Web Development
Progressive Web App Development (PWA)
We build PWAs that feel like real apps: fast loads, installable UX, offline support, and a data strategy that behaves well on unstable networks.
Overview
What this service is
This service delivers a Progressive Web App that can be installed on devices and stays usable even when connectivity is limited—ideal for mobile-first products and field workflows.
We design caching and data sync strategies around your real user journeys so “offline” means predictable behaviour instead of confusing errors.
You get a production-ready build with Lighthouse-friendly performance work, plus handoff notes that explain how offline and sync logic is structured.
Benefits
What you get
App-like UX without app stores
Installable experience with fast navigation and device-friendly interaction patterns.
Offline and poor-network resilience
Core workflows stay usable when the network is unreliable or unavailable.
Faster performance on mobile
Caching and bundle discipline reduce load time and improve responsiveness.
Lower delivery and maintenance cost
One web codebase instead of separate native apps for many use cases.
Push-ready foundations (optional)
Prepare the architecture for notifications where business needs justify it.
Clear monitoring and handoff
You receive source code and guidance to maintain offline logic safely.
Features
What we deliver
Service worker + caching strategy
Workbox/service worker setup tailored to your assets and routes with safe cache invalidation rules.
Offline-first data patterns
Local storage/IndexedDB strategies that keep workflows usable and consistent.
Installable UX + app shell
Install prompts, icons, and app shell behaviour so the PWA feels native-like on devices.
Sync + conflict handling (when needed)
Background sync patterns and pragmatic conflict resolution for offline edits and updates.
Performance pass
Lighthouse improvements, image strategy, and bundle optimisation to keep the PWA responsive.
Deployment + rollout notes
Release guidance and documentation for caching rules so updates don’t confuse users.
Process
How we work
Discovery
We identify offline-critical journeys and define what must work without a network.
Caching + data strategy
We design cache rules, sync behaviour, and update flows to avoid stale-content surprises.
Build
We implement PWA features and user flows in milestones with demos and test scenarios.
QA
We test offline, low-network, and update scenarios across devices to validate behaviour.
Launch
We ship rollout notes and monitoring hooks to catch cache issues early in production.

Use Cases
Who this is for
Field-team workflows
Offline data capture and sync for technicians, surveys, inspections, and on-site tasks.
Education and training apps
Lesson access and progress flows designed for intermittent connectivity.
Event or ticketing experiences
Fast navigation and scan-ready UIs that work in venues with poor networks.
Lightweight commerce journeys
Fast product discovery and cart flows when a full native app isn’t necessary.
Internal tools on shared devices
Installable, secure web apps used across teams with predictable performance.
FAQ
Frequently asked questions
Yes. Support differs slightly by platform, but installable behaviour and offline patterns work well when designed with those constraints in mind.
Sometimes. Push support depends on platform capabilities and your use case. We can design the architecture to be push-ready even if rollout is phased.
We implement safe cache invalidation rules and clear update behaviour so users get new versions reliably without confusing mismatches.
Yes. We can implement offline edits with background sync and conflict-handling patterns based on your data rules.
Yes. We focus on real performance metrics and keep bundles, images, and caching aligned to conversion journeys.

Delivery considerations for your region
Compliance & Data (EU)
For Germany/EU delivery, we keep GDPR-first patterns: data minimisation, purpose-limited storage, and explicit access boundaries.
We can work under a DPA (template available on request) and implement pragmatic retention/deletion flows when needed.
- GDPR-first architecture patterns (generic, no legal claims)
- DPA template available on request
- Retention/deletion and export flows where required
- Least-privilege access and safe logging defaults
- Documented data flows and access boundaries
Timezone & Collaboration (EU)
We align to EU working hours with CET-friendly collaboration windows and async progress updates.
We keep delivery predictable: weekly milestones, documented decisions, and clear scope control.
- EU overlap with CET-friendly windows
- Async-first delivery with written decisions
- Weekly milestone demos and progress checkpoints
- Clear change control to avoid surprises
- Escalation path for blockers and risks
Engagement & Procurement (EU)
We support procurement-friendly engagements with clear scopes, milestone plans, and documentation that stakeholders can review.
For EU teams, we can structure invoices and milestones for EUR-based engagements where appropriate.
- EUR-based engagements and invoicing options
- Discovery-first option to reduce delivery risk
- Milestone-based billing and scope sign-offs
- Vendor onboarding documentation on request
- Transparent change control and approvals
Security & Quality (EU)
We prioritise reliability: reviewable PRs, predictable releases, and tests that protect critical paths.
Performance budgets and clear release discipline keep the product stable as it grows.
- CI-friendly testing: unit + integration + smoke tests
- Performance budgets + bundle checks
- Release checklist + rollback-safe deployments
- Security checklist for auth and sensitive data flows
- Observability hooks (logs + error tracking) ready for production
