Complete SaaS products from architecture and UX through APIs, data, payments, and production operations.
You have raised a seed or Series A and need senior execution before another full-time hire makes sense. We integrate with your workflow, using the same Slack channels, standups, and sprint board to keep delivery visible and aligned.
Your MVP got you to product-market fit, but the architecture will not support the next stage. We assess the codebase and build a systematic improvement plan: no big-bang rewrite, just targeted changes that improve reliability and delivery speed while the product keeps running.
You have an internal project that needs focused delivery while your in-house engineers stay on the core product. Cavanex handles the architecture and implementation across frontend, backend, APIs, data, auth, payments, and CI/CD, with a documented handoff when the project is complete.
We start by understanding the business, not just the codebase. Discovery covers existing code, stakeholder requirements, user flows, and technical architecture. The output is a technical specification, data model, API contracts, and a phased project plan that you approve before production implementation begins.
This is where the foundation goes in: data models, APIs, authentication, authorization, and the primary user flows. Every two weeks you get a working application in staging that uses real schemas and connects to the systems it must support.
We complete the remaining features, third-party integrations, analytics, monitoring, and CI/CD pipeline. Unit, integration, and end-to-end tests are written alongside the product rather than added at the end. The result is a complete application in a staging environment that mirrors production.
We deploy to production, configure monitoring and alerting, run load tests, and watch the launch closely. Every system is documented through architecture diagrams, API documentation, deployment procedures, and runbooks. The engagement can end with a structured handoff or continue under an ongoing support retainer.
React and Next.js are the default for web applications because the ecosystem and tooling are mature. TypeScript is used on every project.
The runtime follows the problem: Node.js for real-time applications, .NET for complex business systems, Python for data-heavy workloads, and Go for high-performance services.
Database choice follows the data model and query patterns. PostgreSQL is the default for relational data, MongoDB for document-heavy workloads, Redis for caching and real-time features, and DynamoDB for serverless systems at scale.
Every application runs on production-grade infrastructure from day one: AWS for most projects, Docker for containerization, Kubernetes when orchestration is justified, and Terraform for infrastructure as code.

Most platform builds run 8-16 weeks for an MVP, depending on complexity. A simple SaaS application with authentication, a core workflow, and basic integrations typically lands around 8-10 weeks. More complex platforms with multiple roles, payments, integrations, and reporting push toward 12-16 weeks. We break engagements into 2-week sprints with working demos, and larger projects begin with a phased roadmap so an initial version can launch while the remaining work continues.
Yes. Many engagements involve taking over or extending an existing codebase. We audit the architecture, technical debt, test coverage, and deployment pipeline, then recommend what should be retained, refactored, or replaced. The goal is a pragmatic plan, not an automatic rewrite.
We offer ongoing support for maintenance, feature development, infrastructure management, and production issues. A clean handoff is also available, including architecture diagrams, API documentation, deployment guides, runbooks, and structured knowledge transfer. You own 100% of the code and IP from day one.
Delivery is managed through weekly or asynchronous updates, a shared Slack channel, and a visible task board in Linear or the tool your company already uses. Every sprint starts with planning and ends with a working demo, so you can see what is complete, what is next, and where the project stands.
Cavanex works on either a fixed-price project basis or a monthly retainer. Fixed-price works best for clearly defined projects; retainers fit ongoing work where priorities can shift. Typical engagements range from $30K-$150K+ depending on scope, complexity, and duration. You receive a detailed proposal after discovery so the milestones, deliverables, and costs are explicit.
Many clients need more than one isolated service. Cavanex connects platform engineering, cloud infrastructure, and SOC 2 implementation through one coordinated delivery model.
