Sobre mim
I build systems that pull decisions out of images and data. MSc in Engineering, highest distinction. Photo restoration: old, torn and faded photographs, using restoration models plus manual correction so the face still looks like the person you remember. Computer vision: object detection and tracking from video (YOLOv8, mAP 0.716). Quantitative development: four trading indicators published on ClickAlgo for cTrader, in C#/.NET. Data: Python, SQL, ETL on BigQuery, Power BI dashboards. Tell me what you have and what you need. I'll say honestly if I'm the right fit.... Saiba mais
