What I'm looking for

I’m seeking to deepen my expertise in cloud architecture, DevOps, and information security to protect data in Mali.

At Orange Mali, I designed and built LicenseHub, an internal platform for managing software licenses, purchase requests, and training needs. I added configurable email and SMS expiry reminders, LDAP sign-in, and role-based permissions.

I deployed LicenseHub on a company production server, configuring Nginx, a Galera database cluster, and Elasticsearch with Kibana. I also built a scheduler connected to Apache Airflow for running Bash, HTTP, SQL, or Docker commands.

At Ricash, I developed a secure e-wallet module for a money-transfer application, tracking transactions in real time and managing wallet and payment states. I implemented ACID transactions and automatic reconciliation within a Docker-based microservices architecture.

I also created Nexus AI, an open-source desktop IDE where AI coding agents work in parallel on isolated project copies. My work includes a local team bus, task assignment to prevent file conflicts, and security measures including process isolation and an optional Linux sandbox.
