Full-stack software engineer

Abrham Aviel Haham

From an unmet need to a working system.

At Mamram / LOTEM, my team built zero-to-one systems when existing products could not meet the requirements. I carried work across frontend, backend, data, cloud infrastructure, and security.

System cross-section / Trace index

One mandate. Five layers of responsibility.

When no existing product fit the need, the team designed and built purpose-specific systems. Across that work, my responsibility crossed the stack from interface to runtime.

An aggregate capability map across multiple systems, not a diagram of any one deployment.
