Our Portfolio - Systems that had to hold

A niche can be right before the system is. These are products we rebuilt or built so the operation could rely on them.

Case studies

Ocean Ops

Rebuild, system design, ongoing technical partnership

A vibe-coded product, rebuilt so the business could run on it

The product already had its niche. The first version was vibe-coded, and the business could not yet run on it. That is the problem Quolo was hired to solve.

We researched the operation first, then rebuilt the system so the hard technical problems were one piece of work. The value is a product the shop can keep using as the work grows.

Another studio could have shipped the rebuild and left. The client kept Quolo for the technical maintenance and for judgement on what the product should do next.

Infinite Stories

Platform build, system design, technical coordination, handoff

A large multimedia product, iterated until it matched the brief

The product was ambitious: a large multimedia system with dense interactions, and more than one party already involved in the work.

Quolo took the technical path — the build, the hosting, and the coordination with those other stakeholders — so the product could keep moving without the technical work splitting across hands.

When the site matched the specifications, Quolo handed it off. We still consult when a technical question comes up.

Weaving Resilience

Web Development, Resource Management System, Security

NGO site and resource management platform

We built the public site and a backend where partner organisations can add and share resources without exposing contributor identities.

Users sit in different countries and comfort levels with software, so the UI had to stay simple. Security around identity was non-negotiable.

We needed a site and a resource tool our partners could trust. Quolo built both and kept the security requirements in view the whole way.

DreamTrip.io

Web development, APIs, payments

Travel planning web app with itinerary generation

DreamTrip.io needed a travel-planning app that turned a short brief into a usable itinerary, with accounts, sharing, and payments — not just a demo chat.

We wired booking and package APIs (including Skyscanner and Viator), Stripe, auth, and a backend that could take real traffic. Model calls for suggestions were capped and shaped so cost stayed predictable.

Quolo took a rough travel-planning idea and turned it into something we could put in front of users — bookings, payments, and the boring backend included.

Investec

Enterprise Web Development, API Integration, Security Implementation

Corporate travel booking suite

Partnering with Investec, a leader in private equity and financial services, our task was to create a robust, secure, and intuitive travel booking platform. This included flights, cars, and package bookings, all integrated with real-time booking APIs like Amadeus.

The project demanded high levels of security and meticulous handling of user data, given Investec's status as a financial institution. We navigated complex requirements for flight bookings from various providers, implemented secure payment processes with 3D Secure, and addressed evolving challenges like COVID travel restrictions and baggage management.

Our solution also included comprehensive backend systems for accounting and booking management, alongside email communication systems.

Working within the framework of a large organisation such as Investec was a challenge, but we were able to deliver a solution that met their needs and exceeded their expectations. We look forward to continuing our partnership with Investec and helping them to achieve their goals.
