Pablo Ferrari

Backend Developer

About

Backend developer with 10+ years building systems across industries — real estate, fintech, gaming, EdTech, telecom. Different stacks, different problem domains, different teams. The constant is that I've always owned things end-to-end: design, build, deploy, maintain.

In my current role at Unicity I went deep on global payment systems — integrating 10+ providers across NA, EU, and APAC, implementing 3DS v2, and recovering over $850K in failed transactions. In 2021 I joined Crowdability (NYC) as their first internationally located hire — no playbook existed for it.

Marathon runner. Long-term thinking comes with the territory.
