  Indie Campers

  May 2023 - now

  My main role as a Tech Lead is to lead a team of 4-5 engineers (including myself) as the core team.Our primary focus is on performance optimisation, code standardisation and modelling the data structures around the core system.On a day-to-day I juggle between development, code reviews, mentoring and scoping work and planning new work for the team.I help to design the code patterns, standards and models that support the business to scale.Additionally, due to the lack of a devops team. I work on the CI/CD pipelines to speed up test execution times, monitor database and service performance and intervene when necessary.I implemented an optimisation that improved the latency of an API by 99% in the worst cases. Show less When I arrived at Indiecampers, I was hired as a senior backend engineer. However the team was very small and there was no devops team.So my first work was around CI/CD.The test suite for the monolith application was taking more than 20 minutes to execute and often the task running the tests exceeded the time limit and timed out. I implemented a parallel testing execution which cut the total execution down to about 10 minutes (more than 50% increase).I also performed a few Ruby version upgrades with zero downtime.I worked on and led many projects, with teams between 4 -10 team members. Some of these are: a complete rebuild and simplification for our survey mechanism tool, building a custom feature flagging implementation which facilitated percentage based roll outs, per location or other use cases. I worked on many other projects, bug fixes and incident detection and prevention.I automated many manual tasks that employees were repeating week after week.I led a few different teams of software engineers and was heavily involved with the product team in scoping and discussing possibilities or trade offs.I architected data structures and/or orchestration between services for new features. Deciding on API conventions and payloads.I mentored many of my team mates on best practices, monitoring and building robust and idempotent software.I also performed a full migration of the monitoring tools from New Relic to Datadog for around 4-5 services Show less
