Description

Over the last 8+ years, I’ve built actor-based architectures in Rust (Kameo), C# (Orleans), and Erlang/OTP that power:

- High-throughput financial pipelines (25x performance improvements)

- Real-time messaging & collaboration tools

- Audio/video processing with WebSockets & WebRTC

- Orchestration engines using Temporal.io and event sourcing

🔁 My specialty is turning vague specs into scalable prototypes:

You give me an idea, I model it (DDD, actors, events)

I build resilient systems that are testable under load

📡 Tech I love:

Rust • C#/.NET • Erlang/OTP • Orleans • Temporal.io • Kafka • WebSockets • Redis • PostgreSQL • Actix • CQRS

Rust developer
March 2025 - Today (1 year and 3 months)
Bucharest, Romania
Designed and implemented a backend system in Rust for an early-stage audio editing platform, focusing on track management and audio playback control.

Built an actor-based architecture using Kameo, modeling users, tracks, and audio players as message-driven entities Developed RESTful and WebSocket endpoints using Actix-Web and Tokio, enabling real-time control over audio playback (play, pause, seek) and user-specific track CRUD operations.

Tech: Rust, Actix, Tokio, Kameo (actor model), async/await, unit testing (rstest) WebSocket, REST
