Custom Development

Web & Native App - Development

We build custom web applications, APIs and native mobile apps using Symfony, PHP and modern JavaScript — from internal business tools to customer-facing platforms that scale.

Why custom development?

When off-the-shelf isn't enough

Standard platforms work well for standard problems. When your business logic is specific — complex workflows, unusual data models, deep integrations or strict performance requirements — custom development is the right answer.

Our team builds on Symfony and PHP for robust backends, React and Vue.js for rich frontends, and React Native for cross-platform mobile apps. Everything we deliver is clean, tested and designed to be maintained by your team long after we're done.

What we offer?

Custom Web Applications

From internal dashboards and portals to customer-facing platforms — we design and build web applications that fit exactly how your business works, not the other way around.

  • Symfony & PHP backends
  • React / Vue.js single-page applications
  • Multi-tenant & SaaS architectures
  • Role-based access control & audit logging

Native Mobile Apps

We build iOS and Android apps using React Native — sharing most of the codebase across platforms while delivering a native feel on both. Connected to your existing backend via clean REST or GraphQL APIs.

  • React Native (iOS & Android)
  • Push notifications & offline support
  • App Store & Google Play deployment
  • Ongoing maintenance & OS updates

API & Backend Development

We design and build APIs that are clean, versioned and well-documented — whether you need a REST backend for a mobile app, a GraphQL layer for a headless frontend or a microservice breaking a monolith apart.

  • RESTful & GraphQL API design
  • OAuth2 / JWT authentication
  • OpenAPI / Swagger documentation
  • Async queues & background processing

DevOps & Cloud

We set up CI/CD pipelines, containerised deployments and cloud infrastructure so your application ships reliably and scales without drama. We work with AWS, Hetzner and other providers.

  • Docker & Kubernetes deployment
  • CI/CD with GitHub Actions / GitLab CI
  • AWS, Hetzner & custom VPS setups
  • Monitoring, alerting & SLA support
Why MVSoft?

Senior Developers Only

No juniors learning on your project. Every developer we put on a project has the experience to make good architectural decisions independently.

Clean, Testable Code

We write code that is readable, documented and covered by tests — so your in-house team can maintain it confidently after handover.

Full-Stack Capability

One team handles backend, frontend, mobile and infrastructure — no coordination overhead between multiple agencies or freelancers.

Fast Time-to-Market

Our library of Symfony service patterns and React components means we start faster without cutting corners on quality.

Transparent Communication

Short sprints, regular demos and clear progress updates. You always know exactly where your project stands.

Long-Term Partnership

Most clients stay with us for years. We invest in understanding your business so every engagement builds on the last.

FAQ

For backends: PHP 8, Symfony 6/7, Doctrine ORM and PostgreSQL or MySQL. For frontends: React or Vue.js depending on the project. For mobile: React Native. For infrastructure: Docker, CI/CD with GitHub Actions and cloud hosting on AWS or Hetzner. We choose the best tool for each context — not just what we know best.

Yes. We use React Native to target both iOS and Android from a shared codebase, which significantly reduces cost and maintenance overhead compared to native-only development. Where we need a platform-specific native module, we build it — React Native is not a limitation.

Yes. We regularly take over applications from other agencies or in-house teams. We start with a codebase review to understand the current state, identify risks and agree on a scope for stabilisation or evolution. We don't require a full rewrite unless the code genuinely can't be salvaged.

A focused internal tool or portal typically takes 8–14 weeks. A full B2B platform or customer-facing application with complex workflows usually takes 16–28 weeks. We always start with a discovery phase to define scope and milestones before writing a line of code.

We offer post-launch maintenance retainers that cover bug fixes, security updates and small feature additions. Most of our clients stay with us long after the initial launch — we become the technical team behind their product, not just the agency that built it.
