Silent Spring Institute is a mission-driven scientific research organization dedicated to uncovering the environmental causes of breast cancer. Technology is moving fast and so already developed apps must be up to par to recent development. Silent Spring Institute wanted to resolve a plethora of issues with their previously developed, using React Native, mobile apps. Flutter was proposed in order to modernize the mobile apps and resolve all of their issues as well as hugely improving the UX and even bringing new features, that previously posed a challenged to be implemented, to life. My main responsibilities included: - Architect the new Flutter solution to smoothly migrate all the features and existing users from the React Native apps. - Development of the new Flutter apps, maintaining the same look-and-feel for unobstructed transition for the old users, while making necessary UI/UX improvements. - Development of new features that previously posed a challenged to be implemented. - Development (with occasional assistance from another dev) of the new API using Fastify to transition away from tight dependency and limitations of AWS lambda. This allowed for a more solid architecture and more future-proof implementation. Feedback for the new apps showed overwhelmed excitement for the capability to deliver features much faster, bring long awaited features to life as well as quicker problem resolution due to leaner architecture.

BookHero is a mobile app aiming to bring fantastic and mesmerizing children stories to life with the usage of ChatGPT! Developed mostly by me, with the occasional help of another developer, it has been a quite enjoyable project making good use of ChatGPT for story generation and Stable Diffusion for story image generation. A lot of focus was put on a smooth user experience and most of the designs were provided by the client. Main responsibilities included: - Architect a scalable and performant solution to quickly bring the mobile app to the market during the AI market uptrend. - Ensure best practices in security and workflow. The app includes a paid subscription. - Suggest technical solutions and discuss pros and cons of alternatives with client.
