I’m a Staff Engineer with 12+ years of experience in backend engineering and distributed systems, primarily in AdTech. I’ve designed and scaled high-performance platforms handling millions of requests per second, with deep expertise in Java, Spring Boot, microservices, and cloud-native systems (GCP, AWS, Kubernetes). On Topmate, I can help you with: System Design & Scalability — how to approach large-scale, low-latency systems. Backend Engineering Guidance — writing clean, efficient, production-ready code. Career Prep — mock interviews, resume feedback, and transitioning to senior/staff roles. Mentorship — guidance on growing as an IC, or preparing for high-growth/startup environments. If you’re preparing for interviews, building scalable systems, or navigating your career path as a backend engineer, I’d be glad to help.
