Lucas Nunes Arvani

Architected and developed a dynamic map-based platform in the Vue.js JavaScript framework to display and cluster pins for each available house or apartment. The interface featured a synchronized list that scrolled to the corresponding pin, enhancing user navigation.

On the back end, I employed Ruby on Rails to manage property data, status updates, and a publishing flow supported by Docker for streamlined deployment. I also enforced quality through comprehensive unit, integration, and end-to-end tests and implemented Sentry for robust error handling and metric collection.

Additionally, this project involved collaborating with stakeholders to gather requirements, designing database schemas, defining the overall architecture, and coordinating with designers to deliver an intuitive user experience.

Led this large-scale effort to migrate a chaotic legacy system handling millions of Brazilian reais in transactions and supporting hundreds of thousands of users.

We rebuilt the system using a modern microservices architecture on GCP, deploying to both production and staging environments via Kubernetes. I developed specialized services and implemented a backend-for-frontend approach to optimize communication among various modules. Additionally, I created reusable front-end libraries that accelerated development across multiple products.

A key challenge was resolving severe data inconsistencies. For this, I enforced strict validation rules and set up two-way synchronization, ensuring the new services stayed in sync with the legacy system. I also established Kubernetes deployment pipelines for robust CI/CD. Alongside another lead, I supervised a team of four developers, collaborated with designers, and engaged stakeholders to define requirements for this critical modernization of a high-revenue, high-traffic platform.
