Breno – React, Angular, Typescript

There were two projects Breno worked on: one was a React Native fintech mobile app with AWS-based microservices, and the other was an AI platform for modernizing legacy codebases.

• Led full-stack development of React Native mobile app with plugin architecture and AWS Lambda microservices.
• Architected cloud infrastructure and implemented CI/CD pipelines.
• Mentored engineers across all seniority levels.
• Led Angular micro-frontend implementations using Single-SPA.
• Established BFF architecture standards with Nest.js.
• Championed WCAG compliance initiatives.
• Worked with MongoDB and Atlas for cluster management, including large collections under moderate-to-heavy load.

A large-scale agtech B2B/B2C portal built on a microservices architecture, connecting farmers/growers to a major agricultural business. The platform manages the full lifecycle of agricultural bonification programs, sales data, licensing agreements, volume operations, and multi-stage approval workflows — at scale on AWS.

• Designed and developed microservices using NestJS/TypeScript with DDD and Clean Architecture patterns.
• Built a React/TypeScript SPA supporting complex multi-step approval flows for agricultural tickets with role-based access control.
• Architected an event-driven integration service that ingests sales adjustment events from third-party ERPs via Apache Kafka (AWS MSK) and routes them through a modular handler system.
• Maintained 80%+ test coverage enforced via pre-commit hooks, with automated lint and formatting gates.
• Modeled and maintained MongoDB collections across multiple services using Mongoose schemas — covering tickets (workflow state + attachments), users/growers, bonds, sales data, bonification rules, audit/activity logs, and a notification topic hierarchy; each service owns its own collections following microservice data-isolation principles.
• Implemented a schema migration system (migration + migration-lock collections) to safely evolve document schemas across environments without downtime.

It’s independent, end-to-end product development, building web and mobile apps for early-stage clients from concept to production, with full ownership across tech and delivery.

• Led front-end development across Vue.js, React, and Angular with micro-frontend architecture.
• Designed scalable micro-frontend solutions and contributed to the design system establishment.
• Collaborated cross-functionally to define UI/UX patterns and drove design system component adoption.
• Streamlined UI development using Tailwind CSS within Agile iterative processes.

It’s a digital banking platform for a credit cooperative to enable independent team development and scalable feature delivery.

• Architected enterprise-grade front-end solutions across 5+ projects.
• Designed cloud-native architectures using Azure DevOps and AWS.
• Established architectural standards for multiple enterprise initiatives.
• Migrated 3 legacy applications to modern cloud-native architectures.

It’s an enterprise online banking web app that enables independent team delivery and provides accessible, full-service banking features.

• Developed front-end features with AngularJS/Angular.
• Built back-end logic with Node.js/Java Spring.
• Guided team on software engineering best practices and continuous evolution training.

It’s two platforms I worked on: one is a real-time manufacturing monitoring system for production operations, and the other is an agricultural management platform for tracking farm workflows and data.

• Led front-end teams across manufacturing and agricultural technology projects.
• Established development standards and coordinated with backend teams.
• Managed a team of 3 front-end developers.
• Delivered manufacturing platform ahead of schedule.
