Custom Software Development

Web Application Development

Full-stack web applications and progressive web apps built on modern frameworks. React, Vue, or Angular frontends with scalable, API-first backend architectures. Engineered for performance, security, and long-term maintainability.

For CTOs replacing legacy web apps with modern, scalable platforms

For product teams building customer-facing SaaS web applications

For founders launching web-first MVPs that need to scale

The Problem

Why Web Applications Underperform

Slow load times

Pages that take 4+ seconds to load, bleeding users and tanking conversion rates. Every 100ms of latency costs revenue.

Accessibility gaps

Web apps that exclude users with disabilities, creating legal exposure and locking out a significant portion of your audience.

SEO invisibility

Client-rendered SPAs that search engines can't index, making your product invisible to organic traffic.

Security vulnerabilities

XSS, CSRF, and injection attacks waiting to happen because security was an afterthought, not an architecture decision.

Scaling bottlenecks

Monolithic frontends and tightly coupled backends that buckle under traffic spikes and can't scale horizontally.

Our Approach

Performance-First Web Engineering

We build web applications that score above 90 on Lighthouse from day one, not as an afterthought. Every architecture decision is measured against Core Web Vitals, accessibility standards, and SEO requirements before a single component is built.

Server-side rendering & static generation

SSR for dynamic pages, SSG for marketing and content — the right rendering strategy for each route, not a one-size-fits-all approach.

API-first architecture

Decoupled frontend and backend with typed API contracts, enabling independent deployment cycles and team autonomy.

Progressive web app capabilities

Offline support, push notifications, and installability — native app experiences delivered through the browser.

Component-driven development

Reusable, tested UI components in a shared design system, ensuring visual consistency and faster feature delivery.

CI/CD from sprint one

Automated testing, linting, and deployment pipelines configured before the first feature is built — not bolted on later.

How We Work

Engagement Models for Web Development

Fixed-scope project

Defined requirements, fixed timeline, milestone-based payments.

Best for: Well-scoped web apps, marketing sites, PWA builds.

Dedicated engineering pod

Cross-functional team (4–8 engineers) embedded in your workflows.

Best for: Multi-year SaaS platforms, ongoing feature development.

T&M sprint teams

Flexible capacity, 2-week sprints, scale up or down as needed.

Best for: Evolving requirements, R&D phases.

CTO-as-a-Service advisory

Strategic architecture guidance, framework selection, performance roadmap.

Best for: Organizations without a technical co-founder or CTO.

Results

Web Application Outcomes We Can Point To

Fintech

Challenge: Fintech startup with a React SPA scoring 34 on Lighthouse, no server-side rendering, and zero organic traffic despite strong product-market fit.

Approach: Migrated to Next.js with ISR, implemented a GraphQL BFF layer, and achieved WCAG 2.1 AA compliance across all user flows.

FAQ

Frequently Asked Questions

Should we use React, Vue, or Angular?
It depends on your team and ecosystem. React has the largest ecosystem, Vue is simpler for smaller teams, Angular is strong for enterprise with TypeScript-first architecture. We'll recommend based on your specific context.
What's the difference between SSR, SSG, and CSR?
SSR renders pages on the server per request (great for dynamic content), SSG generates pages at build time (fastest, ideal for marketing), CSR renders in the browser (good for dashboards). Most apps use a mix.
How do you ensure WCAG compliance?
We use axe-core in CI, manual screen reader testing, keyboard navigation audits, and color contrast verification. Accessibility is tested in every sprint, not just before launch.
Can you migrate our legacy web app to a modern framework?
Yes. We use a strangler fig pattern — incrementally replacing legacy components while keeping the existing app running. No big-bang rewrites.
How do you handle SEO for single-page applications?
SSR or SSG eliminates the core problem. We also implement structured data, canonical URLs, meta tags, and sitemap generation as part of every web app.
What does your testing strategy look like?
Unit tests with Vitest/Jest, integration tests with Testing Library, E2E with Playwright, visual regression with Chromatic, and accessibility audits with axe-core — all in CI.
