Stella Bullo · Applied Linguist & Language-Tech Developer (EN/ES)
Applied linguistics translated into structured, interpretable language-tech systems for annotation, evaluation, and semantic modelling (EN/ES).
What I do
I work on the language layer of AI systems and datasets. My focus is on annotation and evaluation design, semantic modelling, and building interpretable language systems for multilingual speech and text (EN/ES).
Available for AI training, annotation QA, and language system design (EN/ES). If you need someone to strengthen the language layer of your dataset, evaluation pipeline, or product, let’s talk .
Annotation & Evaluation (EN/ES)
I design annotation schemas, guidelines, prompts, and QA frameworks for multilingual speech and text datasets, ensuring clarity, consistency, and high-quality training data.
Semantic Modelling & Language Systems
I model how people express meaning, emotion, and evaluation, and translate those linguistic frameworks into structured, interpretable systems implemented in annotation pipelines and digital products.
Applied Language Systems
Selected work demonstrating how semantic modelling, annotation design, and evaluation frameworks are implemented in structured, interpretable language systems.
Featured system
A linguistically grounded, rule-based application that translates metaphorical and literal pain descriptions into structured summaries. Built with Flask, YAML taxonomies, and a transparent interpretive framework.
MVP · Live prototype
Modelling framework
Design and implementation of taxonomy-driven language systems that formalise experiential and evaluative language. Includes technical articles on modelling methodology and system architecture.
Professional practice
Analytical articles on multilingual annotation design, speech verification, schema development, and evaluation QA for AI training datasets. Includes reflections on linguistic quality assurance and structured assessment practice.

I’m a trained linguist with a PhD in Applied Linguistics and 15 years of academic research experience in the UK. My work focused on corpus analysis, categorisation, and systematic interpretation, building analytical frameworks that made patterns of meaning visible and testable.
After relocating to Argentina, I moved into applied language engineering. Today I design annotation frameworks, evaluation logic, and rule-based systems that support reliable AI training data and interpretable digital products (EN/ES).
The intellectual core of my work has remained consistent: I build structured systems that make meaning operational.
Research foundation
Research on metaphor, evaluation, and lived experience in language. The theoretical basis for my modelling frameworks and applied systems.
