About Dac-An

Centralien Engineer | Automation & Optimization of business processes with AI

As a graduate engineer from Centrale, I help companies and entrepreneurs who want to gain operational efficiency by automating non-value-added tasks and optimizing their business processes through the development of custom internal tools.

My conviction: a good tool is not coded in haste. That's why each mission begins with a2-week audit phasededicated to deeply understanding your operations, identifying real friction points, and capturing the actual problem, beyond apparent symptoms. This scoping phase is key to a solution that sustainably integrates into your business rather than becoming just another tool to maintain.

Once the problem is identified, I design and developcustom internal toolstailored for your teams: workflow automation, business interfaces, integrations between your existing tools, data processing… The objective is always the same: free up human time from repetitive tasks to reinvest it where it truly creates value.

I notably leverageClaude Codeto accelerate the development phase, allowing me to deliver faster while maintaining a high level of quality and maintainability of the produced code.

My approach is particularly suited forSMEs, startups, and entrepreneurswho feel that their teams (or themselves) are spending too much time on manual and repetitive tasks, and who want a pragmatic solution tailored to their reality.

Let's discuss your processes and boost your efficiency.
