IoT Backend Platform

• • Designed and implemented the core backend IoT software architecture; evaluated, selected, and integrated open source components ensuring production-grade reliability and scalability.

• • Integrated Keycloak and WSO2 across open-source and in-house services, consolidating identity management and securing inter-service communication.

• • Designed and deployed mediator/reporter components for device commanding and MQTT payload reception.

• • Designed and evolved a real-time enrichment platform (Java, Spring Boot, Apache Camel, Kafka, EKS) processing

millions of events per day; implemented parallel enrichment and routing pipelines to downstream business flows

with strong resilience patterns (retry, DLQ, fine-grained timeout management).

• • Developed serverless AWS Lambda components for video-clip concatenation and media post-processing (S3 orches

tration, workflow automation), optimizing latency, scalability, and cost. Camera Mediation & Streaming with MAC-based device correlation and structured error handling.

• • Deployed to production via CI/CD (GitHub Actions + ECR) and GitOps (Flux on Kubernetes), with HAProxy providing load balancing, sticky sessions, and TLS termination for scalable, highly available streaming. Edge Infrastructure & Cloud Strategy

• • Designed and deployed a containerized LXC-based edge architecture with full-service orchestration, optimizing

resource management in constrained embedded environments.

processing, and robust connectivity protocols.

• • Enhanced the service ecosystem by integrating Gladys Assistant and Matter protocol services, improving device interoperability and end-user automation capabilities.

• • Provided SI-level technical recommendations for system urbanization and high-level architecture; ensured alignment

between technology choices and business strategy.

• • Led the organizational Move2Cloud program and FinOps practice, migrating workloads to Docker/K8S on AWS and optimizing cloud spend.

Scaled the Sof’CT commission-automation platform to 6 Orange subsidiaries (Tunisia, Jordan, Ivory Coast,

Cameroon, Morocco, Mauritania), covering the full lifecycle from data collection through commission calculation

and reporting.

• Owned the product vision and roadmap: gathered multi-country client requirements, defined release phases, and

delivered quarterly feature sets aligned with local business rules.

• Designed ETL pipelines (Talend Data Integration) consolidating data from heterogeneous information systems;

enforced data-quality checks ensuring calculation accuracy across all markets.

• Developed a configurable back-office validation workflow and a compute engine supporting complex, rule-driven

commission schemes—reducing manual processing and disputes.

• Built REST APIs and a reporting layer (Jasper Reports) producing dashboards and exports consumed by finance

and sales teams across 6 countries.

• Coached new team members and provided production support; established documentation standards and reduced

onboarding time.
