Leading the Sales Ops Tribe we faced a challenge on the internal organization and optimization of commercial teams at Loft. Meanwhile we had the teams structure setup on ops, we were facing problems to generate consistent analytics data and to put in place the productivity incentives for the commercial teams into the backend / backoffice systems. Integrating with Salesforce as the main tool used by the internal Loft ops teams, we were able to integrate transactions and operations from website to internal backoffices / Salesforce given a consistent view for operations and management, so we could implement the correct incentives to scale up sales. We faced tech challenges with Salesforce integration and development that needed concrete solutions on the Salesforce tech context, like setting up a release pipeline from github (avoiding coding inside the Salesforce platform directly) and decoupling systems from Salesforce using platform events, which improved substantially development productivity inside the Salesforce platform (cycle time from 2 months to 2 weeks).

As we identified challenges to improve the Salesforce development cycle time we managed to reorganize our architecture so we minimized the amount of work needed inside the Salesforce platform using external services and platform events as the main integration solution. With this in place we managed to achieve an overall 2 day cycle time on the Sales Ops teams, despite Salesforce. With that solution we were able to put in place the new incentive program for the commercial teams that directly impacted sales results. Mostrar menos

As technical leader of the Sales Tribe, I've been directly envolved on the project we called Visits Revamp. Visiting is one of the main commercial process for real state transactions and Loft was going through a great change on the operations of this process while the systems under the hood were difficult to evolve and maintain. The current context included difficulty to track transactions, missing transactions impacting customer experience directly and difficulty to apply analytics tools on data generated by the process. We were able to strangle the legacy systems while putting in place a system that focused on consistency and ease of operation. This included correctly managing of async transactions with proper idempotency implementation on all endpoints, ensuring we have consistent and detailed data for all the process all the time. After the intervention, we were able to reduce to zero the impact on customer experience while, at the same time, allowing experimentation of process evolutions and keeping data consistent for analytics and troubleshooting purposes.

This centralized identity created a momentum for sharing a single, simple to generate and use identity for earch customer that were shared across all processes inside Loft systems. From marketing campaigns, to transactional operations and from communications and (including red customer), we became able to identify each customer uniquely. This gaves us at Loft the abality to use analytics tools to identify and tackle the main issues on customer experience, with strong impact in targeted marketing and quality. Mostrar menos
