The heart of an application beats on the backend. This invisible yet vital structure must be built on security, performance, and sustainability. Alongside my expertise in PHP and Laravel-based systems, I work with a "zero error" principle derived from my experience in financial technologies. In the e-commerce systems I have developed to date, I have successfully managed massive structures including complex payment integrations, shipment tracking systems, and inventory synchronizations. In my backend development service, I aim for the highest standards at every stage, from database optimization (MySQL, PostgreSQL, Redis) to API design (RESTful, GraphQL). With my identity as a software architect, I approach backend processes as system design rather than just writing code. Whether building microservices or monolithic structures, I implement load balancing and caching mechanisms necessary to prevent the system from collapsing under high traffic. In my Web3 projects, I established the bridge between smart contracts and the backend, ensuring secure processing and storage of blockchain data. For me, security is not an option; it is a necessity. While creating top-level shields against threats like SQL injection, XSS, and CSRF, I meticulously apply financial data security standards (GDPR, KVKK compliance). By transforming complex business logic into clean, documented, and scalable backend code, I fortify the technological backbone of your project.
