What I'm looking for

I’m looking for a role where I can build cloud-native, distributed products end-to-end—owning architecture, performance, and observability. I want to partner with stakeholders to scope, design, and ship reusable solutions, ideally across web and scalable backend systems.

I’m a Full-Stack Software Engineer with 5 years building distributed, cloud-native systems in production. I operate a banking platform at scale (400K+ requests/min), owning backend architecture, web interfaces, observability, and performance.

I also build and run a marketing automation SaaS that generates ad creatives with AI and publishes campaigns through the Meta Ads API. I enjoy designing event-driven, reusable capabilities that turn stakeholder needs into shipped solutions.

I bring deep experience with Google Cloud, React, and modern Cloud & DevOps practices, including Kubernetes, Docker, and CI/CD. I’m hands-on with observability (OpenTelemetry, Prometheus, Grafana, AlertManager) and architecture practices like Clean Architecture, DDD, CQRS, SOLID, and TDD.
