Maycon Ferreira / Rio de Janeiro, Brazil
I turn operational needs into automations, integrations and internal systems that people can use in their daily routines.
I work from process discovery and business rules through architecture, development, deployment, training, monitoring and support. My core is self-hosted n8n, Python, FastAPI, REST APIs, SQL/PostgreSQL and Docker, with applied AI, RAG/grounding and human review when they add value.

RESULTS IN USE
HOW I WORK
I understand the need, users, environment and expected outcome.
I map the current flow, exceptions, sensitive data, dependencies and failure points.
I define the source of truth, permissions, approvals, integrations and recovery.
I develop the system, automation, interface, persistence and contracts.
I install, configure, document and train the people who will use it.
I monitor logs, fix failures and improve the solution based on real use.

PROFESSIONAL EXPERIENCE
Junior Process Automation Technician official title
I own the end-to-end lifecycle of internal solutions: requirements, AS-IS/TO-BE mapping, architecture, development, deployment, training, monitoring and support. I have trained and guided 30+ people across office, factory and remote settings.
Data Engineering Scholarship Program
I completed ten practical sprints with Python, SQL, Docker and AWS, including CSV/TMDB API ingestion, S3, Lambda/boto3, Glue/PySpark, Parquet, Raw/Trusted/Refined layers, Athena and QuickSight.
