Summary
I am a Senior Front-End Engineer with over 7 years of experience in software development. I enhance digital experiences at Nike by developing and implementing front-end solutions that align with internal product requirements. I’ve designed and built internal CMS products that help employees advance in their careers, and I take pride in creating solutions that make a difference.
Before joining Nike, I worked as a Full-Stack Engineer at PayPal, focusing on improving the B2B and tenancy experience for business customers. I collaborated with other engineers to create advanced tools that optimized our services and elevated the technical expertise of my colleagues. For example, I implemented a feature set that reduced page load times by 35%, improved user experience, and cut customer support tickets by 20%.
Throughout my career, I’ve worked with technologies like JavaScript, React.js, Node.js, Express.js, AWS, and more, developing full-stack solutions that are efficient, scalable, and user-friendly. I’ve also built and maintained systems in cloud environments, focusing on deploying robust and easy-to-use SaaS solutions. My experience ranges from enterprise software to start-ups, and I always aim to deliver real results.
I’m passionate about creating products that exceed expectations. One of my key achievements includes implementing continuous integration practices that cut deployment times by 40%, enabled quicker release cycles, and boosted team productivity. I also led a project that resulted in a 25% increase in user engagement through UX/UI improvements.
I’m always looking to grow my personal and professional network. Feel free to connect via LinkedIn or contact me directly at contact@sebsv.com.

3D Printing, Content creation, Open source projects
In my free time, I enjoy pursuing a few creative and technical hobbies outside of my professional work as a software engineer. One of my main interests is 3D printing - I've designed and 3D printed a variety of custom parts and objects, from functional household items to prototypes.
Through this hobby, I've developed skills in 3D modeling, slicing software, and troubleshooting various printing techniques and materials.
My interests in 3D printing and open-source development reflect my broader curiosity and drive to continuously learn, create, and share knowledge. These hobbies allow me to explore my technical passions outside of my day-to-day software engineering work.
