Web applications that are installable, work offline and meet the Core Web Vitals thresholds. Measured speed, a solid technical SEO foundation and an experience developed specifically for your brand.
A Progressive Web App (PWA) is an approach that turns a website from a classic page running in the browser into an application that can be installed on the home screen, opened offline and send notifications. Technically it is built on service workers, a web app manifest and modern browser APIs. Users can install it to both the desktop and the mobile home screen straight from the browser, without downloading anything from an app store; when the network weakens or drops entirely, the application remains usable.
Web performance is the measurable side of that experience. Google's Core Web Vitals metrics (LCP, INP, CLS) quantify how fast a page loads, how quickly it responds to interaction and how visually stable it is. These metrics directly affect both user experience and search engine rankings. An interface that opens slowly, responds late to clicks or jumps around while loading loses visitors within the first seconds.
This is precisely where the job cannot be solved defensibly with ready-made templates or general-purpose plugins. Real performance gains come from measurement, profiling and targeted optimisation done for your traffic profile, content structure and infrastructure. At Pan Innovation House we start PWA and performance work with measurement, pinpoint the bottleneck with data and verify changes by measuring again. One hundred per cent of the source code stays with you; API-first architecture, iterative delivery and the four-eyes review (Pan Standard) apply at every stage.
Production, warehouse, field sales and service teams often work where the internet is weak. An installable, offline-capable PWA keeps data entry going when the connection drops and syncs records once the network returns. For teams working on tablets and phones in the field, it enables fast roll-out without getting stuck in app store processes.
Carpet, machinery, textile and food manufacturers want their dealer panels, order portals and internal tools to run smoothly on mobile too. With a single PWA you deliver a consistent, fast, installable experience on both desktop and mobile, covering a wide range of devices without the cost of a separate mobile app.
On product listing, category and detail pages, every second of delay lowers conversion. A storefront that meets the Core Web Vitals thresholds, opens fast and responds instantly to interaction strengthens both user experience and organic visibility. A direct fit for companies losing rankings and sales because their current site has slowed down.
For companies serving visitors from different countries and different network conditions, speed means an equal experience. A web application that opens fast even on weak connections and stays resilient offline builds trust and accessibility across international catalogues, B2B portals and marketing sites.
We design which of your application's data gets cached, and which requests are served from the network versus the cache, according to your workflow. We choose strategies such as cache-first, network-first and stale-while-revalidate based on how critical each screen is, and deliver a meaningful offline experience.
With a web app manifest, icons, a splash screen and an installation flow, your application becomes addable to the home screen. An on-brand installation experience on desktop and mobile, with roll-out that does not wait for app store approval.
Using the Web Push protocol, we build an infrastructure that can send notifications with the user's consent. Order status, stock, campaigns or operational alerts run integrated with the backend, with permission management and targeting logic designed in.
We measure the LCP, INP and CLS metrics with field data and lab tests, then make targeted improvements to largest-content load speed, interaction latency and layout shift. We meet the thresholds through image sizing, critical CSS, code splitting and rendering strategies.
We cut page weight by shrinking the JavaScript bundle, code splitting, lazy loading, image optimisation and modern formats, a CDN and cache headers. We prune unnecessary dependencies and lighten the first load.
We make the right call between SSR, static generation (SSG) and client-side rendering for your content. Meaningful HTML structure, meta tags, structured data (schema), a sitemap and crawlability ensure search engines read your pages correctly.
With real user metrics (RUM), Lighthouse-based audits and performance budgets, we make sure the optimisation does not erode over time. Checks wired into the CI/CD pipeline verify that no release drops performance below the threshold.
We measure the current state with field data and lab tests. We chart the LCP, INP and CLS values, bundle size and network profile, and use the data to prioritise the bottlenecks causing the greatest loss. This step means starting from evidence rather than assumptions.
Based on your content and traffic profile, we set the rendering strategy (SSR/SSG/client), the caching and the offline approach. We define the PWA scope, push requirements and performance budgets together, and set measurable targets.
We implement the service worker, manifest, code splitting and optimisations piece by piece, delivering each iteration in working form. With the API-first approach, backend and frontend progress within clear boundaries; changes pass the Pan Standard four-eyes review.
We re-measure every change made and show with evidence whether it meets the target thresholds. By adding performance checks to the CI/CD pipeline, we stop later releases from eroding the gains.
We go live, keep monitoring real user metrics and provide maintenance under an SLA. When metrics approach the threshold we intervene proactively, and we keep up with browser and dependency updates.
In many scenarios, yes — especially for internal panels, dealer portals, order screens and catalogue applications. A PWA runs on both desktop and mobile from a single codebase, installs to the home screen and offers offline resilience, with no app store approval process. If store distribution or very deep device hardware access is a requirement, a native mobile app may be the better fit. We make the right call together, based on your use case.
To be realistic, we do not quote numbers before measuring. As a first step we chart your current metrics (LCP, INP, CLS, bundle size) and set achievable targets based on the data. We measure and prove the gain at every stage — not an invented figure, but real improvement measured on your own pages.
They depend on scope and become clear after a discovery call. Page count, the state of the current infrastructure, PWA and push requirements and the target metric levels determine the timeline. We first run a diagnosis and scoping exercise, then present a transparent proposal; we do not quote rough figures up front.
The source code stays one hundred per cent with you. This is an unchanging principle at Pan Innovation House. The repository, documentation and deployment configuration are handed over; your own team or another supplier can carry on if you wish. We do not build closed structures that create lock-in.
In most cases, yes. We diagnose first and assess whether the bottlenecks can be solved within the existing structure. More often than not, rendering strategy, image optimisation, code splitting and caching deliver serious gains without a rewrite. A rewrite is proposed, with its rationale, only when technical debt genuinely blocks the way.
Yes. We work API-first and integrate with your existing backend, ERP, CRM, e-commerce or payment infrastructure over standard interfaces. Push notifications, user sessions and data synchronisation are designed to work in harmony with your systems.
In a 30-minute discovery call we listen to what you need and tell you honestly whether custom development or an off-the-shelf product is the better answer.
