Oronts is a custom software development company and software house in Munich, Germany, specializing in enterprise-grade applications and SaaS platforms. As a software house in Germany with deep engineering roots, we build bespoke software solutions using modern technologies including React, Next.js, Node.js, NestJS, TypeScript, PHP, Laravel, Symfony, Python, Go, Rust, and Java. Our NestJS developers build scalable, modular backend services with dependency injection and a plugin-based architecture that simplifies maintenance and testing. Our architecture expertise spans microservices, event-driven systems, serverless computing, and modular monoliths, each chosen based on your scale, team, and growth trajectory. We develop enterprise resource planning systems, workflow automation platforms, customer portals, internal admin tools, and multi-tenant SaaS products with subscription billing. Our development process follows agile methodology with two-week sprints, continuous integration, automated testing at every level, and zero-downtime deployments. We use PostgreSQL, MySQL, MongoDB, Redis, and Elasticsearch for data storage, deployed on AWS, Azure, or GCP with Docker and Kubernetes orchestration. Every PHP backend engineer on our team builds high-performance APIs with Laravel and Symfony for projects that require proven, battle-tested frameworks. As an API development agency, we design, build, and document REST and GraphQL APIs that power web apps, mobile clients, and third-party integrations. Infrastructure is managed as code with Terraform for reproducible, version-controlled environments. We integrate headless CMS platforms like Payload CMS, Strapi, and Sanity for content-driven applications. Whether you need to replace legacy systems, build a new product from scratch, or integrate disparate tools through custom API development, we deliver production-ready software with full source code ownership and comprehensive documentation.

What Architecture Patterns Do We Use?

The right architecture depends on your scale, team, and growth trajectory.

Enterprise scale

Microservices

Independent services that scale separately. Best for large teams and complex domains.

Real-time systems
Pub
Sub

Event-Driven

Asynchronous communication via events. Ideal for real-time data processing and loose coupling.

Variable traffic
fn

Frequently Asked Questions

Projects typically range from €30K to €300K depending on complexity, number of integrations, and timeline. A straightforward internal tool with a single database and basic user management sits at the lower end. A multi-tenant SaaS platform with payment processing, third-party integrations, and complex role-based access pushes toward the higher end. We provide detailed, itemized estimates after a discovery workshop where we map your requirements, user flows, and technical constraints. This workshop usually takes 2-3 days and costs a fraction of the total project. The estimate breaks down each feature with effort ranges so you can prioritize and phase the build to match your budget. For instance, many clients launch with core functionality first and add advanced features in subsequent sprints. We also flag where off-the-shelf components can save development time, since not everything needs to be built from scratch.
An MVP with core functionality typically takes 8-16 weeks, depending on the number of features and integrations involved. Full enterprise platforms with complex business logic, multiple user roles, and third-party system connections usually run 4-9 months. We work in two-week sprints, so you see working software demonstrated every 14 days, not just slides or wireframes. This cadence lets you course-correct early if requirements change or new priorities emerge. For instance, a startup building a customer portal with authentication, basic CRUD operations, and one payment integration can reach a testable MVP in about 10 weeks. An enterprise workflow platform connecting to SAP, handling document approvals, and supporting multiple teams across regions will take closer to 6-8 months. We also factor in a 2-4 week buffer for testing, bug fixes, and deployment hardening before go-live, because launching with known issues creates more cost than a short delay.
Yes, we adapt to your existing infrastructure and team capabilities rather than forcing a rewrite. Our engineers work across React, Vue, Angular, Node.js, PHP (Laravel, Symfony), Python, Go, Rust, and Java, so we can integrate with most modern stacks. If your backend runs on Laravel and your team knows PHP well, we will build on that foundation instead of suggesting a migration to Node.js for the sake of novelty. We only recommend technology changes when there is a clear, measurable benefit that justifies the disruption. For instance, if your Python monolith struggles with real-time WebSocket connections, we might suggest adding a small Go service for that specific need rather than rewriting everything. In every case, we explain the trade-offs in terms of cost, timeline, and maintenance burden and let you make the final call. Our goal is to strengthen what you already have, not to introduce unnecessary complexity.
After launch, we offer ongoing support packages that cover monitoring, maintenance, security updates, and continued feature development. The first month post-launch typically involves closer attention: we watch error logs, performance metrics, and user feedback channels to catch issues early and deploy fixes quickly. After that initial stabilization, support transitions to a monthly retainer where you get a set number of development hours for new features, bug fixes, and infrastructure updates. We also provide comprehensive documentation covering architecture decisions, deployment procedures, API references, and troubleshooting guides. If your team prefers to maintain the software in-house, we run structured knowledge transfer sessions where our engineers walk your developers through the codebase, testing setup, and deployment pipeline. Many clients use a hybrid approach: their team handles day-to-day maintenance while engaging us for larger feature work or architectural changes.
Yes, we regularly work with startups to validate ideas through focused MVPs. The key is identifying which features actually matter for your first users and cutting everything else. We have seen too many startups spend months building features that nobody uses because they skipped the validation step. Our approach starts with a prioritization session where we sort your feature list into must-have, nice-to-have, and future phases. The MVP includes only the must-haves, which typically means authentication, the core value proposition, and basic analytics to measure engagement. We design the architecture from day one to support future growth, using modular patterns and clean API boundaries so adding features later does not require a rewrite. For instance, a SaaS startup might launch with single-tenant architecture but with database schemas and API contracts that make multi-tenancy a straightforward addition when the time comes.
We use agile sprints with two-week cycles, regular demos, and async-first communication through Slack or Microsoft Teams. Every project has a shared board in Linear or Jira where you can see exactly what is being worked on, what is blocked, and what is coming next. At the start of each sprint, we plan together and agree on priorities. At the end, we demo working software and collect feedback. This keeps expectations aligned and prevents the 'build in silence for three months' anti-pattern. For day-to-day questions, we respond within business hours through your preferred messaging tool. For bigger decisions, we write short proposals with options and trade-offs rather than scheduling another meeting. We share a weekly status summary covering what was completed, what is planned, and any risks or blockers. You always have visibility into progress without needing to chase updates.
