Hi, I'm Augusto. I'm a 7th-semester Software Engineering student based in Brazil. I combine a developer's analytical mindset with native Portuguese fluency to handle Technical QA, AI Evaluation, and Localization projects. I bridge the gap between language and logic. If you need someone who understands the critical difference between text meant for translation and a JSON key that will break your application if touched, you are in the right place. "Augusto provided critical feedback enabling the team to improve much faster... I fully recommend hiring him." — Philip R., Indie Game Developer Here is what I bring to your team: 1. AI Data Evaluation & RLHF (PT-BR) I stress-test conversational models (LLMs and Voice Bots) to find edge cases. Instead of just logging "it sounds weird," I provide clear, reproducible error traces for prompt adherence, logic flaws, and unnatural phrasing in Portuguese so your engineers can actually fix the model. 2. Technical Translation & Localization I localize software and API documentation while strictly respecting code syntax, variables (like {{userName}}), and tags. I also deliver perfectly synced .SRT files for devlogs and technical tutorials using industry-standard terminology. 3. Game QA & Playtesting Bringing over 20,000 hours of gaming experience, I provide high-level feedback on game mechanics and balancing. More importantly, I deliver dev-ready bug reports focusing on UI/UX clarity, input lag, and hitboxes with clear reproduction steps. My Background: Education: 7th-Semester Software Engineering Student. Languages: Native Brazilian Portuguese | Fluent English (C1). Tools: Git, VS Code, Subtitle Edit, Jira, Bug Tracking Systems. Send me a message with a quick overview of your project, and let's get to work.
