Ahmed O.

Senior Software Engineer | Spring-Boot, Microservices, Cloud AWS/Azure

I’m a Software Engineer with a strong foundation in both systems and software engineering, driven by a passion for building scalable and maintainable infrastructure. At Microsoft where I currently work, I’m part of the 1ES (One Engineering System) team, where I help improve developer productivity across the company. I work on services that deliver easily customizable, infrastructure-as-code-defined VM templates, enabling engineers to get up and running with ready-to-code environments in minutes. These solutions are already seeing wide adoption across Microsoft, helping reduce engineering costs while improving consistency and speed. Before that, I was at AWS, where I worked on maintaining hardware load balancers serving a large share of Amazon and AWS traffic, while also contributed to building automated migration services that enabled over 1,000 teams to move to newer Elastic Load Balancing technologies. The system cut down migration time from weeks of manual effort to zero-touch, sub-day workflows—all with zero downtime and built-in safety guardrails. I’ve worked closely with over 100 teams, handled 24/7 on-call support, and delivered high-impact solutions using Java, DynamoDB, and Terraform. These experiences have shaped my ability to operate at scale, deliver reliability under pressure, and drive meaningful improvements for other engineers. I care about writing clean, maintainable code, designing resilient systems, and building tools that let others do their best work—faster.
