Share your story. What internal tool or app has your team or a previous team built that helped you the most.

Well I built a symbolic comoutating engine from scratch that would have taken 4 PhD's work all by myself, to solve specific type of equation in quantum physics. That goes way beyond my boss' expectation, he thought such program would be impossible to write but I just did it. What it is doing is kind of like solving matrix multiplication. Decompose large matrix into summation of smaller once to reduce O(n) figure for better scaling. My program can decompose tensors automatically and the result is compiled as executable code. It will be the foundation for a fore-coming paper.

Besides that, I encourage my team to ban using a Google collaborated OSS library. Instead I reinvent wheels and implemented mine with new algorithm, which is 20X performance still using Python as what they did, by that our in-house software's runtime reduced by 80%.
