--- title: "Web Apps" canonical: https://wavect.io/services/web-apps/ language: en description: "We design and build web applications that stay fast, reliable, and maintainable as usage grows. NestJS, NextJS, React, Angular, VueJS, and more." image: "https://wavect.io/img/general/bak/open_graph_preview.jpg" --- Web Development # Web App Development We take web applications from the first architecture decision to a monitored production release. One senior team owns the frontend, backend, and the seams between them. - 75+ products shipped - 10+ years experience - No-Bullshit Guarantee // 01 ## What technologies do we use? We pick the stack that fits your project, timeline, and future hiring needs, not our personal preferences. NestJS Scalable server-side applications with structured architecture and TypeScript-first design. NextJS High-performance React with SSR and static generation. Our go-to for production web apps. React Dynamic, component-based UIs with a massive ecosystem. Works at any scale. Angular Enterprise-grade SPAs with strong typing and structure for complex business applications. VueJS Lightweight and progressive. Great for lean teams who need to move fast without the overhead. TypeScript Strong typing across the stack. Catches bugs before production, makes onboarding faster. // 02 ## How do we run development? No waterfall surprises. You see working software at every milestone. 1 Requirements Analysis We clarify your goals, constraints, and user needs before writing a line of code. 2 Architecture Design A scalable structure agreed upfront. No expensive rewrites 6 months later. 3 Agile Development Short iterations with working software at every milestone, not just at the end. 4 CI/CD Pipeline Automated builds, tests, and deployments so updates ship reliably and fast. 5 QA & Testing Unit, integration, and E2E tests as first-class citizens, not an afterthought. // 03 ## What else do we offer? When your project needs something beyond the standard web stack: Rust: high-performance, safety-critical components Java: enterprise-grade backend solutions C# /.NET: Windows and cross-platform apps Python: data-driven apps and rapid prototyping HOW WE DEVELOP SOFTWARE ## How we develop Software Five phases.

End any week, with one message. No notice period, no exit interview, no fine print. We invoice weekly, so the most you’re ever committed to is the current week. ### What if I'm not blown away by the work? It’s in your contract: tell us, and we refund that week. No questions, no invoices to dispute, no calls to escalate. The only rule: refunds apply to the most recent week. ### Why don't you track hours? Because hours are the wrong metric. If we optimize for hours billed, we do not optimize for your outcome. The deal is simpler: every week has a defined result, and we earn the next week by delivering it. You pay for progress against that result, not for a timesheet. ### What does 'expectations detached from reality' mean? We work with operators, not lottery winners. If a request would require breaking physics, the law, or a third party’s systems, we say so, and if we can’t align, we walk. The guarantee is mutual: you can fire us any week; we can also fire ourselves. ### Which framework will you use, and do I get to choose? Default stack is Next.js + NestJS + Postgres, because it scales from prototype to enterprise without rewrites. We’re equally comfortable with React, Vue, Angular, or SvelteKit on the front and Node, Django, Rails, or Go on the back. If you have an existing stack, we use yours. We don’t force-migrate. ### How do you handle SEO and performance on SPAs? SSR or SSG by default (Next.js, Nuxt, Astro), never a JS-only blank shell on first paint. We hit Core Web Vitals targets (LCP under 2.5s, CLS under 0.1) before launch. Image optimization, route-level code splitting, edge caching, and proper Schema markup are the bare minimum, not the deluxe package. ### Can you take over an existing codebase or only do greenfield? Takeovers are a real specialty. Our first 1–2 weeks on a brownfield project: audit, document architecture, identify quick wins and structural risks, then deliver a written plan before changing significant code. We’ve inherited.NET Framework, PHP/Symfony, Python/Flask, and similar projects (no Rails) and modernized them without big-bang rewrites. For a full provider transition from another agency, freelancer, or internal team, see [Software Takeover](/services/software-takeover/). ### Where does the app run, and what happens on deploy day? We deploy to whatever fits the workload and your operations team: Vercel, Netlify, or Cloudflare for edge-heavy frontends; AWS, GCP, Azure, or Hetzner for backends; self-hosted Docker/Kubernetes when there are data-residency or compliance reasons to keep it in your own infrastructure. [CI/CD](/glossary/ci-cd/) is set up from day one: preview deploys per branch, automated tests gating production, one-command rollback. You should never be afraid to ship on a Friday. ### What does a custom web app cost end-to-end? Internal tool with auth, CRUD, and a clean UI: €15-30k. SaaS [MVP](/glossary/mvp/) with billing, multi-tenant data, and a marketing site: €30-80k. Production platform with admin tools, SSO, audit logs, and SLA-grade ops: €100k+. Hosting, third-party APIs, and ongoing maintenance are quoted separately so the build budget doesn’t quietly absorb runtime costs. ### When should we extend a SaaS or no-code platform instead of building custom? When your differentiation isn’t in the workflow itself. Webflow, Retool, Airtable, Bubble, and Supabase will outpace a custom build for 80% of internal tools and 60% of MVPs. We push back when a founder wants custom code for a problem a €99/mo SaaS already solves. We build custom when the differentiator is real: domain-specific logic, data ownership, integrations with proprietary systems, or compliance that off-the-shelf can’t deliver. // More in ## More in Software Development ### [Custom Software Development](/services/software-development/) End-to-end delivery across web, mobile, AI, and blockchain.
