Professional Profile & Pedagogical Leadership
Mateo Byler
Known in the classroom and across his publications as Mr. Byler. Published educational author, applied linguistics specialist (Spanish-English contrastive grammar), and assessment evaluator.
The Science Behind Simplicity
Raised and educated between the United States (Indiana) and Spain, Mateo Byler possesses native bilingual competence and dual cultural fluency in General American English and Peninsular Spanish. Across more than a decade of intensive classroom instruction in Burgos (Big Ben School), he documented a consistent cognitive pattern across hundreds of adult and teenage learners: communication breakdowns in English do not stem from poor memory, but from involuntary subconscious interference from the native language (L1 $\rightarrow$ L2 negative transfer).
Complicating grammar with dense academic jargon is effortless; the true challenge of applied linguistics lies in translating complex theoretical frameworks into immediate, operational intuition. His editorial imprint at SpeakEnglish.VIP targets and eliminates fossilized linguistic habits through original cognitive frameworks: spatial vector deconstruction of phrasal verbs, neutralization of syntactic calques, and calibrated zero-deduction writing matrices for high-stakes examinations.
Technical, Institutional & Pedagogical Track Record
Official Assessment in Public Sector Competitions
Has served as an appointed independent language examiner and technical advisor for local public administration recruitment competitions (Burgos City Council / Ayuntamiento de Burgos), calibrating assessment rubrics, establishing scoring deduction thresholds, and directly evaluating candidates’ oral and written communicative competence.

Deep expertise in psychometric distractor deconstruction and zero-penalty syntactic essay modeling.
Digital Infrastructure & EdTech
Systems administration background managing virtual learning environments (Moodle LMS) for research institutes, deploying multi-server web platforms, and optimizing semantic web performance under rigorous privacy standards.
Published Works & Applied Methodologies
Each publication in the catalog represents applied linguistic research designed to resolve specific cognitive bottlenecks experienced by Spanish speakers learning English:
Contrastive Grammar & L1 Remediation
El Libro de Inglés que te hubiera ahorrado años de estudio
380-page reference work (ISBN: 978-84-09-81561-6). Systematically dismantles negative transfer from Spanish, syntactic calques in corporate correspondence, and fossilized false friends across CEFR levels B1 to C2.
Cognitive Semantics & Vector Logic
Learn Phrasal Verbs Without Memorizing Them
271-page visual framework substituting rote alphabetical memorization with the spatial and directional physics of 12 satellite particles, enabling predictive retrieval of complex multi-word verbs.
Rubric Calibration & Test Architecture
PAU Castilla y León: Inglés
Standardized exam guide with 10 full mock exams calibrated against official regional marking rubrics, distractor analysis, and modular writing templates engineered for zero-penalty performance.
Healthcare ESP & Clinical Precision
Workplace English for Healthcare Workers
Situational communication manual for healthcare providers in anglophone settings: patient intake, handoffs, vital signs terminology, and culturally empathetic clinical interaction.
Diagnostic Writing Assessment & Linguistic Consulting
