Heitor N.

Recently, I led the end-to-end development of a high-performance R&D system in Australia, featuring:

Cloud & DevOps:

AWS infrastructure orchestrated with Docker, Traefik (reverse proxy), and Keycloak (security).

Full-Stack Web:

Mobile-friendly React.js/TypeScript frontend integrated with Node.js (Express/Sequelize) and FastAPI microservices.

IoT & Data:

Custom FTP server (FastAPI) for real-time camera dumps, automated AWS S3 uploads, PDF scraping, and database indexing.

AI & Vision:

Local LLM deployment (OpenUI), EDA (Pandas, NumPy, OpenCV), and an advanced photogrammetry pipeline for automatic volume estimation.

Machine Learning:

Multilinear regression models (XGBoost, Random Forest) using Keras/TensorFlow.

Developed and Optimized Web Applications for Data-Driven Solutions

Contributed to the development of two React and Flask-based applications, focusing on authentication, real-time data visualization, and performance optimization to enhance user experience and system efficiency.

Key Accomplishments:

🔐 Authentication & Authorization System: Designed and implemented a secure user management system, including role-based access control and logging mechanisms.

🚀 Performance Optimization: Improved file upload efficiency and overall system responsiveness, enhancing scalability and user experience.

📦 Dockerization: Containerized the application using Docker, streamlining deployment and ensuring consistency across environments.

📝 Form Validation & UX Enhancement: Implemented robust form validation mechanisms to enhance data integrity and user interactions.

📊 Real-Time Data Visualization: Developed a dynamic interface integrating REST APIs and WebSockets for real-time data updates, leveraging Plotly for complex visual analytics.

🛠 Agile Development & Collaboration: Worked within an Agile environment, ensuring efficient project management, iterative improvements, and seamless collaboration.

Directed the development of "Engage Mode," a sophisticated SaaS platform that enhances business development across diverse industries. This platform leverages advanced AI, including tuned Large Language Models (LLM) and Mistral, to refine client engagement processes, automating the creation of personalized business outreach communications.

Key Accomplishments:

🤖 Advanced AI Integration: Implemented and fine-tuned Large Language Models to analyze and interpret complex business data, enabling the platform to identify potential clients and generate targeted communication strategies.

💌 Personalized Email Automation: Utilized AI-driven insights to automate the creation of highly personalized emails for business development, thereby increasing efficiency and engagement rates.

🖥️ Modern Full-Stack Development: Led the development using SvelteKit and Nest.js to create a highly responsive and maintainable web application, enhancing the user experience and system performance.

🔒 Enhanced Security and Compliance: Ensured top-tier data security and compliance with international standards, implementing robust CI/CD pipelines for continuous integration and deployment with Gitlab.

🎨 UI/UX Design with Tailwind CSS: Crafted an appealing and user-friendly interface using Tailwind CSS, facilitating seamless user interactions and accessibility.

⚙️ System Scalability and Optimization: Optimized backend services using Nest.js to handle large volumes of data efficiently, ensuring quick response times and scalability.

🤝 Team Leadership and Collaboration: Fostered a collaborative development environment, coordinating effectively with AI specialists, data scientists, and UI/UX designers to align the platform’s development with strategic business goals.

📄 Documentation and Architecture Best Practices: Maintained thorough documentation and upheld best practices in system architecture, enabling straightforward future enhancements and feature integrations.
