Senior Data Professional·A Coruña, Spain

David Centeno Pedrido: I turn raw data into decisions.

I'm David Centeno, a senior data professional with 10+ years across analytics, data science and analytics engineering. I work end-to-end: from raw data and the models on top of it, to the room where the decision gets made.

01stg_about

Deep foundations, practical output.

Portrait of David Centeno Pedridohover for colour
fig. 01A Coruña, Spain

I've built production ML systems, designed analytics platforms from scratch, and partnered closely with product, commercial and leadership teams to turn data into decisions people actually trust.

My foundations are mathematical (a BSc in Mathematics and two years teaching statistics at master's level), but my work is practical: the dbt model, the metric definition everyone agrees on, the dashboard that replaces a weekly spreadsheet, the model that ships inside the product.

Lately I've been focused on modern analytics stacks and applied AI, building and shipping my own LLM-powered products. I do my best work as a senior IC with real ownership, and I step up to lead when the team needs it.

Things I've built and shipped.

Two live products where LLMs do real work: one as a careful editor that can't invent facts, one as a semantic judge. Designed, built, deployed and measured end to end.

ResuMatch

Tailor a CV to any job without inventing a single fact.

Upload a CV, paste a job advert, get back a tailored Word document plus an honest strengths / weaknesses / gaps analysis. The hard rule: the model may select, reorder and rephrase, but never invent employers, titles, dates, numbers or skills.

UnDictionary game round: a word, its difficulty, and hidden meanings for the player to describe in their own words

02live · personal project

UnDictionary

A word game where an LLM judges meaning, not wording.

Guess every definition of a word. Your answer doesn't need to match the dictionary; it needs to mean the same thing. An LLM acts as a semantic judge rather than a text generator, deciding whether each guess matches a valid definition.

LLM-as-judge: prompts and evaluation logic that compare meaning against multiple valid definitions
Casual, Challenge (race the clock) and Daily Challenge modes, with hints and scoring
Event tracking to study drop-off, difficulty and which definitions are hardest to guess
