Alessandro Teiji(he/him)

I’m a Senior Software Engineer focused on backend and distributed systems, with experience building fintech, payments, credit, and data-intensive products.

My core work includes backend architecture, event-driven systems, integrations, and high-volume transaction processing. I’m backend-first, but I also work across infrastructure, data, frontend, and product when needed. More recently, I’ve been working with Applied AI, using LLM APIs and SDKs to build automation and improve engineering workflows, code review, documentation, observability, and developer productivity and experience.

I’ve built and evolved systems processing more than 2 million transactions per month. My main technologies include Elixir, Phoenix, Kotlin, Scala, Kafka, Spring Boot, PostgreSQL, AWS, GCP, Docker, and Kubernetes.
