Recent Success Stories From Software-As-A-Service and Technology-Forward Clients

With nearly two decades of experience partnering with SaaS companies, product teams, and high-growth technology organizations, Keyhole Software is a trusted engineering partner for modernizing platforms, accelerating roadmaps, and building scalable, cloud-native applications that support real-world demand.

Our senior consultants help clients strengthen their product architecture, reduce technical debt, improve performance, and deliver new features faster—and here are a couple of recent examples:

Global Automotive SaaS Analytics Platform

Keyhole Software partnered with a global automotive data and software enterprise to build a customer-facing analytics platform under an aggressive timeline.

Our senior engineering team delivered the full solution — including a modern React dashboard, secure authentication, and a suite of Spring Boot microservices — ahead of schedule and under budget.

The platform was designed using a cloud-ready microservice architecture built with Java, Spring Boot, and Spring Cloud. Keyhole engineers implemented an Edge/API Gateway layer to handle routing, authentication, rate limiting, and tenant-based subscription validation. Redis was used to manage access tokens and improve authentication performance.

On the front end, Keyhole developers built a responsive React + TypeScript application using Material UI, Reach Router for navigation, and Axios for communication with downstream services. The UI included multiple interactive dashboards providing KPI visualizations, geographic heat maps, and multi-country drill-down metrics.

The team delivered a custom JWT-based authentication mechanism supporting both opaque and non-opaque token strategies to meet the client’s external and internal access requirements.

The project successfully delivered a high-performance analytics solution that improved data accessibility, visualization, and customer self-service capabilities across multiple countries and languages. The client gained:

A modern SaaS analytics dashboard that increased user engagement and reduced manual reporting overhead
A secure, scalable microservice foundation that supports future product modules
Subscription-aware authentication ensuring accurate, country-based access control
Faster deployments and more reliable environments through PCF automation
Internationalization support (i18next) enabling multi-language adoption across global regions

Social Media Software as a Service application

React Native Mobile App for a Safe, All-Girls Social Network

Keyhole Software partnered with Miss O and Friends—an international lifestyle brand—to build a cross-platform mobile app that offers a safe, COPPA-compliant social networking experience.

The app, built for a community of girls ages 8–16, required stringent privacy controls, real-time moderation workflows, and a seamless connection to the existing web application and shared backend services.

Using React Native, Keyhole developers created a single JavaScript codebase capable of deploying to both Android and iOS while still leveraging native UI components and platform APIs.

Given the age of the user community, safety was a core requirement. The app incorporates:

Manual content moderation by human reviewers prior to publishing
Filtering for bullying, hate speech, profanity, or personally identifiable information
Full COPPA compliance with parental approval flows
Anonymous user profiles with minimal visible information

The project successfully delivered a secure, mobile-first social networking experience that expanded reach and engagement for Miss O and Friends. Key outcomes included:

A fully cross-platform React Native app launched on both iOS and Android
Significant reduction in development time and cost through shared JavaScript codebase
Seamless integration with existing backend systems and data models

The app strengthened the brand’s mission of providing a positive, bully-free environment for young girls—scaling its community footprint and creating a more modern, accessible way for users to connect.
