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

What clients say

Google

Amazingly efficient, professional, and excellent work. I recently worked with Kevin and his team on a large project. I plan on using him again and highly recommend his services.

Trustpilot

Two separate projects, consistently positive both times. Professional, responsive, extremely competent, and very easy to work with. They take the time to listen carefully, ask thoughtful questions, and make sure everyone is aligned. Highly capable technically and consistently go above and beyond to keep momentum moving. Even when requirements evolve, they remain calm, collaborative, and solutions-oriented. Would absolutely recommend Kevin, Chris, and the Wavect team.

FAQs

Web app delivery, demystified

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.
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.
Because hours are the wrong metric. If we’re optimizing for hours billed, we’re not optimizing for your outcome. The deal is simpler: every week, we earn the next one. If we don’t, you don’t pay. We’re free to spend zero hours or sixty. What matters is whether you’re blown away.
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.
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.
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.
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.
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 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.
Internal tool with auth, CRUD, and a clean UI: €15-30k. SaaS 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 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.
