I’m a data scientist and investment consultant trying to automate my own quantitative research. Today I build multi-LLM systems in R that talk to more than 20 providers, benchmark models, and orchestrate them as “committees” to write research, marketing copy, and client reports for my firm, Senhor Mercado. I love turning scrappy prototypes into tools other people can use, from finance dashboards and backtesting frameworks to small robotics experiments with ESP32 and Orange Pi. I’m excited about open, hackable AI ecosystems and sharing what I learn with other tinkerers.
