- Context
- A critical module had to migrate while the banking integrations were running in production. No outage window available.
- What I did
- Led a team of four engineers, split the migration into verifiable increments, coordinated releases across web and mobile.
- Outcome
- Migration delivered in six weeks, with no interruption to the banking integrations.

El Mehdi BenaneSoftware engineer
Founder of Tari Software · Paris, France
I work with companies whose software is already business-critical. I get it back in shape to run another ten years, without a rewrite and without stopping production.
Six years on systems where a mistake shows up immediately. An online bank, a cybersecurity suite, terabyte-scale financial pipelines. None of them could be switched off to be repaired. That is the only thing they had in common.
Tari Software comes from that. Most companies do not need everything rewritten. They need someone willing to read the code that exists, understand why it is the way it is, and move it forward without breaking what works.
I work in French and English, from Paris, for clients in France and elsewhere.
Engagements
What I worked on, and what came of it.
Four engagements, by the problem and the outcome. Employers are named. The details of their systems stay with them.
- Context
- Python financial data pipelines that no longer kept up with the volume, and infrastructure that had to reach SOC 2 standard.
- What I did
- Rewrote the most expensive processing paths, rebuilt the AWS infrastructure in Terraform, set up CI/CD and ran the compliance work.
- Outcome
- Pipelines that keep up with the volume again, infrastructure that can be rebuilt from code, and the SOC 2 compliance work carried through to the end.
- Context
- Figma mockups and nothing behind them: a secure production application was needed, wired into the tools already in use.
- What I did
- Built the application end to end, secured the backend, integrated OpenAI, Teams and Jira. Mentored the junior developers on the project.
- Outcome
- Application shipped to production, and a team able to move it forward without me.
- Context
- An IAM suite needed to understand who had access to what, starting from raw, high-volume entitlement data.
- What I did
- Designed and built an RBAC analysis and role-mining engine, then a backend able to absorb security events asynchronously.
- Outcome
- Delivered end to end, from design to production. It is a suite sold to clients, so there are no public figures to give here.
