Chris Lam
Software Architecture
A veteran software architect at Google for ChromeOS, Chris' fingers write brilliant code, play touching jazz improv on the piano, and clamber up remote mountain faces. If you've used Google products, chances are he's had a hand (or two) in architecting, building, maintaining and refactoring them.

Francois Wouts
Developer Experience
As a prolific indie dev tooling engineer, ex-Senior Staff Engineer at Airtasker and ex-Tech Lead at Google, Francois knows no fear in the face of even the most complex, tech-debt laden codebases. Along with a still Zen mind developed from years of yoga, it's no wonder he's the "Developer Happiness Engineer".

Harrison Scott
Compilers and Full-Stack
Building out the backbone for acclaimed high frequency trading firm Optiver and the university medallist for software engineering, Harrison has placed top of so many academic courses that he probably finds what we do quite trivial. Nonetheless, we work with him as we hope one day he'll write a world class compiler and language for us.

Payment Collection Platform - iOS, Android, Web, Backend



Overview
Overview
Overview
We worked with a client to build a payment collection platform that required integration at the processor level. This meant that rather than using a high-level payment facilitator with high processing fees (e.g. Stripe), we were required to directly connect to a lower level payment processor for more transparency and lower costs.
The client had previously outsourced to an agency but the resulting app had major problems in terms of design and functionality, with crashes a frequent occurence. So we were brought in to entirely rebuild the app and backend.
This required building a backend and database capable of handling a high volume of transactions with high availability. The client-side apps on web, iOS and Android would then interface with the backend to retrieve user and organisation data, as well as to make transactions.
Our rebuild was a resounding success and handled a high volume of transactions during many fundraising campaigns.
Technical Approach
Technical Approach
Technical Approach
Because the existing MVP exhibited technical and design issues, we revamped the visual design and functionality of the app, creating a mockup and then a visual prototype. After this was complete, we began architectural design to determine the most suitable architecture for this relatively complex project.
Once the scope of the project was more understood, we formed a product team composed of a backend specialist, architectural specialist and three full-stack engineers to build the backend, database and the web, iOS and Android apps.
We used Go for the backend, CockroachDB for the database and React, React Native and TypeScript for the web and mobile frontends, with other services such as authentication being handled by Google Firebase.
The result was a highly performant app that performed nearly three times as fast as the previous one, with the level of polish and feel of a top ranking app.
