At illumy, we built a hypercommunication app that integrates voice, messaging, email, and SMS into one platform. Using Next.js and React for the frontend, and GraphQL for efficient data querying, we developed a fast, seamless user experience. The backend, powered by Kotlin and microservices, utilized relational, non-relational, and graph databases. Internal communication was handled via RabbitMQ, and gRPC ensured fast, reliable connections with web and mobile apps, maintaining API response times under 150ms for optimal performance.
At this project goal was to migrate the company's e-commerce platform to Next.js to significantly improve performance and user experience. My solution involved leading the migration, focusing on optimizing website load times and streamlining workflows. This resulted in a 500% improvement in load times and a 150% annual increase in conversions. Additionally, I introduced a code review process that reduced production bugs by 30%, and collaborated across teams to enhance branding and SEO, driving a 30% increase in organic traffic.
At illumy, we developed a mobile app that seamlessly integrates voice, messaging, email, and SMS into a single platform. Using React Native for the frontend, we ensured a fast, smooth user experience across devices. The backend, powered by Kotlin and a microservices architecture, supported both relational and non-relational databases for efficient data management. Internal processes were managed with RabbitMQ, while gRPC enabled fast, reliable communication between the mobile app and backend services, maintaining response times under 150ms for optimal performance.
