A business analytics dashboard that turns any sales CSV into KPIs, charts and forecasts — pointed at a new dataset by editing a column mapping rather than the code.

A research platform comparing Q-Learning and Deep Q-Learning for resource-constrained edge AI, with simulation, real-time training, telemetry, and future federated-learning experiments.

A compact Linux pipeline coordinating processes, POSIX IPC, worker threads, and aggregation to transform tick CSV records into per-symbol summaries.
