Maringá, Paraná, Brazil
I am a Senior Software Engineer with over a decade of experience building scalable, high-performance web applications, now bridging formal Software Engineering with applied Artificial Intelligence. With a postgraduate degree in AI, I offer a rare combination: the reliability of a senior developer who understands architecture and clean code, combined with the innovative capability of Machine Learning and GenAI. My focus is on creating intelligent systems where traditional software meets AI agents, computer vision, and LLM integration. Core Expertise: 🚀 Senior Full Stack Engineering: Extensive background in designing end-to-end solutions using JavaScript/TypeScript (React, Node.js, NestJS, AdonisJS) and Python (Django, FastAPI). I focus on scalability, performance optimization, and robust API design. 🤖 Applied AI & Machine Learning: Moving beyond theory to production-ready AI. GenAI & LLMs: Integration with OpenAI, LangChain, and building autonomous AI Agents. Computer Vision: Implementation using YOLO, HRNet, and OpenCV. Data & ML: Model development with Scikit-learn, TensorFlow, ONNX, and analysis with Pandas/NumPy. ☁️ Infrastructure & Data: Proficient in AWS, database design and optimization (PostgreSQL, MySQL, MongoDB), ensuring that data architecture supports both application logic and AI workloads. My goal is to deliver elegant, robust, and intelligent software — systems that are not only functional but adaptable to the future of AI-enhanced solutions.
Leading the architecture and end-to-end delivery of high-stakes digital platforms, bridging robust software engineering with AI-driven productivity. I specialize in building scalable, modular microservices architectures for complex financial ecosystems, including digital banking, vehicle tagging systems, and investment platforms. My current focus is on accelerating the development lifecycle through an AI-first approach, leveraging tools like Claude Code, Cursor, and GitHub Copilot to ship production-ready code with high velocity and reliability. Core Technical Impact: * Architecture & Scale: Designing resilient systems using Node.js (NestJS), TypeScript, and Python, focused on Domain-Driven Design (DDD) and Event-Driven patterns. * Fintech Expertise: Implementing secure integrations for BaaS (Banking as a Service), third-party APIs, and complex financial flows such as payroll loans and digital accounts. * Cloud & Data: Managing cloud-native infrastructures on AWS and Azure, utilizing PostgreSQL and modern CI/CD pipelines to ensure 24/7 availability. * Product-Led Engineering: Translating intricate business requirements into modular UI components with React.js and Next.js, ensuring a seamless user experience for data-heavy applications.
Engineered high-performance web solutions, focusing on scalability and modernizing the tech stack to support business growth. Frontend Architecture: Designed and implemented modular, reusable UI components using React, TypeScript, and Tailwind CSS, resulting in a consistent design system and faster feature delivery. Backend Stability & Architecture: Architected a robust backend using Node.js and NestJS. Specifically resolved critical failures in Cronjobs and email delivery systems, transitioning the application from an unstable state to a fully reliable, production-ready environment. Critical Integrations: Led the integration of third-party ecosystems (Square for payments and Twilio for communication), automating key business processes and enhancing user engagement.
Key contributor to a high-growth Brazilian iGaming platform, from pre-regulation phase to its strategic acquisition by VBET (April 2025) due to exceptional product performance and market fit. Technical Leadership & Quality: Acting as a technical reference within a 4-squad structure, I drove architectural decisions, established coding standards, and conducted rigorous code reviews to ensure scalability and security. Full Stack Development: Built complex, real-time betting features using React/TypeScript (Redux, Tailwind) for the frontend, Node.js (NestJS/AdonisJS) and Python for the backend, focusing on high availability and low latency. Infrastructure & Compliance: Managed containerized environments (Docker) on AWS and implemented technical requirements for the Brazilian betting regulation framework.
Spearheaded the end-to-end development of two greenfield web applications, acting as the technical lead and architectural focal point. Technical Mentorship: Directly mentored and managed a team of 3 interns, guiding them through code reviews, best practices, and career growth, ensuring successful project delivery and team evolution. Advanced Architecture: Designed scalable backend systems using Domain-Driven Design (DDD) and Event Storming methodologies with Node.js (Nest.js) and Python, ensuring loose coupling and business-logic clarity. Modern Frontend: Architected performant and maintainable user interfaces using React, Typescript, and Zustand for complex state management.
Developed and optimized critical features for a logistics web platform dedicated to streamlining grain exports from Brazil to international markets. Complex Business Logic: Translated intricate logistics and customs requirements into robust software solutions, ensuring the reliability of the export process. Frontend Development: Built dynamic, data-heavy interfaces using React, Redux, and TypeScript, enabling operators to visualize and manage export flows efficiently. Backend & Modernization: Maintained and expanded API services using a hybrid stack of PHP and Node.js (NestJS), ensuring system stability while adopting modern architectural patterns. DevOps Culture: Standardized development environments and deployment processes using Docker, improving team velocity and consistency.
