Key Deliverables

Steven joined Newcross at a critical time of change. The initial intention was for him to continue the work of previous engineers in a small team maintaining a highly impactful healthcare platform that helped to improve people’s lives and was very much in demand. However it quickly became evident that the tech debt accumulated over years made the platform hard to maintain, let alone grow the business.

Steven went from being a Senior Engineer in a team of 2, to interviewing and leading a team of 10 engineers and testers. All the while helping to mentor and upskill new hires, removing blockers, automate deployments, track down issues in production, improve the platform to make sure it was performant and reliable, and being responsible for cross-functional collaboration.

Feedback

Here is feedback on Linkedin.

Working with Steven was great. He joined Newcross at a critical time and quickly became an essential part of the backend team. He then took charge of our platform backend and made significant contributions towards performance improvements, build automation, bug fixes and setting up a strong engineering practice within the team. He also helped in laying the foundations of migrating Monolith to Microservices. Very happy to recommend him.
