About me
EXPERIENCE
Lead Software Developer
MacroTerminalI worked on a trading analytics platform designed to support day traders with real-time market insights. My responsibilities included building and maintaining data pipelines to process financial metrics such as option Greeks (Delta, Gamma, Theta, Charm, Vanna) and price data. To ensure low-latency delivery, I developed Python-based services that performed complex calculations and generated over 700 different chart variations, considering multiple tickers and expiration dates. The computed data was cached using Redis and distributed through a Redis Pub/Sub mechanism to the main server. On the frontend, we implemented real-time updates via WebSockets, ensuring traders received instant, up-to-date visualizations with minimal system load, thanks to efficient caching strategies. Additionally, we explored machine learning techniques, such as Random Forest models, to enhance data analysis and predictive capabilities within the platform.

Regulatório MaisAs Lead Developer, I was responsible for architecting and implementing high-volume data processing systems to generate regulatory reports for Brazilian financial authorities (e.g., BACEN). We handled millions of banking transactions provided in large CSV files (+15 million records), which required efficient data pipelines. To achieve this, I designed a batch processing flow using AWS SQS for distributed task management and PostgreSQL as the core data store. We optimized database structures and queries to support complex aggregations and reporting with a focus on performance and scalability. This project strengthened my expertise in handling big datasets, building reliable event-driven systems, and ensuring data consistency in large-scale applications.
Fullstack Developer
Convem StoreI worked across the TypeScript ecosystem, developing scalable solutions with React on the frontend and Express on the backend. In terms of infrastructure, I gained solid experience with AWS services such as DynamoDB (NoSQL), PostgreSQL (relational database), API Gateway, and EKS for container orchestration. I also contributed significantly to code organization and project scalability, creating templates and standardized setups for Lambda functions, Express microservices, and Infrastructure as Code using tools like AWS CDK and Terraform. Additionally, I collaborated in building event-driven services with AWS SQS and Lambda for asynchronous processing and distributed workloads.
Fullstack Developer
Via Dupla ArquiteturaA freelance where a homepage and a system were developed for two architects from my city. They wanted something that represented them but at the same time could add new projects that would serve as a kind of portfolio for future new clients.
Projects
Real-time system for day traders, processing price data and financial metrics (Greeks) with Python services. Generated 700+ chart variations, used Redis for caching and Pub/Sub, and delivered instant updates via WebSocket. Included ML models like Random Forest for enhanced analysis.

Via Dupla
A landing page and system for two architects who have access to an administrative page where they can add, edit or delete projects. It was developed with nodejs in the backend using mongodb as a database and Google drive to store the images. In the frontend, the ejs template engine was used along with css and vannila js.

In this project I made my portfolio, showing a little more about my professional side. The purpose of this project is to add value to my professional image. It was
developed with NextJs along with tailwindcss in the frontend, and sanity was used as a CMS for the page content.
