ARTHUR CLARO

- Developed a cutting-edge AI tax platform end-to-end, contributing to the frontend (TypeScript/React), backend (Python/Node.js with REST APIs), and implementing AI agents for automation and optimization of complex fiscal processes, significantly reducing manual analysis time by an estimated 30%. - Architected and integrated AI agents (LangChain) to process and interpret tax legislation, enhancing compliance efficiency and accuracy. - Developed scalable and secure RESTful APIs, focusing on seamless integration between frontend, backend, and language models, ensuring data consistency and traceability. - Built robust ETL pipelines from heterogeneous external sources (APIs and crawlers/scrapers with Python/Playwright and FastAPI), performing transformations with Polars and pandas, storing data in parquet/gzip on AWS S3, and implementing schema validation, retry mechanisms, and monitoring for data reliability. - Orchestrated data pipelines with Apache Airflow (DAGs, retry, backfill); implemented asynchronous messaging via Kafka and RabbitMQ for decoupling producers and consumers; utilized Redis for session caching and rate limiting; provisioned infrastructure (Kubernetes on GCP, queues, S3) using Terraform. - Ensured platform observability with Grafana, Datadog, and ELK Stack, creating systemic metric dashboards, SLA alerts, and production log analysis, which reduced Mean Time To Resolution (MTTR) for critical incidents by approximately 25%. - Collaborated within an Agile (Scrum) environment, participating in continuous delivery cycles, code reviews, and deployments via CI/CD pipelines.

- Executed full stack development for the falecomigo.ai platform, designed to streamline entrepreneurial operations through artificial intelligence and advanced technology. - Implemented frontend functionalities using React.js/TypeScript and backend services with Node.js/NestJS, integrating with AI APIs and PostgreSQL and MongoDB databases. - Utilized RabbitMQ for asynchronous queues to process conversation events and Redis for session caching, ensuring high reliability and scalability of platform integrations. - Managed data flows and business logic, implementing OAuth2/JWT authentication to secure interactions and maintain data integrity across modules.

- Developed new features and resolved bugs in systems integrated with government platforms (gov.br), focusing on quality, accessibility, and regulatory compliance within a corporate environment utilizing an Oracle database and PL/SQL queries (stored procedures, views, query optimization). - Implemented web application enhancements using TypeScript and Angular, ensuring high performance and an optimal user experience for critical e-government systems; integrated with REST APIs and external services via SQL Server for data reconciliation and reporting. - Actively collaborated with the system analyst team, participating in code reviews, merge requests, and adhering to best practices for repository management and version control with Git.
