How do web and mobile apps share one backend?

One API and shared domain models serve web and mobile clients. Auth, validation, and business rules live on the server so platforms do not diverge. UI can differ by device. Product behavior stays consistent. That is the default unless a platform-only constraint forces a split.

How long to launch on web and mobile?

Web-only MVPs often take 8-16 weeks. Dual web and mobile with shared APIs often take 4-7 months to a public store release, depending on design readiness and third-party reviews.

Can you update our existing React or mobile app?

Yes. The repo, dependencies, and release pipeline get audited first, then features, performance work, or a staged redesign take over.

Do you handle App Store and Play Store submission?

Yes. Builds, privacy labels, and review responses get prepared. You keep the developer accounts; work happens inside them under your access rules.

Do you work with US and UK startups and enterprises?

Yes. Overlap hours and async documentation are part of how remote delivery runs for North American, UK, and Middle East clients.

Is SaaS product development included?

Yes. Multi-tenant SaaS web apps, billing integration, admin tools, and customer dashboards are a core part of web and mobile work.

Yes. NDAs are routine before product roadmaps, analytics, or private repos get shared.

Web & Mobile Development

Web and mobile apps with React, Next.js, Flutter, and React Native

Web apps and mobile clients built for daily use. React and Next.js on the web, Flutter or React Native on phones, with shared APIs that hold a SaaS or consumer product together.

Step 1

Product and platform choices

Lock target platforms, must-have flows, and shared API needs so web and mobile do not diverge by accident.

Step 2

Design system and foundations

Components, navigation, auth, and CI for each client land first, with a staging build you can click through.

Step 3

Feature sprints to launch

Ship user-facing flows in priority order, with QA on real devices and browsers before each release train.

Step 4

Store release and iterate

App store submission, monitoring, and a backlog for the next version based on crash data and user feedback.

When web and mobile apps need the same product team

Web and mobile development matter when customers or staff must complete real work in a browser or on a phone: checkout, booking, dispatch, learning, collaboration, or account management. Performance, offline quirks, store review, and accessibility stop being optional once people live in the app. A pretty mock fails if the list scrolls like mud or the form loses state on a flaky connection.

SaaS web apps are a common shape. Multi-tenant auth, billing hooks, admin consoles, and customer-facing dashboards need one design system. Consumer apps add feeds, maps, media, and push notifications. Internal tools prioritize speed of ops over marketing polish. One team that can share models and APIs across web and mobile beats two vendors arguing about whose bug it is.

Help covers starting fresh, extending a React or React Native codebase, or adding a Flutter client beside an existing web product. Platform choice is a product decision. Trade-offs get explained before locking them so you are not stuck with a stack your team cannot hire for.

What we build

On the web, application UI with React and Next.js, server rendering where SEO or first load matters, and solid API clients. Marketing sites only when they sit next to the product. On mobile, Flutter or React Native for shared codebases, or native modules when a feature demands them. Store builds, crash reporting, and analytics land before public launch. If a feature needs background sync or deep links, that gets planned with the first release, not bolted on after store rejection.

Typical products include marketplaces, rental and commerce flows, social discovery, assessment platforms, fleet and field tools, and B2B SaaS with role-based access. Admin and support surfaces your team uses after launch get built too. Gusto-style discovery, QuizQuest-style learning, and Loom & Luxe-style browse and checkout are the kind of concrete UI that ships here, not wireframe theater.

For SaaS specifically, planning covers shared component libraries, tenant-aware routing, and environments that let you demo a feature to one customer before opening it to everyone. Billing, entitlements, and audit logs get treated as product features, not bolted on the week before launch.

How we deliver

Platforms get locked early: web only, mobile only, or both with a shared backend. Design and engineering work from the same component language so mobile does not become a late translation of a desktop mock. Releases go through TestFlight, Play internal tracks, and web staging.

Clickable progress shows up on a cadence you can plan around. QA runs on real devices and browsers. Store metadata, privacy labels, and review responses get prepared with you keeping the developer accounts. If a third-party SDK or store policy blocks a path, that surfaces early and the plan changes instead of waiting until submission day. Release notes stay short and honest so support knows what changed before customers ask.

Stack and practices

React, Next.js, TypeScript, Flutter, and React Native cover most front ends. Back ends often use Node, Django, Rails, or Express on AWS with Postgres and object storage. Maps, payments, and messaging plug in through proven vendors such as Stripe and Google Maps.

Bundle size, cold start, list virtualization, and image pipelines get attention because those details decide whether users stay. Accessibility and keyboard flows get tested. CI runs on every pull request. Observability with tools like Sentry is part of launch, not a later nice-to-have.

SaaS web and mobile products

SaaS products usually need a customer app and an admin app that share one API and one design system. Multi-tenant auth, billing hooks, entitlements, and audit logs belong in the first architecture, not in a scramble before launch.

Feature flags and tenant-aware routing let you demo a change to one account before everyone sees it. Mobile clients for the same SaaS stay on the same models so field and desk users do not get two different truths. QuizQuest-style assessment and RelayHub-style ops tools are the kinds of SaaS surfaces this stack is built for.

Industries we support

E-commerce and rentals, hospitality and local discovery, logistics, edtech, and B2B SaaS show up often. Users on phones in the field or on laptops in an office both have patterns that fit. The shared API stays honest so the clients do not drift apart.

E-commerce

Loom & Luxe

Loom & Luxe: rent the dress, skip the full retail bill

Rentals, deposits, and return logistics

Loom & Luxe makes designer dresses reachable for short events. Shoppers browse an editorial catalog, book a rental window, pay a fraction of retail, and get pickup handled when the window closes. Owners and brands need inventory, active rentals, and earnings in one lender dashboard instead of side chats and spreadsheets. The business needed rental commerce that feels like shopping, not a form dump. Deposits, delivery addresses, and returns had to be productized. If those steps stay manual, the marketplace cannot grow past a handful of garments and a very patient ops person. Trust sits at the center. Renters need deposits and holds that feel fair. Lenders need payouts and inventory status they can verify. Both sides had to feel comfortable putting real garments and real event dates into the system, not treating it like a weekend experiment. The storefront had to feel like fashion retail while the backend behaved like a logistics system. Pretty pages without return automation fail. Automation without an editorial catalog fails too. That tension is the real product.

EdTech

QuizQuest

QuizQuest: practice that shows what you actually mastered

Timed quizzes + admin question creator

QuizQuest gives students timed practice with instant feedback and shows which topics they own versus which ones keep failing them. Instructors need a Question Creator that drafts and publishes assessments without another spreadsheet war or PDF email chain. The goal was assessment that teaches during the attempt, not only after a graded dump. Profiles should reflect mastery over time so learners and teachers can plan the next practice set from real attempt data, not from memory of last week's quiz. Schools and training programs wanted practice that survives real class periods. Timers have to hold up. Feedback has to arrive while the question is still fresh. Authoring tools have to be ones instructors will open twice a week. QuizQuest was built for that weekly rhythm, not for a one-off demo quiz. Instructors also needed confidence that a published quiz would look the same for every student in the room. That sounds basic until you mix diagrams, timers, and late joiners. Consistency was part of the promise.

Hospitality

Gusto

Gusto: find food through friends, not empty star dumps

Maps, feed, and restaurant profiles

Gusto helps people find places worth eating through maps, friends, and dish photos, without another generic ratings wall. Star averages hide whether a place fits your crowd. Discovery should be shaped by taste and people you follow, with a map you can browse and photos that show the plate. That means a social loop that still feels fast on mobile: posts, reviews, notifications, and profiles that stay useful when you are already standing on a sidewalk deciding where to walk next. Web sits alongside for browsing, but the core experience is built for phones in the wild. Hospitality discovery fails when every place looks the same on a star list. Gusto bets on social proof you can inspect: who posted, what the plate looked like, and where it sits on the map. The product should feel useful while you are already outside, not only when you are planning from a desk. Friends and photos are the ranking signal the product wants to earn. Maps provide place and distance. Together they answer "where should we eat" with more than a cold average score.
