📦 API EXPERT – TypeScript & NestJS At Bashroom, I specialize in API development using TypeScript, with a strong focus on the NestJS framework. Formerly an expert in Java and JavaScript, I naturally transitioned to the TypeScript ecosystem to build modern, modular, and high-performance backend solutions. With a solid background in IT and experience designing complex systems, I ensure every solution delivered is robust, scalable, and meets the highest standards of reliability. 🛡️ IAM / APIM SPECIALIST I am also an expert in configuring and customizing IAM solutions with Keycloak and APIM solutions with Gravitee. My expertise allows me to deliver secure, tailor-made solutions that precisely meet each client's specific needs while adhering to the latest cybersecurity standards. 👾 GAME DEVELOPER On a personal level, I am passionate about game engines and particularly enjoy creating open worlds. These types of games require high performance, so I leverage both Godot and Rust to surpass typical limitations and deliver unique gaming experiences that are both smooth and immersive.
