How Much SQL, Python, Power BI You ACTUALLY Need in 2026 (AI changed the answer)

In this video I break down exactly how much SQL, Python, Excel, and Power BI you actually need to get hired as a data analyst in 2026, now that AI has changed the bar. I cover why beginner-level skills aren't enough anymore, how to test whether you can actually catch AI's mistakes, and tool-by-tool guidance on where "enough" is for each one. I also share what a 2026 portfolio needs that a 2023 one didn't, plus my playbook for landing the job.

I Built a Smart Scale That Calculates Calories in Real Time

She built a smart AI food scale that can recognize food, measure its weight, and estimate calories and nutrition in real time.

The system combines computer vision with a real load cell. A custom-trained YOLO model runs locally on an NVIDIA Jetson Orin Nano to identify the food, while a Seeed Studio XIAO RP2350 and HX711 measure its weight.

The touchscreen then combines the detected food with the measured portion weight to estimate calories, protein, carbs, and fat without manually logging everything into a phone app.

For this prototype, I trained the model to recognize strawberries, croissants, raspberry macarons, and fruit tarts. I also designed and 3D printed the enclosure from scratch and added a multi-food plate mode that keeps track of foods as they are added.
