What I'm looking for

I’m looking to lead architecture and modernization of scalable SaaS and real-time systems—bringing automation, event-driven design, and strong observability to teams shipping reliable, maintainable products.

Software Engineer and Technical Architect with 12+ years of experience building and consulting teams for scalable infrastructure, data-driven mobile systems and products. I’m skilled at bridging modern software engineering with systems architecture at scale—leading modernization and automation while enabling development across diverse sectors.

Most recently, I led the re-architecture of a multi-tenant SaaS platform, migrating from monolithic to event-driven architectures and designing cloud service decomposition for microservice and containerized deployments. I also strengthened reliability and observability with structured logging, Grafana dashboards/alerting, Prometheus monitoring, and Infrastructure as Code using Docker, Ansible, and CircleCI, while guiding teams through new engineering and documentation standards.
