Why Most Web Apps Feel Like They're From 2015
Slow pages, unclear flows, and brittle code make a web product expensive to change. We improve the experience and the underlying system together, whether the result is a PWA, a server-rendered app, or something simpler.
Where the work helps
01
Progressive Web Apps (PWAs) That Feel Native
A PWA can bring offline support, push notifications, and an installable experience to a web product when those features fit the audience.
The Benefit: One distribution path with app-like capabilities.
The Result: Users can return to the product without waiting for an app-store download.
02
Modern Frontend Engineering (React, Next.js, Vue)
We build SPAs and server-rendered applications with React, Next.js, Vue.js, and TypeScript. The choice follows the content, interaction, and performance needs.
The Benefit: A faster interface with less JavaScript in the browser.
The Result: Better page performance and a clearer path for search and accessibility work.
03
Scalable Backend Architectures (Node.js, Python, Java)
We build backends with Node.js, Python/Django, Java/Spring, or .NET Core and choose the data layer and API style around the workload.
The Benefit: A service boundary the team can test and monitor.
The Result: You can add capacity without rewriting the product every time usage changes.
04
Cloud-Native & Serverless Deployment
We deploy on AWS, Azure, or Google Cloud with the simplest hosting model that fits the workload, from managed services to containers and serverless functions.
The Benefit: A clearer trade-off between control, resilience, and cost.
The Result: The product has a plan for normal traffic and an explicit response to a spike.
05
API-First & Headless CMS Integration
We connect headless CMSs such as Contentful, Sanity, or Strapi when your content team needs to work without a code release. API-first boundaries can also serve more than one client.
The Benefit: Content changes follow the publishing workflow rather than a development sprint.
The Result: The team gets a shared source for content without coupling every screen to it.
06
Conversion-Optimized UX/UI Design
We work through user flows, forms, content, and calls to action with the actual task in mind. Where the traffic supports it, we test the changes rather than guessing.
The Benefit: Fewer avoidable steps in the workflow.
The Result: A product that makes the next action easier to understand.

How the work runs
Discovery, Strategy & Architecture
We map the user flows, define technical requirements, and architect the solution. The stack, hosting, and scaling plan follow the product's actual constraints.
UI/UX Design & Prototyping
Wireframes, high-fidelity mockups, and interactive prototypes. We validate designs with user testing and stakeholder feedback before writing a single line of code.
Full-Stack Development (Agile Sprints)
Build frontend (React/Next.js/Vue) and backend (Node.js/Python/Java) in parallel. Weekly demos, continuous integration, and automated testing ensure quality at velocity.
Testing, QA & Security Audits
Automated unit/integration tests, manual QA across browsers/devices, load testing, and penetration testing. We find and fix bugs before your users do.
Launch, Monitor & Optimize
Deploy to production with zero-downtime strategies (blue/green, canary). Set up monitoring (uptime, performance, errors) and iterate based on real user data.
Security belongs in the first design
We review OWASP risks, encryption, authentication, access roles, data retention, and the rules that apply to the product. When the scope calls for it, we also arrange penetration testing and a security review before launch.
Performance is part of the product
We measure the pages and actions users actually need, then improve loading, rendering, caching, images, and network work around those paths. The targets depend on the product and the audience.
Client quotes are published with permission. Review the project pages for scope, delivery, and outcomes.
Corvx project record
The web is still the easiest way to reach people across devices, but the implementation matters. Users notice slow pages, confusing forms, and broken states. We treat those details as part of the system, not decoration.
We work with PWAs, SPAs, server-rendered apps, cloud backends, and existing systems. The right shape depends on the product, the team that will operate it, and what needs to be true after launch.
Questions people usually ask
A website is mostly informational and static (think blogs, marketing sites). A web app is interactive and dynamic, users log in, perform actions, and store data (think Gmail, Notion, Shopify). Web apps require databases, authentication, complex business logic, and often real-time updates. We build both, but we specialize in web apps.
A PWA is a web app that behaves like a native mobile app: it loads offline, can be installed to the home screen, sends push notifications, and loads near-instantly. The benefit? You get mobile app engagement without app store friction or platform fees. Twitter, Starbucks, and Uber all use PWAs, and see 3x higher engagement vs. traditional web.
It depends on your needs. React is the most popular and flexible. Next.js (built on React) adds server-side rendering and static generation for better SEO and performance, ideal for marketing sites and SaaS platforms. Vue is lightweight and beginner-friendly, great for MVPs and fast iterations. We'll recommend the best fit during discovery.
We design for scale from day one: stateless backends, horizontal scaling with load balancers, database indexing and caching (Redis), CDN for static assets, and cloud-native hosting (AWS/Azure/GCP). Whether you have 100 or 10 million users, the architecture adapts. Most importantly, we plan for incremental scaling, so you're not over-provisioning (and overpaying) early on.
Absolutely. We're experts in API integration, Salesforce, HubSpot, SAP, NetSuite, Stripe, PayPal, Twilio, SendGrid, and more. We also build custom APIs if your legacy systems don't have them. API-first architecture means your web app can talk to any system in your tech stack.
Security and compliance are non-negotiable. We follow OWASP best practices, encrypt data in transit (TLS) and at rest (AES-256), implement OAuth 2.0/JWT auth, use role-based access control (RBAC), and conduct penetration testing. For GDPR/CCPA, we implement data subject request workflows. For HIPAA/SOC 2, we use compliant cloud infrastructure (AWS HIPAA, Azure SOC 2) and conduct regular audits.
It varies by scope. A simple MVP with 5-10 features, basic auth, and one user role typically takes 8-12 weeks and $50-80K. A mid-complexity SaaS platform with multi-tenancy, integrations, and analytics takes 4-6 months and $150-300K. Larger platforms with complex workflows, compliance, and scale can take 6-12 months and $500K+. We provide a detailed estimate after discovery.
Yes. Most clients retain us for ongoing feature development, bug fixes, performance optimization, and infrastructure management. We offer flexible retainer models (monthly hours) or dedicated team continuity. Your web app isn't 'done' at launch, it evolves with your business, and we're with you for the long haul.
