Richard Injante, author and reviewer

The calculators on this site are not signed by a brand: they are signed by a person, and here are the details so anyone can check them.

Who I am

My name is Richard Enrique Injante Ore and I sign as Richard Injante. I am a lecturer and researcher at Universidad Nacional de San Martín, in Tarapoto (Peru), where I have worked since 2007. My fields are software engineering, web engineering, data science, computer science and machine learning.

Where to verify it

• ORCID: 0000-0002-2449-8937 — https://orcid.org/0000-0002-2449-8937
• Google Scholar: https://scholar.google.com/citations?user=uQ5vTT4AAAAJ&hl=es (with the institutional email unsm.edu.pe verified)
• Scopus Author ID: 57216730269

Those three identifiers are public and this site does not issue them: ORCID, Google and Elsevier do. If anything claimed here does not match them, believe them instead.

What I do at KalCum

I review the formulas before a calculator is published, check the results against cases with a known solution, and decide which criterion applies when more than one is accepted. The full procedure is written out on the methodology page, with the checks every tool goes through.

I do not write the texts with a language model, and I do not let a model compute anything: results come from deterministic operations written in versioned code. If you find an error, write to contacto@kalcum.com telling me which tool and which inputs: it gets fixed and the review date is updated.

Conflicts of interest

This site sells no financial products, no health products, nothing at all, and charges nobody to appear on it. The calculators are free and need no sign-up. Nothing published here is professional advice: they are calculations with the formula in plain sight so you can check them yourself.
