Nebluna Inventory & Sales

Nebluna Inventory & Sales

Full-Stack

Inventory and sales system for a specialty coffee micro-roastery in Mexico City. Covers the full cycle: green coffee, roasting, bulk stock, packaging, sale, shipping and reporting. Next.js 16 and TypeScript on Supabase.

Objective

Move the operation off a spreadsheet and onto a system where the database enforces the business rules, and where the sales team works with the catalogue and their own commissions without access to financial data.

Objective

Give small coffee shops a demand forecast they can operate from a browser, with the model served behind a REST API rather than living in a notebook.

About Me

Profile picture

Fernando Rios

ML Engineer & Full-Stack Developer

About Me

ML Engineer with end-to-end experience: I train models, deploy them to production and automate the pipelines with MLOps. I came up through full-stack development, so to me a model does not end at a validation metric. It ends in an interface where someone uses it to decide something.

What I can cover

I can take a data problem, train a model, deploy it to GCP or AWS with CI/CD, and build the dashboard the end user works in. The full cycle, from problem to product.

Right now

I'm building Nebluna Café, my roasted coffee brand. Nebluna Analytics came out of it: the demand forecasting system listed in the projects, built to solve a real problem in the business. Open to ML Engineer roles and to freelance ML or data projects, end to end.
