Freelancer Overview

I help teams ship reliable software and solve hard STEM problems. Software Engineering (Python): design and build APIs and micro-services (FastAPI), data/ETL pipelines, automations and CLI tools; solid tests (pytest), type-hints/pydantic, CI, and Docker for reproducibility; clean docs and small, reviewable commits. Math & Physics: modeling and simulation, algorithm design, sanity checks (units, bounds, error estimates), and clear write-ups; creation of problem sets, gold-standard solutions, and rubrics for training/evaluation; ability to translate complex ideas into concise, actionable specs. What you get: production-minded code, measurable outcomes, and transparent communication. I’m bilingual (PT-BR/EN), comfortable with async work and tight SLAs, and I provide short progress notes with every milestone. If you need a Python engineer who can also reason rigorously about math/physics, I’m a strong fit.

Project overview End-to-end data annotation and evaluation pipeline to train and test language models. In Python, I prepare datasets, build lightweight verification utilities, organize the labeling flow for text and audio, and consolidate quality metrics. The focus is clarity, consistency, and reproducibility: every decision is documented and auditable. Scope (what is included) Data curation: collection and cleaning, deduplication, encoding normalization, and formatting in comma-separated values or JavaScript Object Notation. Guideline design: label taxonomies, positive and negative examples, edge cases, and escalation policy. Labeling (text and, when applicable, audio): classification, entity extraction, evaluation of language-model outputs, side-by-side comparison, and prompt creation or translation. Quality assurance and metrics: sampling, automated checks, inter-annotator consistency, error traces, and regression tracking. Reporting and delivery: coverage spreadsheets, simpl
