Serhii F.

Senior Angular Developer and Frontend Engineer with 8+ years of experience building scalable web applications, complex product interfaces, and reusable design systems with Angular, TypeScript, React, and Storybook. I help startups and product teams build, improve, and scale frontend applications - from defining architecture and component structure to hands-on implementation, performance optimisation, and technical leadership. My strongest areas are: • Angular application architecture and development • Frontend architecture and technical decision-making • Reusable component libraries and design systems • Storybook and UI engineering • Complex SaaS, dashboards, and business applications • TypeScript, RxJS, React, and modern frontend development • Ionic for cross-platform web and mobile applications • API integration, authentication, RBAC, and real-time data • Performance optimisation, bundle size, and frontend scalability • Technical leadership, code reviews, mentoring, and engineering standards A major part of my experience is building reusable frontend foundations rather than only implementing individual screens. I have architected and maintained Angular component libraries with Storybook, standardised UI patterns across products, and built application-builder workflows on top of reusable components. In one product environment, this reduced feature development time by up to 30%. I’m comfortable joining an existing product and improving its architecture, taking ownership of a new frontend from the ground up, or acting as the senior engineer responsible for frontend technical direction. I work best with startups and product teams looking for a long-term engineering partner who can combine hands-on development with architectural thinking and technical ownership. If you have an Angular codebase, a growing product, or frontend architecture that needs to scale, invite me to your project and we can discuss the technical approach and next steps.
