Portrait of Roy Dabire

Roy Dabire

ML engineer focused on practical, production-ready systems.

I spend most days turning messy ML ideas into tools people can actually use, not just demo once and forget.

How I like to work

I usually sit in the middle of product, data, and engineering. The best projects for me start a little messy, get shaped with the team, and end up as something useful in day-to-day work.

A lot of my work has been in mining and heavy industry, but the same rules keep showing up everywhere: understand the workflow, build with constraints, ship fast, and keep listening to users.

Outside project delivery, I like writing practical ML notes and helping teams get better at modern AI without the hype spiral.

Journey

Dec 2025 - Present

Fortescue

Machine Learning Engineer

  • • Designing, experimenting, building, and deploying production-ready machine learning models in Python using Amazon SageMaker.
  • • Engineering and maintaining data pipelines for ingestion, preprocessing, and feature engineering with AWS services including S3 and Lambda.
  • • Working with domain experts and product owners to translate mining and processing needs into clear ML problem statements with measurable success criteria.
  • • Applying MLOps practices including CI/CD workflows, automated retraining, and monitoring for model performance drift.
  • • Running analysis and experimentation to validate hypotheses and improve recommendation and predictive models for operational efficiency.
  • • Supporting live models in mineral processing environments with engineers and analysts, troubleshooting issues and continuously improving performance.

Newmont

Data Scientist, Generative AI

  • • Built agentic RAG workflows that reduced investigation effort by ~80% in real operational settings.
  • • Delivered AI tooling for role design and workforce planning used at global scale.
  • • Led practical enablement sessions on production GenAI, MLOps, and responsible adoption.

Data Scientist, Digital

  • • Developed predictive maintenance models that surfaced multi-million-dollar improvement opportunities.
  • • Translated messy operations data into decision-ready dashboards and interventions.
  • • Partnered with engineers and superintendents to ensure models actually changed behavior on site.

Early Career Roles & Internships

  • • Worked across geophysics, process analytics, and forecasting projects.
  • • Learned how much domain context matters when building reliable ML systems.
  • • Built a foundation in stakeholder communication, automation, and delivery discipline.

Operating principles

  • Models are only useful when users trust and use them.
  • Fast iteration beats perfect planning at the start of a project.
  • Good MLOps is a product decision, not only an engineering concern.
  • Responsible AI means clear boundaries, not just policy docs.
