Software Engineering student building Python LLM agents for game localization, tripling translation throughput.

Brazil
Message

I designed and built a Python harness of LLM agents that translates and reviews games for real clients. It tripled my throughput from 300 to about 900 words per hour, with human review kept on every delivery.

The harness uses translator and reviewer agents for accuracy, fluency, and game mechanics. I added Python hooks to control where agents can write, an anonymization layer to keep client data out of git, and a queue for human approval of unattended decisions.

As an AI Evaluator on short-term freelance projects via micro1 and Mercor, I evaluated Portuguese LLM responses against rubrics, rated images, and annotated robotics data for model training.

At Keywords Studios, on the Bungie and Supercell teams, I translated and ran linguistic quality assurance on Destiny 2 and Supercell games. As a freelance Game Translator and Linguist, I’ve translated over 1 million words from English into Brazilian Portuguese, and I’m studying Software Engineering at Instituto Infnet.
