We act as an experienced safety net for teams running critical systems on the BEAM, helping you design resilient applications, audit performance, and keep dependencies safe and up-to-date.
Praia Labs is an independent engineering consultancy specializing in Elixir, Phoenix, and LiveView. Our founder, Rodolfo Carvalho, chose the name Praia (beach in Portuguese) to represent simplicity, focus, and a sustainable cadence. These values guide our approach to systems engineering and complexity reduction.
We believe in active stewardship and giving back to the BEAM ecosystem: when we encounter bugs or scaling limits in our client projects, we aim to fix them at the core framework level and contribute those improvements back upstream. This keeps our clients' systems aligned with standard releases rather than relying on custom local workarounds.
We bring a foundation built on years of systems infrastructure experience. This includes engineering container platforms at Red Hat, designing distributed storage at AWS, and leading the Web SDKs team at Sentry. We pair this with the experience of building and scaling an educational platform built on LiveView that uses human-centric AI tools for interactive video learning, VideoHub, from the ground up.
We do not sell outsourced headcount or marketing hype. We partner with technology teams to design systems that are simple to understand, performant, and resilient under stress, delivering true engineering peace of mind.
Ensuring your team makes the best use of LiveView by following correct patterns and best practices. We audit code organization, optimize process memory, and resolve state-related bugs to keep your user experiences delightful.
Gaining full visibility into your running system while keeping deployments fast and seamless. We optimize infrastructure hardware sizing to reduce unnecessary costs, set up unified monitoring, and implement zero-downtime releases.
Maintaining a secure and performant system through intentional curation at all levels of the stack. We handle the continuous upkeep of Erlang/OTP, Elixir, the operating system, and key dependencies like Phoenix, LiveView, and Ecto.
Preparing codebases for AI agents to consistently assist your team. We establish the structured context, safe sandboxes, automated testing, static analysis, and clean documentation patterns that autonomous tools require to perform well.
If you run a critical Phoenix application and want the reassurance of having an experienced advisor available, let's start a conversation. We limit concurrent engagements to ensure you and your team get the dedicated attention you deserve, serving as a reliable partner for your production systems.
