I am a Senior Backend Engineer with 10+ years of experience, specializing in Java, Spring Boot, and AWS. I don't just write code; I engineer resilient systems that handle millions of requests.
Most recently at QuintoAndar (LatAm's largest PropTech), I architected a solution for the Pricing Engine that reduced latency by 90% (from 3s to 200ms) under heavy load. My background also includes 6 years in high-volume E-commerce (Riachuelo), dealing with critical checkout flows.
I am looking for Senior opportunities where I can apply my expertise in Microservices, Event-Driven Architecture, and Performance Optimization to solve complex business problems.

- Setup & Performance Hub: Led the implementation of the ‘House Setup’ and ‘Performance Hub’ features, resulting in a 10.5% increase in price adjustments by rental owners with active tasks, by engineering a high-performance, non-blocking reactive backend (using Java's Project Reactor: Flux/Mono) to power a unified flow that guides users to optimize pricing and other key factors to make house listings convert faster.
- Pricing Comms Strategy: Developed and implemented the ‘Pricing Comms’ strategy for overpriced properties, leading 13.5% of targeted users to make a price adjustment and achieving a 73.4% open rate, by architecting a scalable multi-channel system using Kafka and the Process Manager Pattern to manage stateful comms triggered by low listing demand.
- Async Price Suggestion Flow: Led the architecture and implementation of an asynchronous price suggestion flow, impacting an average of 24k daily users (~400k requests per day) by eliminating price inconsistencies for users and drastically reducing API latency, by separating the prediction (via SQS) from the AI suggestion and saving the data in a new, optimized read table.
