May 24, 2024
The end tends to be much sexier than the beginning. Think about it, when we set ourselves a new challenge, we immediately think about the most gratifying aspect of it. These are some lessons from my story of how starting from the end when building my startup, Lagrange Systems, led us to failure.

Lagrange: AI-driven Scheduling for Restaurants

Apr, 2023

Lagrange started as a staffing schedule generator for restaurants. The problem to solve is simple, schedule the right amount of staff at all times. This means forecasting how many customers will the restaurant receive per unit of time (the demand), how many customers each team configuration can handle (the capacity) and to use this information to build actual schedules ahead of time that supply enough team members in all areas to deliver to all customers while minimizing the payroll (the plan), all while respecting staff preferences and business rules (the constraints)


About me

Hello! I'm Luis Da Silva, originally from Venezuela and now based in the UK. My background is a blend of Economics and Data Science, but my career has taken an exciting turn towards Software Engineering and Entrepreneurship.
I'm the founder of Lagrange Systems, where we're using AI to revolutionize how restaurants manage pricing and staffing. Before that, I honed my technical skills as a Tech Lead at EMIS Health.
I thrive on challenges and I'm always on the lookout for intriguing problems to solve. And when I'm not immersed in code, you'll likely find me exploring the countryside on a run 😉.
