About me
Abdelrahman Mahmoud¶
Enterprise Software & Integration Engineer · Red Hat Certified OpenShift Administrator
I'm an Enterprise Software & Integration Engineer at Valleysoft. I design and build backend services with Java and Spring Boot, connect enterprise systems with IBM Cloud Pak for Integration, App Connect Enterprise and API Connect, and run workloads on Red Hat OpenShift, where I'm a Red Hat Certified Administrator.
I started on the infrastructure side as a System Engineer: Linux servers, networking, reverse proxies, certificates and production support. That background shapes how I write software today. The services I build are designed from day one to be deployed, secured, monitored and operated, and when something breaks I can follow the problem across the application, middleware and infrastructure layers.
What I bring¶
-
Backend engineering
Java and Spring Boot services, RESTful APIs, PostgreSQL, and Angular front ends for enterprise applications.
-
Integration
IBM CP4I, App Connect Enterprise and API Connect: integration flows, API contracts, transformations and API security policies.
-
OpenShift & containers
Red Hat certified OpenShift administration, Kubernetes and Docker for production workloads.
-
Identity & access
Keycloak, LDAP, SSO, OAuth 2.0, OpenID Connect and JWT across many applications.
-
Linux & infrastructure
Linux administration, networking, Nginx, reverse proxies, SSL/TLS and incident troubleshooting.
-
Delivery
GitLab CI/CD pipelines and deployment workflows for applications and integration services.
How I work¶
Understand¶
Clarify the business goal, the systems involved and the constraints first.
Design¶
Define API contracts, data flows and the security model before writing code.
Build & ship¶
Deliver in small, demoable increments through automated pipelines.
Operate¶
Monitor, document and support the system after it goes live.
Principles¶
- Simple beats clever. Systems the next engineer can read, change and operate with confidence.
- Security is designed in. Authentication, authorization and auditing from the first sprint.
- Contracts first. Integrations stay stable when APIs and messages are agreed up front.
- Clear communication. Regular updates, honest estimates and no surprises.
