Lotto Logic — SaaS engineering

Symfony · PHP · MongoDB · Git CI · AWS

Improved release confidence and backend maintainability inside a live SaaS product with ongoing delivery pressure.

Challenge

The platform needed safer releases and cleaner backend structure without disrupting a live SaaS roadmap.

Result

Releases became more predictable, backend changes were easier to ship with confidence, and the codebase became easier to extend without compounding legacy risk.

What I did

Added PHPUnit coverage to key backend paths with the highest regression risk
Implemented CI checks around build and release workflows
Refactored legacy backend modules into cleaner reusable components
Improved performance in slow backend areas that affected day-to-day delivery

Key outcomes

Introduced PHPUnit coverage around critical backend flows to lower regression risk during releases
Implemented Git-based CI pipelines so deployments were more repeatable and easier to trust
Refactored legacy backend code into smaller reusable modules to reduce maintenance friction
Improved backend performance in production while preserving delivery cadence
