What I'm looking for

I'm deepening my expertise in software architecture, with the goal of progressing toward a Software Architect role.

At Reflections Info Systems, I support a US-based banking institution with microservice migrations and optimize database queries to improve API responses.

At Qubika, I worked across backend and embedded systems projects, including customized OpenWRT firmware for lighting control devices and a modular Rust framework supporting multiple communication protocols.

I also developed TypeScript and NestJS services for a real-time platform, using REST APIs and WebSockets to serve web and mobile applications. On a banking platform, I implemented Kafka integrations and automated infrastructure provisioning with Terraform.

At NEXTI, I led technical decisions and architectural improvements for the time-tracking calculation engine as Tech Lead. I redesigned time-bank calculations and implemented asynchronous report generation; I'm now deepening my software architecture expertise with the goal of progressing toward a Software Architect role.
