What I'm looking for

I seek a senior engineering role building scalable B2B/SaaS platforms with ownership of architecture, mentoring opportunities, and strong DevOps and product collaboration.

I am a seasoned software engineer with over ten years delivering scalable B2B and SaaS platform solutions, specializing in multi-tenant, subscription-based, cloud-native systems.

I architect and build end-to-end solutions from performant React and TypeScript frontends to resilient Node.js/NestJS and Python backend services, emphasizing API-first design, event-driven workflows, and secure payment integrations.

I lead engineering efforts by setting frontend and backend standards, mentoring engineers, driving performance optimization, and owning production systems across AWS and GCP with Terraform, Docker, and Kubernetes.

I prioritize accessibility, test automation, and cross-functional collaboration with product and design teams to deliver customer-facing applications that are reliable, maintainable, and production-ready.
