Performed word-level transcript correction and millisecond-precision audio-text alignment for speech-recognition training, held to strict accuracy and consistency thresholds.

Built and applied multi-step evaluation rubrics for civil, structural and geotechnical engineering reasoning, enforcing domain accuracy and instruction adherence. Identified critical failure modes and structural hallucinations, and ran pairwise model comparisons and output ranking against verified ground-truth references.

Evaluated and ranked live speech-to-speech conversations with AI models across defined scenarios, assessing naturalness, engagement, and utility. Delivered comparative preference rankings that feed RLHF pipelines.

Performed text intent analysis, SFT annotation, and RM ranking & scoring for LLM training datasets. Conducted speech transcription, audio annotation, and localisation collection under LGPD-compliant data-handling protocols.

Conducted live multi-turn voice benchmarking in blind pairwise ELO arenas, assessing conversational flow, utility, and naturalness. Classified failures by severity and authored structured, timestamped justifications to guide reinforcement learning and post-training refinement.

Built an automated QA system scaling technical validation to 1,400+ infrastructure projects, detecting logical inconsistencies and regulatory violations. Developed Python and Excel-VBA pipelines for classification and validation, and audited third-party documentation against regulatory criteria.

Coordinated and trained a team of 10+ engineering interns, acting as the final quality gate on every deliverable. Owned the project pipeline including scope, deliverables, deadlines, and approval cycles with external regulatory authorities.

Performed reinforced-concrete structural design and detailing, multidisciplinary BIM coordination and clash detection, geotechnical slope stability and retaining structure design, and urban infrastructure design. Authored SOPs translating complex software workflows into reproducible team documentation.

Conducted geotechnical laboratory testing including direct shear, triaxial, permeability, CBR and soil characterisation, and field sampling and instrumentation. Reviewed and contributed to academic publications in geotechnics, roads and pavement engineering.

Bachelor of Science in Civil Engineering, with a thesis on deterministic and probabilistic analysis of a gabion retaining wall.

Postgraduate specialization in Geotechnics.

Technical degree in Information Technology.
