Freelancer profile translated to English.
Back to original languageAbout Taher
Based in Aix en Provence, mobile in the Bouches-du-Rhône/Provence region and Ile de France.
Invested, rigorous, and with a solid technical background, I secure the delivery of complex infrastructure and information system projects in demanding, political, or multi-stakeholder environments.
Thanks to the experience gained on large-scale projects, I am able to compensate for the absence or weakness of key roles such as Product Owner, architect, or technical expert to maintain the quality, consistency, and pace of the project.
I deliver concrete and measurable results:
- Systematic delivery on time, even on projects with high technical and political stakes.
- +50% internal time savings through the automation of project tools (VBA).
- Operational reinforcement for missing roles: taking on the role of PO, architect, or technical expert in parallel with project management without exceeding the initial workload.
- Management of a strategic program (provisioning of the infrastructure hosting the 7 IS managing 11 million gas meters), delivered on a fixed date after 2 years of visibility.
- Skill development of teams not mature in agile, while ensuring the delivery of an IS in 3 months.
- Implementation of a containerization offering: 18 months of project delivered on time, budget respected, no overruns.
My objective: to transform complexity into tangible results, with commitment, seriousness, and a real ability to unite in sensitive contexts.
