Summary
👤
Senior🎓
Top SchoolMárcio De Campos is a Senior Software Engineer with seven years of experience building scalable full-stack systems and pioneering AI-native, agentic development workflows. He blends deep JavaScript and Python expertise—Node.js, React/Next.js, Nest/FastAPI—with production-ready backend architectures (Kafka, Redis, Postgres, Mongo) and cloud-native DevOps (Docker, Kubernetes, GitHub Actions). At startups and large tech labs he has driven migrations from monoliths to microservices, cut frontend build times by 85%, and sped analytics queries from 500ms to 40ms through creative schema and indexing strategies. He consistently leverages agent tooling (Cursor, Claude Code, MCPs, sub-agents) to scale delivery without headcount increases and to automate developer workflows across GitHub, Jira and Notion. Recognized for operational rigor, he implemented OpenTelemetry observability and RBAC at the GraphQL layer to improve monitoring and security posture. Based in Portugal with a Computer Science degree and ongoing master's work, he pairs hands-on engineering with a knack for pragmatic automation that multiplies team velocity.
