Ph.D. candidate in condensed matter physics at UFC · customizing open-source LLMs at Kunumi Lab UFC
- 🔬 Ph.D. candidate in Condensed Matter Physics at the Universidade Federal do Ceará (UFC), where I also earned my bachelor's and master's degrees in Physics.
- 🌊 I simulate wave packet dynamics in graphene, in C, C++ and Python.
- 🤖 Since September 2025 I've been at the Fundação Cearense de Pesquisa e Cultura (FCPC), on the Kunumi Lab UFC project, customizing open-source large language models for process automation.
- ⚡ Finishing a technical degree in Electrotechnics at IFCE: microcontrollers, embedded firmware, instrumentation, signal conditioning and industrial control.
- 🌎 Based in Brazil · Portuguese and English
LLMatter2D A retrieval-augmented LLM for the analysis and discovery of two-dimensional materials: DFT, ARPES, tight-binding models and Archimedean lattices. |

AI and LLMs
| Project | What it does |
|---|---|
| wabot_python | FastAPI service that connects the WhatsApp Cloud API to OpenAI, Anthropic and Google Gemini, with runtime provider switching, automatic fallback, conversation memory, voice-note transcription and image/PDF understanding. |
| case-vicio-ia-classificacao | Decides, for each question, whether to publish it under a topic of a taxonomy, send it to a teacher for review, or mark it as off-taxonomy, with no language model in the decision. Plain Python, no dependencies. |
Live streaming and community tools
| Project | What it does |
|---|---|
| StreamDeck-Obs | A Stream Deck for OBS that runs in an old iPad's browser. Dependency-free Python plus an ES5 page. |
| holyrics-obs-label | Local server that publishes only the lyric currently on air in Holyrics, styled on a transparent background, ready to use as an OBS browser source. |
| python-ShareScreen | Shares the whole screen or a single Windows window, with audio, to any browser on the local network. One Python script. |
| Sorteio-RifaDigital | Drawing page for a charity raffle: load the rifa.digital report and it picks a winner at random, with fireworks and confetti. |
| IBVB-Campanha | Mobile-first Pix donation campaign site built on the Mercado Pago API and MySQL, updating the total as payments are confirmed. |
