Description

Technical Lead - Back-end Developer - BPMN Expert

Over 20 years of practical experience with Java/J2EE and distributed architectures.

Very good knowledge of software development, and strong experience in technical architecture, I have accumulated nearly 10 years of component integration as an Integrator, Technical Lead, and DevOps Lead. This strong experience in studies, design, implementation, and qualification allows me to approach future projects with a qualitative approach.

Automation of CI/CD pipelines, implementation of integration and load test automation, challenging development teams through code and release validation, support for operations and testers, risk management, alert raising, leading project committees with the client and various impacted teams are among the tasks I regularly handle.

I have particularly good mastery of microservices architectures, BPM, and a preference and expertise in back-end development on about ten projects. I enjoy validating and presenting my architectural recommendations and studies to my hierarchy and colleagues through POCs.

Trainer at SupInfo, a leading school in computer engineering education, recognized for its practical and innovative approach that prepares its students for high-level careers in the technology sector.

In this context, I have the opportunity to share my knowledge in advanced algorithms, graph theory, Python and C++ programming, and optimization. My missions include designing and leading theoretical and practical courses, applying innovative pedagogical methods to help future engineers master key concepts and implement them in real projects.

Tasks:

• Teaching graphs, search algorithms, and properties (Eulerian, Hamiltonian).
• Solving assignment and scheduling problems through graph coloring.
• Applying shortest path and longest path algorithms in Python and C++.
• Using scheduling methods and minimum spanning trees.
• Developing and optimizing complex algorithms.

Skills developed:

Graph coloring, Shortest path algorithms (Dijkstra, Bellman-Ford, Floyd), Longest path algorithm, Acyclic graph, Dynamic programming, Scheduling problems (PERT, MPM), Minimum spanning trees (Prim, Kruskal), Linear data structures (Lists, stacks, queues), Tree data structures (Trees, tries, nodes), sets, connectivity, Matrix calculations, capacities, Greedy algorithms, Code optimization, Algorithmic complexity analysis, optimization, Constraint satisfaction, A* algorithm, Python, C++...
Communauté Camunda 8
C8 Open Source Developer
TECH
October 2024 - Today (1 year and 8 months)
As a Camunda expert, I am leading an iso-functional migration project of business processes from FileNet PE to Camunda 8 (c8). FileNet PE is primarily focused on document management with limited workflow capabilities, while Camunda 8 is a modern, cloud-native BPM solution using BPMN for business process orchestration and logging in a NoSQL database. This project optimizes process management in a hybrid environment and contributes to the Camunda open-source community through integration solutions and migration best practices.
Tâches:
• Functional review of existing processes: Analyze FileNet processes, including those evolved for historization and legal requirements.
• Setting up environments:
o Local: Installation of tools (IDE, Docker, Camunda 8, etc.) and necessary dependencies.
o Cloud (AWS): Configuration of services (EC2, IAM, etc.), creation of EC2 instances and management of security roles, automation of tests and deployments via Jenkins.
• Development of processes and workers:
o BPMN process modeling in Camunda, definition of human and automated tasks.
o Development of workers via Camunda APIs, REST services for integration, and an external tasklist.
o Integration with third-party systems (notifications, etc.).

Technical Environment:
Camunda (Modeler, Tasklist, Operate, Identity, Connectors), Zeebe, FileNet PE, Kafka, Spring Boot, Maven, JDK 23, Eclipse, Docker Desktop, C8run, AWS (EC2, AMI, Key Pair, Security Group), PostgreSQL, Keycloak, Kibana, Git, Jolt, Mapper, JSON, Java/FileNet API, gRPC API, Camunda 8 REST API, Elasticsearch, Jenkins, microservices, distributed and event-driven architecture.
