I am a goal-oriented Full Stack Software Developer with about 2.5 years of React-focused experience in the Telecoms and Health Insurance sectors in the Netherlands, complemented by freelance work across E-commerce, Health Insurance and Online Gaming. I recently completed an intensive Full Stack Development bootcamp with Ironhack to sharpen modern front-end and back-end skills, and I’m eager to apply my training to React full-stack projects to help your company grow and streamline operations. I thrive in agile teams and enjoy delivering high-quality, visually appealing interfaces and robust workflows. I have hands-on experience integrating complex authentication and data flows (including DigiD integration for Lifetri), real-time updates, and legacy data migration while keeping customers engaged and confident in using the platform. I’m looking for roles where I can contribute to fast, reliable releases and collaborate closely with clients to meet their requirements.
