Meet the Engineering Team
Ignacio shaped the baseline of our integration framework from scratch in a single weekend, then spent most weekends - while coordinating the team - shipping what was never on the roadmap: webhooks, a search engine for millions of transactions, and Puma itself. Pure initiative, compounding.
Marcin 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.
Puhiza grew her team from one to full capacity, while owning our integration framework end to end; scaling it to support migrations, integrations, and bank connections. The queen of I/O on our platform.
Danylo took ownership of our bank connection engine end to end and rebuilt it from scratch over a weekend.
How You Operate
Pragmatic: you like to move forward and make decisions based in reality (not theory). We don't debate if Cassandra has the most theoretical scalability - we use Postgres until it breaks
Hard working: 'You can work long, hard, or smart, but [here] you can't choose two out of three' - Jeff Bezos.
Curious: you love to learn, are highly curious about new frameworks and solutions to engineering problems
Fast-moving: you deploy daily, iterate quickly, and never wait for permission
