evolution

We stay on for fixes, performance, and new releases as traffic and features grow.

Why us?

We design around user journeys and business metrics for your web product, not a generic ticket queue.

React, Node, and cloud choices matched to your team and hosting — not a one-size template.

Built to operate

Auth, logging, backups, and CI so the app is runnable after we hand it over, not just demoable.

One squad, web to API

We get asked these a lot. If yours isn't here, reach out — we respond to every inquiry within 24 hours.

Ask Us Anything

How much does a custom web app cost?

SaaS platforms, portals, and dashboards we build typically fall between $20k and $200k. A focused first release is often at the lower end. You get a fixed-scope quote after a free call.

How long does web app development take?

A production-shaped first release is often 6–10 weeks. Larger SaaS products with roles, billing, and integrations take 3–6 months, shipped in two-week increments.

Which stack do you use?

Frontend is typically React, Next.js, Angular, Vue, and TypeScript. Backend is Node.js, Python, or .NET. Data on PostgreSQL, MongoDB, or Redis, hosted on AWS, Azure, or GCP — matched to your team and hosting.

Who owns the source code and IP?

You do. Source code, design files, and all project IP transfer to you on final payment. No licensing fees and no lock-in on the work we deliver.

Do you sign an NDA before we talk details?

Yes. We sign a mutual NDA before any product specifics are shared. Across our production work we have had zero confidentiality breaches.

What happens after launch?

We offer a retainer for monitoring, bug fixes, and the next set of features. Most clients stay on 10–40 hours a month for the first year. We do not advertise 24/7 coverage — support is extended US-hours.
