Personal details
Victor M.
Summary
With over 15 years of software engineering experience, I have a passion for designing, building, and deploying cloud-based solutions that solve real-world problems in various domains. I am currently a staff software engineer at Zup Innovation, a leading company in digital transformation and innovation in Brazil.
At Zup, I work on the PIX digital payments team, where I improve the quality and performance of a set of microservices that enable instant and secure transactions for millions of users. I use a modern technology stack, such as Kotlin, Spring Cloud, Kubernetes, and AWS, to deliver features, fix issues, and conduct code reviews. I also led a complex performance tests project that resulted in critical findings and optimizations for the PIX product. Previously, I was the software engineer and tech lead of a successful trade-marketing product that was adopted by large industries in Brazil. I have extensive knowledge and experience in microservices architectures and patterns, Java, VueJS, NodeJS, SQL and NoSQL databases, containers, and CI/CD. I am also comfortable with Flutter, React Native, React JS, Angular, PHP, Typescript, and Dart. I am always eager to learn new technologies and best practices that can enhance my skills and the value I bring to my team and organization.
Technical skills
Work Experience
Pix and Cards teams at Itaú Bank
- I led the design and implementation of microservices to support pix payments transactions and credit card flows using different combinations of stacks: Kotlin, Typescript, Spring Cloud, Nodejs, Kubernetes, ArgoCD, Prometheus, Grafana, Redis, and AWS services (SQS, SNS, Dynamo, Lambda, RDS, API Gateway, etc).
- Developed Node.JS lambda functions to address webhook flows that enable 3rd party notifications like Push Notifications.
- Designed resilient solutions to microservices communication by relying on pub/sub approach with SNS, event retries with DLQs redrive, and HTTP retries with feign and circuit-breakers.
- I led code reviews, feature implementations, troubleshooting on production environments, and old feature replacements—especially those that needed performance improvements.
- Provided code refactoring on legacy code to achieve high-level standards of security and architectural patterns
- Helped the PIX product team troubleshoot performance issues and provided solutions that helped transaction time to decrease by 40%.
- Provided reference and support to the recruitment team to interview and evaluate seniors and staff engineers.
- Mentored and helped mid-level engineers, fostering collaboration and increasing team impact.
- Set high-quality standards for the team, applying best practices and improving code quality.
- - “Agenda Reforma Íntima” app - This app is distributed on both platforms (android and iOs) with thousands of users. It works similarly to a daily journal where people can make notes of their daily routines and establish goals to improve their moral values and virtues. It has a gospel approach, with each day having a versicle and other supportive texts of which the user can determine daily goals and later evaluate them. I’m responsible for all its architecture, implementation, and release; to achieve this result. Stack: Flutter, Node.JS, and Firebase (GCP).

- Auta de Souza Online - It is a web platform for online and in-person events like congress for a specific niche. It provides payments integration (pix, cards, billet), reports, ticket emissions, management, etc. I’m responsible for all its architecture, implementation, and release. Stack: VueJS, Node.JS, and Firebase (GCP).
- “Concafras” app - This app was distributed on both platforms (android and iOs). Its mission was to provide an online follow-up of the in-person congress with a timeline of photos, event schedule, etc. I was responsible for all its architecture, implementation, and release. Stack: React Native, Node.JS, and Firebase (GCP).
