I develop end-to-end full-stack web applications for business automation and SaaS platforms using Next.js, React, TypeScript, Node.js, Python, PostgreSQL, and REST APIs. I build scalable frontend features and backend services while owning the lifecycle from requirements gathering and solution design through deployment and production support.

I design modular architectures and integrate payment gateways, ERP platforms, NF-e services, and third-party APIs. I also developed a Meta WhatsApp Cloud API automation platform that delivers more than 140 personalized client documents each month and removes repetitive manual processes.

I delivered full-stack web applications for retail, manufacturing, beverage distribution, and professional-services clients using Next.js, React, TypeScript, Angular 16, Node.js, Python, and PostgreSQL. I built reusable UI components, responsive interfaces, scalable REST APIs, dashboards, and custom ERP systems for inventory, production, finance, and order management.

I created Python and WhatsApp Cloud API integrations for communications and workflow automation, as well as Puppeteer browser automation solutions that reduced manual work. I collaborated with stakeholders on requirements, estimates, technical solutions, and production-ready delivery.

I built a full-stack web platform from scratch using React, JavaScript, Python, PostgreSQL, and REST APIs. I led requirements gathering, architecture, backend and frontend development, database design, deployment, and production support.

I designed relational data models and processing routines for scalable daily operations. I also built Python automation pipelines to extract, validate, and process XML documents, reducing manual processing time by more than 50%.

I developed and maintained React interfaces and Python backend services for logistics operations and business-critical applications. I built REST APIs, relational database models, and backend services with emphasis on scalability, reliability, and data integrity.

I implemented authentication, authorization, and role-based access control to strengthen security and user management. I also delivered integrations and automation solutions that replaced manual processes, reducing processing time by more than 50%.

I developed and maintained full-stack business applications using Python, SQL, REST APIs, and customer-focused software enhancements. I integrated WhatsApp APIs and third-party services to automate workflows, improve communication, and reduce manual work.

I optimized database models, SQL queries, and data-processing routines for performance, reliability, and data integrity. I worked directly with clients and internal teams to analyze requirements, design technical solutions, and deliver production-ready features.

I developed and customized TOTVS ERP solutions using ADVPL, supporting finance, operations, inventory management, and business workflows. I created backend routines, system integrations, and data-exchange processes between TOTVS ERP and external business platforms.

I optimized SQL queries, database operations, and data-processing routines to maintain data integrity and reliability. I collaborated with clients to analyze requirements, customize ERP modules, automate processes, and deliver solutions aligned with operational needs.
