About
Tayam El Jebari
Backend & Distributed Systems Engineer. I work on the identity and access layer of a large microservices estate (a dedicated identity provider and the API-gateway edge), and the event-driven services around it.
I'm on the team rebuilding Albert Heijn's transport platform, where I work on its identity and access layer (a dedicated identity provider and the per-app API gateways) and the event-driven services around it. That means moving a microservices ecosystem off a legacy monolith and a shared static-RBAC gateway onto a dedicated identity provider, policy-based authorization, and event-driven services on Kubernetes. My graduation project, a reusable event-publishing framework built on Kafka and Debezium, is designed for reuse across the estate.
I came to software later than most. I started in Social Work before switching, and that background is where my instinct for systems and the people who use them comes from. What I enjoy most is the layer where a domain problem becomes a clean, durable technical decision, and that's the direction I'm growing in: solution architecture.
How I work
Almost everything I do happens inside a team, and the part I gravitate to is making a problem legible: digging into a system we are about to change, then writing it down as analysis, design notes, or a runbook so the next decision is clearer for everyone, not just me.
A small example: for a cluster-namespace migration I wrote up the steps as a runbook and worked through it together with a colleague, so a fiddly, error-prone change became something a couple of people could follow and double-check rather than knowledge stuck in one head.
It also shows up in bringing people onto new technology. When a group of Oracle developers moved onto the JVM, I designed and delivered part of their onboarding into Kotlin and Spring Boot, so an unfamiliar stack became something they could build with confidently.
