“Isaac Flath is a gem! ... Under his guidance, a project we had been struggling with for a year was cleaned up and completed in 2 months! ... Words are not enough to express how much we cherish his guidance.”
How I Work
I dig deep to understand your problem, try different approaches to solve it, and iterate until we get it right. Problems get a lot easier when you actually understand them.
Understand
I use error analysis, feature definition, and custom eval tools to dig into your specific problem until it makes sense.
Key Point
Understanding the problem is half the solution
Experiment
I try different approaches and see what works best, getting feedback fast so we can move forward.
Key Point
Fast experiments beat long meetings
Iterate
We take what we learned, make it better, and keep refining until we get it right.
Key Point
Small improvements add up
Guide
I work with your team to transfer knowledge. You own the solution, not me.
Key Point
Build capability, not dependency
