Description

The backend is the part of the system nobody sees and everybody remembers when it breaks. My job is to make sure it doesn't. I build server-side architectures designed to last: organised code, separated concerns, data modelled properly from day one, and room to grow without a rewrite. I work primarily with Laravel, but also with Node.js and Spring Boot where the context calls for it.

What's Included

• System Architecture: Defining the project's technical structure, separation of concerns, domain modelling and technology choices justified by the problem rather than by fashion.

• Multi-Tenant Systems: SaaS platforms with per-client data isolation discriminator column, schema-per-tenant or dedicated database, depending on the isolation level required.

• Modular Architecture: Plugin systems that enable and disable features per client or per plan, with no code changes and no separate deployments.

• Asynchronous Processing: Queues, scheduled tasks and background processing for heavy operations, bulk sends and integrations with slow external services.

• Security and Access Control: Authentication, granular role and permission-based authorisation, endpoint protection and audit logging of sensitive operations.

• Legacy System Maintenance: Recovery, refactoring and evolution of existing systems, including cases where the documentation no longer exists.

Technologies

• Frameworks: Laravel (primary), Node.js and Spring Boot.

• Databases: MySQL, MariaDB and PostgreSQL, including PostGIS for geospatial data.

• Infrastructure: Docker, CI/CD pipelines, Linux server administration and cloud hosting.
