Full Stack Developer | Software Engineer | Back-end Developer | NodeJS | Python | JavaScript

• Engineered critical features for 3S Checkout, a high-availability cloud POS and food service management system, efficiently processing over 1.5 million orders monthly.
• Optimized microservices architecture to support large-scale, concurrent operations for major enterprise clients, including Burger King, Outback, KFC, and Pizza Hut.
• Integrated legacy systems, self-service kiosks, and delivery hubs, centralizing the data flow and significantly reducing synchronization bottlenecks across the entire operation.
• Developed dynamic back-office dashboards and scalable RESTful APIs, streamlining centralized inventory and menu management for more than 1,500 stores.
• Worked as part of the Platform team across Back Office and Store/POS systems, developing and maintaining internal libraries, developer tools, infrastructure solutions, and GitLab CI/CD pipelines.
• Implemented OpenTelemetry instrumentation and centralized logs, traces, and metrics using Grafana and Datadog to support troubleshooting and support operations for more than 1,500 stores.

• Relevant Skills: Python, TypeScript, React.js, SQL, Unit Testing, JavaScript, Git, AWS, Redux.js, AWS SQS, Postgres, OpenTelemetry, Grafana, Datadog, Docker, CI/CD, Flask, Microservices, Software Architecture, System Design, Unit Testing, Software Architecture, System Design, Microservices, and CI/CD.

• Managed and optimized control systems, IoT solutions for embedded devices, and external system integrations, with the platform integrating and managing data from more than 50,000 IoT devices.
• Developed management and control systems that elevated operational efficiency, reducing bottlenecks in key processes and streamlining performance reporting.
• Designed and implemented event-driven IoT solutions managing data from more than 50,000 devices, using MQTT, AWS IoT Core, and AWS Lambda for asynchronous telemetry ingestion and processing.
• Integrated external systems in complex environments, coupling hybrid technologies and ensuring compatibility without compromising the performance of IoT platforms, applications, and Web 4.0 servers.
• Acted as one of the two leads and main decision-makers for the entire Eonix platform, working with clients, investors and stakeholders to define what to build and how.
• Delivered end-to-end an LLM feature that lets non-technical clients trigger industrial processes by voice or text, in the app and through a WhatsApp chatbot; only about 2% of requests needed a second attempt.
• Designed the LLM as a proxy that only returns events, validated against a mapped event catalog with all-or-nothing execution, because some plant equipment affects workers' physical safety.
• Implemented remote control for industrial plants: an EC2 service publishes commands to dedicated MQTT topics, and AWS IoT Policies restrict each plant to its own topics.
• Connected on-site equipment to the cloud through a local Mosquitto broker, reading Modbus devices locally and forwarding buffered telemetry to AWS IoT Core.

• Instrumented the platform with OpenTelemetry, tracin

• Relevant Skills: Django, TypeScript, React.js, SQL, Express.js, Unit Testing, Node.js, JavaScript, Git, AWS, Python, MQTT, Redux.js, Fastify, AWS SQS, Postgres, OpenTelemetry, IoT Core, DynamoDB, Next.js, Nest.js, Docker, CI/CD Unit Testing, CI/CD, and Django REST Fr

• Developed loyalty systems for gas stations, logistics management solutions, IoT integrations, and applications within a B2B2C platform used by more than 200 companies in Brazil.
• Implemented asynchronous file and report processing using AWS SQS and AWS Lambda, with queue-based processing and long-polling status tracking.
• Executed integrations with IoT devices in critical environments, providing real-time data and enabling more accurate decision-making by operational managers.
• Created interfaces and features focused on user experience, resulting in greater usability and reduced support tickets, and implemented CI/CD pipelines to optimize system delivery.
• Collaborated actively with cross-functional teams to deliver robust and scalable solutions aligned with specific client needs and the company's technical strategy.

• Relevant Skills: SQL, React Native, Happi, Node.js, React.js, JavaScript, TypeScript, Flask, CI/CD, Express.js, Unit Testing, Git, AWS, Python, Kafka, Postgres, IoT, PostgreSQL, AWS SQS, AWS Lambda, Amazon ECS, GitFlow, and Docker.

• Contributed to the development of a real-time industrial operations monitoring and energy optimization system processing more than 30,000 measurement data records per day.
• Worked with an event-driven architecture using RabbitMQ, AWS SQS, and AWS Lambda, with microservices consuming dedicated queues and processing data asynchronously.
• Implemented energy optimization strategies that reduced resource consumption by approximately 12%, generating millions of reais in savings on energy from natural gas, electricity, solar sources, and fossil fuels across large industrial plants.
• Contributed significantly to the reduction of greenhouse gas emissions, aligning the system with sustainable practices and the industry's
ESG goals.
• Applied data science-based approaches to guide operational decisions, promoting significant efficiency gains and accelerating digital transformation within industrial environments.

• Relevant Skills: SQL, Node.js, Python, Django, Django REST Framework, JavaScript, Angular, React.js, Unit Testing, Microservices, Express.js, Typescript, Git, RabbitMQ, ActiveMQ, MogoDB, NoSQL, Postgres, IoT, AWS SQS, AWS Lambda, Amazon ECS, AWS ALB, and Web 4.0.

Bachelor's degree in Systems Analysis and Development.
