Project History
Healthcare App for iOS and Android
This project involved developing a cross-platform health management app using React Native to help users improve their blood pressure and related health issues. The app provides personalized habit suggestions and connects to external blood pressure monitors via Bluetooth Low Energy (BLE).
I contributed across the full stack, from front-end and back-end development to infrastructure provisioning with Terraform. I also made upstream contributions to React Native libraries, extending support for previously unsupported iOS HealthKit and Android Health Connect. I collaborated proactively within a lean, Agile team environment.

CRM Development
Led a project to migrate a legacy monolithic server-side application with RESTful APIs to a modern microservices architecture using a GraphQL-based BFF and an event-driven approach with gRPC, RabbitMQ, and Kafka. Leveraging my years of experience with GraphQL, I guided the team by demonstrating best practices, onboarding members, and driving the architectural transition. The migration improved performance, enhanced security, and provided a significantly better user experience.
