AI Product Engineer · Robert Grzonka
Meals, movement, a home, a movie marathon.
My projects tend to start with something in my own life.
01 / FEATUREDPublic demo
Taking better care of myself, day by day.
Meals, workouts and calorie goals in one place. Describe a meal or add a photo, review the nutrition estimate, and ask Evo about your day.
I started evoflow when I decided to take better care of my health. I wanted to see what I ate, how I trained and how my weight changed over time.
Recipes worth making again.
Recipes we’ve cooked and enjoyed, alongside ones we still want to try. Serving sizes, nutrition estimates and a cooking mode keep the recipe useful at the stove.
Browse the recipesFrom household stock to shopping
What’s at home, and what to buy.
Shared household supplies and a shopping list. Photos become product proposals, and stock history informs shopping suggestions. AI proposals wait for approval.

The handoff between recipe and meal.
Sous connects Jedzomko, Domio and evoflow. It plans shopping, tracks cooked batches and logs eaten portions, with proposals and corrections reviewed in one inbox.
Proposals from chat wait in the inbox for approval.
A financial plan I can keep revising.
Monthly cash flow, obligations and reserves, with saved scenarios to compare before changing the plan. I use it to work through the numbers as they change.
The core calculations are deterministic.
The person behind the projects
I’m an AI Product Engineer with roots in React and TypeScript. I build the whole product around the AI — including the tools it can use and the decisions people stay in control of.
theGuys is my one-person business and the home for my own products. Most began with something I needed in everyday life, from estimating a meal to working out what to buy.
