Helmut – Python, LLM, Java

A Research and Development project, developing an AI platform similar to ChatGPT web, with additional features like allowing users to build artificial intelligence agents and use user-specific files with the LLM engine.

• Achieved 1200 new users onboarded in the platform MVP in the first year of development.
• Dealt with prompt engineering, automated agents creation, and building software equipped with custom knowledge bases and memory.
• Integrated and developed solutions with leading LLMs on the market (Azure OpenAI and Amazon Bedrock), Retrieval-Augmented Generation (RAG), search engines, Python, and React.
• Deployed and managed scalable environments using Terraform, Docker, and AWS infrastructure.

A telemedicine scheduling and service platform. The integration of generative AI to assist in real-time patient diagnosis was a key aspect, enhancing the platform's capabilities and user experience.

• Achieved 6000 Patient/Doctor appointments since the inception of the MVP.
• Led the development of the platform and the web, which led to marketing campaign strategies.
• Integrated generative Artificial Intelligence to assist in real-time patient diagnosis.

Helmut completed several projects, including:

• Amway e-commerce product recommendation: Java (backend), React (frontend), Kafka with Spring batch (real-time processing), PostgreSQL (RDBMS), AWS, Docker, and Kubernetes for infrastructure.
• Oncoclínicas and Celer Biotechnology's telemedicine platform: video streaming, websockets for signaling servers, a WhatsApp chatbot, SMS, email, and push notifications (Twilio and GCP integrations).
• Algorithmic investment trading: quantum trading for automated investments in stock markets using Metatrader and Python with Selenium for web scraping.

• Developed backend systems using Java and Python.
• Built and maintained integrations with various external cloud tools, along with containerization and orchestration using Docker and Kubernetes.
• Led cross-functional teams, often mentoring less-experienced professionals.
• Took on multiple roles, including technical mentor, problem-solver for high-priority issues, and clear communicator to ensure client satisfaction and alignment with business goals.
• Spearheaded agile, high-pressure deliveries, such as the rapid launch of a telemedicine platform at the onset of the COVID-19 pandemic. This project played a key role in the success of the Oncoclínicas Group, which expanded during the crisis and attracted investment from Goldman Sachs, becoming one of Brazil’s leading healthcare companies.
• Led innovative and technically demanding projects, including a global product recommendation system tailored to individual user profiles for Amway’s e-commerce platform.

The home automation project involved controlling and monitoring equipment such as cameras, lamps, alarms, and security through user biometrics (Internet of Things).

• Created front-end and back-end architecture;
• Wrote unit, integration, and e2e tests;
• Deployed to Cloud Computing services;
• Set up NoSQL databases.
