Hire Elixir & Phoenix Developers

Elixir is the right choice when you need massive concurrency, real-time bidirectional communication, or extreme fault tolerance as product requirements. The Erlang VM handles millions of lightweight processes with preemptive scheduling, making it exceptional for chat systems, collaborative tools, IoT data pipelines, and financial systems where uptime is non-negotiable. Node.js and Go are better choices when the ecosystem and hiring market are primary concerns and concurrency requirements are modest.

Standard placement is within one week of contract signing. Elixir is a specialised language with a smaller hiring pool than mainstream ecosystems. We maintain bench capacity but lead times are slightly longer than for React or Node.js profiles. For developers with specific OTP and distributed systems experience, two weeks is realistic.

Phoenix LiveView is a server-rendered interactive UI system that updates page content over a persistent WebSocket connection. It eliminates the need for a separate JavaScript frontend framework for many interactive UI patterns - forms with real-time validation, live search, dashboards with auto-refreshing data, and collaborative features. We recommend LiveView when the team prefers server-side rendering simplicity and the UI requirements do not demand complex client-side state.

Yes. Our developers review the existing codebase structure, OTP supervision tree, Ecto schemas, and test coverage before making changes. Elixir codebases with a well-designed OTP architecture are straightforward to extend; those with misused processes or missing supervision trees require upfront refactoring that we identify and plan in the first week.

Phoenix Channels are our foundation for real-time features - they provide a multiplexed WebSocket transport with topic-based pub/sub, presence tracking, and clean client library support. For server-to-client push (notifications, live dashboard updates), Phoenix LiveView is often the simpler choice. We design real-time architectures that scale horizontally using Phoenix.PubSub with a distributed backend.

Yes. Distributed Erlang - clustering nodes, global process registration, and consistent hashing for process placement - is a core competency. Our developers have built distributed Elixir systems for high-availability use cases and understand the trade-offs involved in distributed state, network partitions, and CAP theorem constraints in practical systems.

ExUnit is the standard Elixir test framework and we use it extensively - unit tests for pure functions, integration tests for Ecto queries against a real test database, controller tests for API endpoints, and LiveView tests for interactive UI components. We write tests with ExMachina factories for clean test data and configure CI to run the full suite on every pull request.

Yes. Absinthe is the mature Elixir GraphQL library and our developers use it to build schema-first GraphQL APIs with type definitions, resolvers, middleware, subscriptions over WebSocket, and DataLoader for batching related data queries efficiently. We have experience connecting Absinthe APIs to both React and mobile frontends.

PostgreSQL with Ecto is our standard data layer. Ecto provides composable query building, migration management, database constraints, and a clean separation between the query layer and the changeset validation layer. For specific use cases - time-series data, search, or key-value storage - we integrate TimescaleDB, Elasticsearch, or Redis alongside PostgreSQL.

Yes. We configure release builds with Mix releases, containerise with Docker, and deploy to Fly.io, Railway, or bare cloud VMs. We configure clustering for multi-node deployments when your concurrency requirements demand it, implement health checks, and set up distributed tracing with OpenTelemetry so production behaviour is observable.

Yes, with the caveat that we always assess whether migration is genuinely warranted. If your Node.js backend is handling load well, migration cost may exceed the benefit. If you have real concurrency problems - WebSocket scale, process isolation failures, or reliability issues - Elixir migration produces dramatic improvements. We produce a migration plan with phased delivery so the new system can be validated in production before the old one is retired.

We offer monthly retainer and time-and-materials models. Retainer engagements include a fixed monthly allocation of developer hours with guaranteed availability. T&M engagements are billed weekly against tracked hours with full transparency. Both include a dedicated account manager. Minimum engagement is one month, with most Elixir projects running three to nine months.
