Context
At Azify, I worked as a consultant on financial infrastructure for fintechs and smaller banks. The product covered capabilities such as Pix, transfers, cards, digital wallets, and other banking services.
How I worked
I contributed to architectural decisions and helped establish engineering practices for an environment where consistency, security, and stability had direct financial impact. I built a NestJS settlement engine with multi-exchange integrations, risk monitoring, and compliance controls.
I also worked on exchange and blockchain integrations for transactional flows and on a multi-tenant BaaS platform using OAuth 2.0, JWT, and encryption. Through query profiling, index review, and Redis optimization, I reduced latency in critical financial APIs by 30%.
What I took from it
This consulting work brought recurring parts of my trajectory, including payments, multi-tenancy, and transactional systems, into a setting with even greater responsibility for authorization and consistency.
