👋 Hey, I’m William Echenim

🚀 I’m a Senior Backend Engineer, Systems Architect who loves building infrastructure that scales — cleanly, efficiently, and reliably.

🧠 Over the years, I’ve engineered real-time bidding engines, telemetry pipelines, and blockchain systems that handle 100K+ events per second and don’t flinch under pressure.

Most of my work sits at the intersection of distributed systems, streaming infrastructure, and real-time decisioning. I enjoy solving challenges around latency, scale, and observability — and I’m most at home when I’m deep in Go, Rust, gRPC, Kafka, Flink, or wrangling performance issues in Kubernetes.

If it’s high-throughput, fault-tolerant, or mission-critical — I’m probably interested.

Let’s just say: I like building things that work even when things go wrong.
