Trendify • Freelance
Dec 2021 - Apr 2026 • 4 yrs 4 mos
I have been working with Trendify since the beginning of the project. My role has been to maintain, improve, and update the website whenever new requirements or changes were needed. Whenever the client requested new features or modifications, I implemented them and deployed the updates to keep the platform running smoothly. I consistently maintained the website to keep it stable and up to date. Whenever new versions of React.js or Next.js were released, I upgraded the project to the latest versions to maintain compatibility, performance, and security. My work with Trendify included ongoing development, fixing issues, improving functionality, and keeping the codebase aligned with modern development standards. Through this long-term collaboration, I helped keep the platform reliable, updated, and ready to scale as the project continued to grow.
