Phinx Lab is a Buenos Aires-based software services firm building bespoke products in fintech, gaming, and mobile. The stack reveals a modern, containerized operation: Node.js + React frontend, PostgreSQL + Redis for data and caching, Docker + Kubernetes for orchestration, and a full testing pipeline (JMeter, k6, Newman) suggesting they're wrestling with high-concurrency and performance challenges. Current projects span API testing strategy and backend-for-frontend architecture, aligned with pain points around scaling traffic and stability in complex business flows.
