Senior Product Engineer
AI-native product engineer with 11 years of experience shipping end-to-end solutions.
Who is Andre Treib?
Senior full-stack engineer with 11 years of experience shipping products end-to-end across Next.js, React, and Node. The last two years have been a step-change: I leverage AI coding assistants and purpose-built internal tooling to compress 4-week scopes into 3 days, then protect every shipped feature with rigorous unit, integration and E2E coverage. I build and operate RAG pipelines, agentic workflows over event-driven architecture, and a custom MCP server wired into our own tool-using AI agent.
Ships AI features end-to-end
RAG pipelines, agentic workflows over EDA, and a custom MCP server in production — from data ingestion and chunking through reasoning-based orchestration.
Builds for product impact
First engineer hired at a US SaaS, helped shape the roadmap and engineering culture, and have served as Product Owner before. Comfortable moving between IC depth and product-facing decisions.
Tested + observable by default
TDD across the full pyramid — unit, integration, E2E. 80% coverage on 12 production microservices, structured logging and telemetry, regression escape rate cut to near zero.

What people say about Andre Treib?
Check out some testimonials from people I have worked with.
"Andre brings a positive can-do attitude to his work, which is refreshing and motivating to be around. In terms of technical capabilities, he is very equipped to handle the work and is a continued advocate to improving the code base and the patterns used within it. He understands that it is appropriate to invest in best practices, but also at times it is best to drive toward near term goals and backfill missing pieces. Andre also appears to be a natural people organizer, getting everyone aligned toward success."
"Andre is one of the most talented and qualified professionals I have worked with so far. He does his work extremely well, with dedication and pro activity, and always with a great mood. We briefly worked together at Eldorado Research Institute and he helped me on my first steps there. Someone with high potential to achieve top ranks in any company due his commitment, respect, openness, focus and courage. It's impossible to not recommend his work. He is totally above average."
"Andre did a great job at Eldorado Research Institute where I had the chance to work with him. He's an excellent software developer and delivered all requests with a lot of quality and timely.
