Modern Day Strategy is a Cape Town digital consultancy serving clients around the world. The team asked Complexus to develop OneView, a modern investment management platform for brokers responsible for multi-million-rand portfolios.
We joined an established product direction and carried it through the full technical journey: frontend implementation, secure backend services, and a production-ready cloud deployment.
The challenge
Financial software leaves little room for ambiguity. OneView had to turn dense performance, client, product, and fund data into an interface brokers could understand at a glance, while meeting demanding requirements for security, performance, availability, and usability.
The visual direction was already in place, so our responsibility was to preserve its intent while building the dependable system behind it. We organised the work into focused frontend and backend streams, with both teams collaborating on authentication, data structures, error handling, and the performance of the complete experience.
Making complex portfolio data readable
The dashboard brings high-level performance, assets under management, client records, and portfolio composition into a clear visual hierarchy. Responsive charts are deliberately labelled and easy to filter, helping brokers move from a broad overview to the detail behind each investment without losing context.
Resilience beneath the interface
The calm, focused interface is supported by an architecture designed for dependable day-to-day use. We deployed the application to Google Cloud in containers managed by Kubernetes and introduced two caching layers: React Query on the frontend and Redis on the backend.
That combination reduced unnecessary requests, kept frequently accessed portfolio data responsive, and gave the platform a stronger foundation for availability as usage increased.
The impact
OneView gave brokers a single, responsive workspace for understanding portfolio performance, managing clients, and reviewing investment products. Information that could easily feel fragmented became easier to scan, compare, and act on.
The outcome was more than an attractive dashboard. It was a maintainable investment platform in which the interface, data layer, and cloud infrastructure work together to support confident financial decisions.
