Meet the engineering team

Ignacio https://www.linkedin.com/in/ignaciobrasca shaped the baseline of our integration framework from scratch in a single weekend, then spent most weekends coordinating the team while shipping what was never on the roadmap: webhooks, a search engine for millions of transactions, and Puma itself. Pure initiative, compounding.

Marcin https://www.linkedin.com/in/mkuzdowicz took a non-existent tax structure and built it end to end, setting the north star for how the team keeps improving it on top of it; modular and robust, always setting the bar for the rest.
