Software Engineer – Frontend Developer (ReactJS, UI/UX Expert)
My name is Boris Civcic, a passionate and seasoned Frontend Developer with over 13 years of professional experience in software development, and more than 8 years of deep specialization in ReactJS. Throughout my career, I have consistently delivered high-quality digital solutions, combining technical precision with a strong sense for user interface and user experience (UI/UX) design.
My work is rooted in creating interfaces that are not only performant and scalable, but also intuitive, accessible, and visually compelling. I bring a user-centered mindset to every project, ensuring that the products I help build offer meaningful and seamless experiences.
Over the years, I’ve contributed to and led the development of a wide range of applications, from enterprise-level platforms to consumer-facing products. I’m known for my ability to collaborate effectively with cross-functional teams—designers, product owners, and backend engineers—and communicate clearly with stakeholders and clients.
Key strengths include:
- Expert-level ReactJS development with extensive hands-on experience in hooks, state management (Redux, Context API, Zustand), and component-based architecture.
- Strong understanding of UI/UX principles, usability best practices, responsive design, and accessibility standards (WCAG).
- Focus on clean, maintainable, and scalable code, following modern development practices such as code reviews, testing (Jest, RTL), and performance optimization.
- Proficiency with design systems, component libraries (e.g., MUI, Chakra, Tailwind), and tools like Figma and Storybook.
- Solid backend foundation with experience in Node.js, Express, and MongoDB—having built full-stack applications from scratch, showcasing my versatility and problem-solving abilities.
From 2017 to 2021, I co-founded and operated a dedicated school focused on teaching frontend development skills. Alongside my colleague Aleksandar, we provided comprehensive programming classes tailored to a diverse range of learners, from students and beginners to older adults. Our curriculum covered essential technologies such as JavaScript, HTML, CSS, ReactJS, and TypeScript. Our school was equipped with a professional office space, where we delivered hands-on training and fostered a supportive learning environment. This experience is particularly important because it demonstrates my ability to effectively impart knowledge to others, empowering individuals with the skills needed to excel in the rapidly evolving tech landscape.

Boris has been a long time member of the team from the beginning, and develops a react based frontend from scratch for us. He has owned the end to end system from day 1, and can thrive in fast paced, early stage startup environment. He is a hard worker, and will go above and beyond to add value. He has invested in learning on areas that he never worked on before, like browser push notifications or webrtc, and successfully delivered outcomes that are running in production reliably. I am grateful for your work and wish you all the best in the future endeavors. Boris would be an asset to every team and I highly recommend that, based on our full time engagement for over 18 months.
