Tech partnerships we’re proud of
Everything You Need to Launch & Scale
We bring together product thinking, backend architecture, and cloud best practices to build SaaS and PaaS platforms that are secure, scalable, and user-friendly—so you can focus on growth, not infrastructure.
Multi-Tenant Architecture

We design for scale from the start—building multi-tenant systems with proper data isolation, shared services, and role-based access across user groups.

Authentication & Access Control

From login flows to enterprise SSO, we implement flexible and secure auth using JWT, OAuth2, Auth0, or AWS Cognito—customized to your platform needs.

Subscription Billing Integration

We set up Stripe, Chargebee, or Paddle for monthly, annual, or usage-based billing—fully synced with your backend and user tiers.

Admin Panels & Dashboards

We create intuitive control panels for users and teams—covering settings, usage, billing, permissions, and platform management.

Modular API Design

We build clean, versioned APIs that make your platform extensible—supporting internal logic, third-party integrations, or even public API usage.

Advanced Add-Ons
These features help your SaaS or PaaS product stand out—giving you enterprise readiness, real-time functionality, and full observability.
Usage Tracking & Metered Billing

We implement usage analytics for tracking feature access, API calls, or seats—feeding into dashboards and metered billing systems.

Feature Flag Systems

Roll out features safely with built-in toggles, staged releases, and customer-specific enablement using tools like LaunchDarkly or custom toggles.

Real-Time Collaboration

We add WebSocket or event-based systems for live syncing, updates, and multiplayer workflows inside your SaaS product.

Audit Logs & Activity History

Track user and system activity for compliance, transparency, or troubleshooting—stored securely and easy to query.

What We Stand For

The reason behind every decision, product, and partnership.
1

Discovery and Scoping

We clarify your product goals, target users, monetization model, and must-have features—defining what the first version should do and how it will scale.

2

System Architecture Design

We design the backend, tenanting strategy, deployment plan, and database structure—whether you’re building on AWS, GCP, or a hybrid cloud stack.

3

Feature Development in Sprints

We work in agile sprints—building core modules like auth, billing, dashboards, and admin tools while keeping your roadmap in focus.

4

Testing Staging and Security Hardening

We test functionality, permissions, and edge cases—setting up staging environments and locking down data access and API security.

5

Launch Monitor and Improve

We help you go live with analytics and error monitoring in place—and stick around to support growth, updates, and enterprise readiness.

Hear It from Our Clients

We could tell you how great our team is—but we’d rather let our clients do that for us.

RigRex is top-tier!!! Point blank. My experience spans decades in the software industry (Consultancy to Defense to Consumer to Agency to Enterprise) and I can honesely state that RigRex is one of those rare stars in doing what he does.

Malcolm Johnston

We have been working with RigRex for almost 2 years now. During that time RigRex has worked on different front-end projects for us, using both Nuxt 2 and Nuxt 3. We have found Hafiz to be a knowledgeable front-end developer who keeps to timelines and is enthusiastic to improve his skills. Most importantly we have enjoyed working with RigRex, found him to be a good and prompt communicator who is willing to go the extra mile when needed.

Rigrex was a key contributor—skilled, collaborative, and excellent in Spring Boot delivery.

We’re as good as our last project

Building a SaaS or PaaS Product?

We specialize in platform thinking. These FAQs address pricing models, feature sets, scalability, and what to expect when launching a service-based product.
What’s the difference between SaaS and PaaS?

SaaS (Software as a Service) is a complete product delivered to users. PaaS (Platform as a Service) lets others build on your infrastructure or services. We build both, depending on your business model.

Can you build a billing system into our platform?

Yes—we integrate with Stripe, Chargebee, Paddle, or your preferred provider to handle subscriptions, usage-based billing, and invoicing.

Do you support enterprise features like SSO and audit logs?

Absolutely. We build enterprise-ready features including SSO (SAML/OIDC), audit trails, permissions, role hierarchies, and API rate limiting.

What cloud platforms do you work with?

We support AWS, GCP, Azure, and hybrid setups. We’ll recommend the right approach for your scale, budget, and DevOps readiness.

Can you help us go from MVP to full product?

Yes. We often help startups validate and launch their first version—then evolve the platform as users grow and needs expand.

Do you offer long-term support or handoff?

Both. We can either hand off with full documentation and training or stay onboard to help maintain and grow the platform over time.
