I'm Felix Ajibola — a backend-focused full-stack engineer building secure, multi-tenant platforms for property management, maintenance, HR, and aviation operations. I specialise in API architecture, workflow automation, access control, auditability, and production-ready delivery.
I turn complex operational processes into dependable software. My work spans backend architecture, data modelling, multi-tenancy, role-based access, PostgreSQL Row Level Security, document workflows, and responsive interfaces.
I have built and supported systems across property and service-user management, aircraft and industrial maintenance, enterprise HR, hospitality, and real estate. I work closely with domain experts to translate real operational requirements into secure, maintainable products.
