Junior React Native Developer, iOWNA
November 2024 – present
At iOWNA, a digital platform for healthcare providers and patients built on a universal React Native framework, I develop new features, resolve technical issues, and participate in design discussions. I also perform cross-browser and cross-device testing to ensure functionality and maintain the existing codebase. Working closely with a team, I've gained significant mobile development experience in a short time and have been productive from day one. Working in sprints has enhanced my ability to plan tasks effectively, set realistic timelines, and manage my time efficiently.

Website developer, iOWNA
August 2024 – November 2024
I designed and built a responsive website for iOWNA to make the user experience smoother and attract more clients. Using Next.js, Tailwind CSS, and TypeScript, I created a site that looks great and works well on any device. The main goal was to keep things user-friendly and visually appealing, so visitors enjoy their time on the site and are more likely to convert into clients. I worked closely with the marketing and product teams to make sure the site supports iOWNA's goals and helps bring in new business.
