What I'm looking for

I’m looking for a role where I can own system design and delivery end-to-end—building reliable backends for data-heavy SaaS, automating operations, and shipping secure features that move the product forward.

I’m a full-stack software engineer specializing in data-heavy SaaS systems, backend reliability, and automation. I focus on ownership, system design, and delivering end-to-end solutions—from database to user experience.

At Drivago, I designed and built a cross-repository training platform across 7+ services, enabling secure multi-device usage and concurrent access without session conflicts. I integrated payment gateways (Konnect, Flouci), owning the full payment lifecycle and automating subscription billing across thousands of transactions.

I also lead production incident resolution for 500+ client agencies by rapidly reproducing and debugging cross-platform issues, and I manage Linux deployments with Nginx and PM2. I build automation using cron jobs, strengthen authentication and security (magic-link login, OAuth, real-time fraud detection), and migrate core repositories (Angular v14 → v19) to standardize architecture and support RTL/LTR.
