Michael E. Marin, ML Engineer

AI / ML Engineer

ML Engineer building production AI systems with measurable impact

Collaborated with NASA on applied ML research. Specializing in agentic AI pipelines, hybrid retrieval systems, and full-stack products that ship.

Flagship Projects

NASA PACE — Waving

Scientists needed an interactive way to explore real-time oceanographic satellite data.

Led 5-person team to ship a live visualization platform, now exhibited at Kennedy Space Center.

Experience & Projects

Product Analyst Intern, AI/ ML team
May 2025
Mr. Cooper Group
  • Selected for a competitive 10-week internship with the Product Management AI/ML team.
  • Contributing to the development and support of internal Agentic AI products to help automate customer service.
  • Responsibilities include story writing, user testing, model evaluation, and cross-functional collaboration with design, engineering, and business units.
  • Exposure to tools such as Azure DevOps, MySQL, Microsoft Copilot, Google Cloud Services(GCS), and LucidChart in support of digital transformation and intelligent automation efforts.
Waving: From Space to Ocean (Senior Project)
Jan 2024 – May 2025
Collaborated with NASA Goddard Program, University of Maryland, and UNT
  • Lead a team of 5 to develop a interactive data visualizations in React and TypeScript, enabling real-time analytics for NASA's PACE Satellite.
  • Built full-stack applications integrating cloud data pipelines for large-scale scientific computations.
  • Designed a Setup Wizard using ImGui and OpenCV, optimizing user configuration workflows.
  • Implemented scalable APIs and GraphQL endpoints for cross-platform data integration.
  • Currently being showcases at Kennedy Museum in Washington D.C.; Set to travel to different museums across the country.
RAGOps: Production-Grade RAG Platform
2024 – 2025
Personal Project
  • Built a production-grade RAG platform with hybrid retrieval (vector + BM25), cross-encoder reranking, and citation-based answer generation.
  • Designed end-to-end LLM pipeline: document ingestion, semantic chunking, embedding, hybrid retrieval, and generation using FastAPI and PostgreSQL (pgvector).
  • Implemented observability layer tracking retrieval latency, token usage, cost, and per-query diagnostics via an admin dashboard.
  • Developed evaluation framework with 150+ benchmark queries measuring Recall@k, MRR, and answer correctness.
  • Hybrid retrieval improved Recall@10 significantly over dense-only baseline; reranking reduced irrelevant context and improved answer precision.
