Over Firas

Backend Engineer with 5+ years delivering Scala, Java, and Python services on AWS. I design and harden microservices and event-driven systems, optimize PostgreSQL and Neo4j, and automate delivery with Docker/Kubernetes, Terraform, and modern CI/CD. Recent wins include cutting p95 response times by ~25%, stabilizing flaky services, and reducing deployment friction with trunk-based pipelines and observability (metrics/logs/traces). I’m a hands-on builder who communicates clearly and leaves teams with clean docs and measurable outcomes.
