Eduardo Bilato

Senior engineer on Traact's contract-lifecycle platform, working across the full stack on entity management, permissions, and AI integrations. Led a cost and quality revamp of the contract-AI pipeline (intelligence-service) and is transitioning into a Tech Lead / Principal Engineer role, technically driving the Blue Label vendor entity-binding project.

• [-99%]Migrated the contract-AI base model from GPT-4-0613 to GPT-5-mini, cutting input-token cost ~120x and output-token cost ~30x
• [-80%]Migrated the document-embedding model to text-embedding-3-small, cutting embedding cost for RAG/autofill ingestion
• [$5K→$10]Re-ingested ~6,000 existing platform documents into the new embedding pipeline for under $10, versus an estimated $5,000 with the naive approach
• Redesigned contract autofill to skip reprocessing already-filled documents, eliminating redundant intelligence-service calls
• Found and fixed cross-tenant data-isolation vulnerabilities (groups, contracts, invoices, boards, tasks leaking across workspaces), with automated test coverage
• Designed an internal multi-agent AI pipeline (PO -> Architect -> Developer -> Reviewer -> QA) to accelerate feature delivery from Linear tickets

Led creation of a new document platform (Documentor) from legacy code, an AWS EKS environment, an Import Agent, and Keycloak-based auth, while leading the Volkswagen national sales-proposal automation project.

• [-70%]Reduced Volkswagen proposal analysis time
• Set up AWS EKS cluster with EC2 worker nodes for the platform
• Built multi-tenant, multi-threaded RPA for document imports using Node.js worker-thread-pool
• Integrated Keycloak (OAuth2) for authentication and user sync across legacy tenants
• Led CI/CD via Docker, BitBucket Pipelines, and Argo CD

Owned architecture for the Manifestações platform (5 Node.js APIs, 2 frontends, RabbitMQ, ElasticSearch, Camunda BPMN) for Bradesco via the NewSpace BPO group, including a document classification bot and an email management bot.

• [-62%]Cut API response times with Redis caching
• [+65%]Increased user efficiency with an integrated email bot (send/receive/attachments)
• [-40min]Saved deployment time per release by integrating ArgoCD for image management
• Built Redis fallback for RabbitMQ instability on IBM Kubernetes, preventing message loss
• Used MongoDB cursors to prevent crashes processing large datasets

Built microfrontend architecture (Node.js, Redux, Kraken.js, TypeORM, React.js, RabbitMQ, MongoDB) for a Bradesco automation workflow via NewSpace, unblocking a project stalled for three months and setting up Azure Pipelines + ArgoCD CI/CD.

• Unblocked a project stalled for three months through cross-team collaboration
• Started a documentation culture (setup to deployment), improving onboarding speed for new developers
• [23%]Retained in the team through NewSpace restructuring — among the top developers kept

Self-funded transition into modern web development by building and selling a paperless system for an aesthetics clinic: a Node.js/TypeScript API, an Electron.js Windows client, and a React.js tablet client, all containerized with CI/CD.

• Designed and shipped a 3-part distributed system (API + Windows client + tablet client) solo
• Eliminated all paper-based registration and treatment forms for the clinic
• Self-taught Node.js, TypeScript, React.js, Electron.js, Docker and CI/CD while delivering the project

Twelve years maintaining and evolving a monolithic ERP (xHarbour/FiveWin, MySQL/DBF): banking integrations, NF-e electronic invoicing, device integrations, and internal tooling that sped up the whole team.

• [-25%]Built a responsive-screen framework, cutting development time for new screens
• [+30%]Built a dynamic report generator, speeding up report creation
• [-70%]Automated database schema updates across releases, cutting dev time and eliminating manual errors
• [-30%]Built DOCHTML, a dynamic documentation generator adopted by the COBOL team too, cutting support interruptions
• Led integrations with electronic scales (Fizzola, Toledo) and Zebra label printers via serial/IP
• Led migration project from xHarbour to .NET, building a socket-based API bridge (VSApi)
