Context

Subcontracting engagement for the IT services company Tekteo, on production Symfony applications used daily by a large user base — including the business applications of RTM, the urban transport network of Marseille.

Thirteen months of continuous work.

Scope

Fixes and features

API bug fixing and new feature development on applications already in production, with no maintenance window.

Method

Ticket-based work through Redmine, versioning and review on GitLab, integrated into the processes of both the IT services company and its client.

Architecture

Work on custom architectures, through continuous improvement rather than rebuilds.

What this project demonstrates

The ability to fit into an existing subcontracting chain, to sustain a maintenance commitment over time, and to work on high-volume applications I did not originally build — exactly what an IT services company expects from a team reinforcement.
