Icaro Kiiler Melo

I’m a software engineer with over 4 years of experience in fullstack engineering and cloud-based solutions architecture, specializing in Node.js and AWS environments. I focus on building backend systems that are measurable, reliable, and built to scale.

In my recent work, I scaled processing to 130K daily events and improved API performance with 40% faster response times. I also increased system success to 99.9% uptime and reduced error rates by 65% by modernizing legacy services into event-driven microservices and strengthening observability with Prometheus and Grafana.

I’m passionate about turning complex integrations into dependable workflows. I integrated with Brazil’s national NFSe provider using Node.js, Express, and Kafka—processing 10K+ invoices monthly—and built an analytics product (Asas BI) that increased revenue by 7%.

I bring a hands-on engineering mindset: architecting microservices with NestJS, Kafka, and Kubernetes; implementing end-to-end monitoring; and continuously improving streaming provider integrations. I’m now seeking a BackEnd Engineer role where I can apply my backend engineering and cloud architecture skills to deliver efficient, innovative audio content solutions.
