Work Experience

AI Engineer – Workflow Automation at ACP Cubido Digital Solutions

February 1, 2025 - March 1, 2026

Achieved higher knowledge-work automation, measured by ~50% lower user handling time, by implementing an LLM agent workflow with LangChain and RAG (retrieval + re-ranking) to automate Q&A and document-based tasks. Achieved improved solution quality, measured by fewer regressions across prompt changes, by implementing automated evaluation, regression tests, and structured observability for AI workflows. Achieved faster delivery of automation features, measured by shorter iteration cycles, by implementing modular Python services, API integrations, and clean interfaces for tool-use (function calling). Achieved reliable data foundations, measured by 100GB+ daily records processed, by implementing production pipelines with data contracts, validation, and monitoring. Achieved safer deployments, measured by fewer production issues, by implementing CI/CD with unit tests and code review standards.

Data Engineer at Bosch
