Elixir for real-time, fault-tolerant systems.
When a platform needs to handle thousands of concurrent connections, process events in real time, and never go down. Phoenix, OTP, and the BEAM VM.
elixir-lang.org ↗Elixir powers our most demanding backend systems. Platforms that process real-time data feeds, manage concurrent state across thousands of connections, and require near-zero downtime. We build on Phoenix for API layers, OTP for process supervision and fault tolerance, and Oban for reliable background job processing. Event-driven architectures with CQRS and event sourcing give us full auditability. ETS caching provides sub-millisecond lookups for time-sensitive operations. Every component runs under supervisor trees that self-heal on failure.
The BEAM VM was built for telecom systems requiring extreme uptime. That same foundation makes Elixir ideal for platforms where reliability is non-negotiable. OTP supervision trees mean individual process failures don't cascade. GenServer and DynamicSupervisor make concurrent connection management straightforward without callback hell or complex async patterns. Pattern matching eliminates entire categories of null reference bugs. Commanded gives us event sourcing with full audit trails. When we need a system that handles real-time data, concurrent users, and financial-grade reliability, Elixir is the only answer.
Real-Time Data Platform
GenServer-based feed consumers processing hundreds of events per second across concurrent SSE connections with automatic reconnection and circuit breakers.
Event-Sourced Backend
CQRS architecture with Commanded for domain event processing, complete audit trails, and reliable state transitions across distributed services.
High-Reliability API
Phoenix API with three-tier rate limiting, Oban job queues with retry guarantees, and ETS caching for sub-millisecond response times.
