• Architect, design, and build highly scalable, resilient, and high-performance backend systems using Java.


• Lead end-to-end system design for complex distributed systems serving internet-scale workloads.


• Design and implement public REST APIs and internal gRPC APIs with strong performance, security, and reliability guarantees.


• Apply deep DSA expertise to optimize algorithms, data access patterns, and system performance.


• Lead architectural design discussions and establish best practices across teams.


• Identify and eliminate scalability bottlenecks, reliability gaps, and technical debt.


• Drive automation across testing, monitoring, observability, CI/CD, auto-healing, and auto-scaling systems.


• Own complex cross-team initiatives as a Single-Threaded Owner (STO) or Technical Lead.


• Conduct high-quality code reviews and mentor senior engineers.


• Provide technical direction on build vs buy decisions through comparative technology evaluations.
