What I'm looking for

I seek senior backend or platform roles where I can design scalable distributed systems, improve observability and performance, and lead engineering practices in collaborative, metrics-driven teams.

I am a senior software engineer with ten years building scalable backend systems and distributed architectures, focused on delivering measurable business impact through reliable engineering.

At QuintoAndar I led implementations such as House Setup and Performance Hub, increasing owner price adjustments by 10.5%, and designed a Pricing Comms multi-channel system using Kafka and the Process Manager Pattern that achieved a 73.4% open rate and drove 13.5% of targeted users to adjust prices.

I architected an asynchronous price suggestion flow handling ~400k requests per day and impacting ~24k daily users by separating prediction pipelines (SQS) and optimizing read tables to reduce latency and eliminate price inconsistencies.

My background includes backend and full-stack roles across e-commerce and SaaS (Node.js, Java, Spring, GraphQL, AWS, microservices, observability and CI/CD), strong applied practices (TDD, Clean/Hexagonal Architecture, SOLID) and experience scaling systems to millions of monthly users.
