Description

I'm Bensalem, a Software Engineer at the German Stock Exchange (Deutsche Börse Frankfurt). I work on the real-time data distribution backbone for one of the world’s leading exchanges. My work powers trading systems through high-performance data streaming and protocol integration (FIX, ETI, MIT, etc.).

What sets me apart? I’m not just a C++ systems developer — I bring the full DevOps and Cloud skillset to design, build, test, and deploy production-ready solutions.

What I Can Do for You:

- Develop ultra-low latency C++ feed handlers & protocol parsers

- Build exchange gateways or enhance trading connectivity

- Optimize multithreaded, high-performance C++ systems

- Integrate FIX/ETI protocols & decode exchange messaging formats

- Containerize and deploy C++ systems (Docker + Kubernetes)

- Migrate workloads to Google Cloud (GCP) or AWS

- Design robust CI/CD pipelines (Jenkins, Terraform, Ansible)

Tech Stack:

- C++ (Boost, STL, Multithreading, Linux)

- FIX, ETI, MIT, exchange protocols

- GCP / AWS / Docker / Kubernetes / Terraform

- Kafka / NATS / AMQP/ RABBIT-MQ/ MQTT / TCP/UDP Multicast / GRPC

- Jenkins, Git, Ansible, CI/CD, Terraform

- Python, Java (for scripting/support)

Clients I've Worked With (via previous companies):

JP Morgan, HSBC, BBVA, Deutsche Börse, FIS, Kepler, Beltone

Whether you're building your market data infrastructure, migrating to the cloud, or optimizing your latency-sensitive C++ codebase, I can help you create something solid, scalable, and fast.
