Technical Architect

Mudano Ltd., Full-Time

I joined this young Fintech startup's product team as a Software Engineer, and was later promoted to Technical Architect. We applied Data Science to Project Management in a simple to use, yet powerful tool.

2013 - 2015

CTO and Co-founder

DBI Ltd. trading as Undesk.co, Full-Time

Undesk aimed to become a user-centric professional network and platform. We aimed to provide the privacy that LinkedIn lacks as well as niche customisations and third party integrations.

I created a private cloud that would cater to our security and privacy needs. This was implemented on dedicated servers with KVM/QEMU and orchestrated with Puppet. It provided private email, documentation wiki, dev server per developer, etc.

On the application layer, we went with a graph database that fit our needs (Neo4J.) We developed a unix-like access control system that could be applied to any entity or relationship. This allowed us to serve a polymorphic graph API not unlike Facebook's. The frontend was implemented in React in a modular and customisable way with a focus on good user experience.

2012 - 2013

GREE is a Japanese social gaming giant. I worked in its UK studio during its infancy, as a backend and frontend software engineer.

I contributed a forked version of our PHP framework with 20~30% reduced function calls (on average), automatically generated client-server contracts (DTOs) and designed a NoSQL analytics/reporting backend.
