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.
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.
Cancel any week. Last week refunded if we didn't blow you away. No hours tracked.

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.
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.
What else do we offer?
When your project needs something beyond the standard web stack:
Rust: high-performance, safety-critical componentsJava: enterprise-grade backend solutionsC# / .NET: Windows and cross-platform appsPython: data-driven apps and rapid prototyping

HOW WE DEVELOP SOFTWARE
How we develop Software
Five phases. Fixed prices. No lock-in.
Phase 01
Discovery Phase
- Requirements Engineering
- Software Architecture
- Milestone Plan
- Technical Flows and Sequence Diagrams
- Launch Plan and Milestone Plan
Phase 02
First Iteration
- Building your real MAP (Minimal Awesome Product)
- Cost-effective approach. Strip requirements to 15–20k max
- Test directly on the market as cheaply as possible with real customers
- Discovery Phase cost is deducted as a rebate
Phase 03
Subsequent Iterations
- Building and extending product based on real customer/user demand
- Ideally partially funded by real sales
- Data-driven development decisions (watch user behavior over user demands)
- Continuous improvement cycle
Phase 04
Maintenance
- Security patches (nobody likes data breaches or losing money)
- Fixing bugs (can be a major reason of customer churn)
- Technical support (most companies have an abysmal customer support)
- Performance, cost & CI/CD optimization
Phase 05

What clients say
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.
Clutch
Delivered on time and overdelivered most of the time.
AI summary · Clutch
Wavect GmbH helped the client gain a better understanding of their IT infrastructure and business, resulting in increased efficiency and problem-solving speed by around 50%. Moreover, the team delivered on time and communicated via meetings. They were timely, accurate, and straightforward.

Start with the business task
For external account journeys, see customer portals
. For transfers between existing systems, use API integration
. Public pages and editorial workflows belong with website development
. A product with several interacting workflows stays here.
React and Next.js: new features, existing apps and upgrades
Bring the current versions, dependency constraints, backend contracts and the user journey you need to change. We assess the existing code before recommending a migration. Choose rendering and data loading around public content, authenticated state and deployment constraints. Include forms, authorization boundaries, keyboard use and failure states in acceptance tests. Measure performance in an agreed environment before making an improvement claim. Bond Analytics
publicly lists React; it is not evidence of a Next.js-specific result. Agree source, test and deployment handover for the chosen scope.
Node.js and NestJS: the product backend
Backend scope starts with business rules, data models, permissions and API consumers. A background job needs a duplicate rule, bounded retries, a failure owner and an explicit consistency decision. NestJS is an option, not a reason to replace a working stack. Bond Analytics
publicly lists NestJS and TypeScript. Extending an inherited backend starts with takeover assessment
; exchanging records between existing tools belongs with integration
. Agree dependency updates, tests, deployment and operating ownership.
Internal tools: approvals and operational views
For employee tools, define the task, roles, approval history and system that owns each record. Configure an existing tool when its rules, access and costs fit. Consider custom work when exception handling and domain rules justify maintaining it. User count, licences, integrations and the maintenance owner belong in the decision. The Retool three-year cost comparison
provides an explicit model; it does not quote your project. External company accounts instead belong with customer portals.
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 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.
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.
We assess your requirements, current code, dependencies and team before choosing a stack. React, Next.js, Node.js and NestJS are part of our published web stack. For another existing framework, confirm fit through assessment rather than assuming a forced migration or unlimited support.
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.
We assess existing and legacy codebases before agreeing maintenance, extensions or modernization. Review repository and infrastructure access, versions, business-critical flows and release risks first. Specific platform support is confirmed in that assessment. For a provider transition, see Software Takeover
.
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.
