I’m a staff-level backend engineer with 7+ years of experience in system design, distributed systems, and multi-tenant SaaS platforms. I’ve built high-availability, fault-tolerant, event-driven systems with real-time communication and scalable backend services, consistently taking production ownership.

At SupportLogic, I owned staff-level architecture for a multi-tenant, distributed multi real-time notification platform, designing tenant isolation, data partitioning, and horizontal scalability for 20+ tenants. I built asynchronous event-processing pipelines handling 20k+ records per cycle with ~300 downstream API calls, reducing end-to-end latency by ~60%, and I contributed to high availability and fault tolerance of real-time workflows.

Across 91Social and Athmin Technologies, I defined backend architecture and scalability strategies, improved database performance by ~20% with schema redesign, indexing, and Redis caching, and mentored 4–5 engineers. I also architected WebSocket-based real-time systems, delivered secure 1:1 and group chat with presence and sessions, and led teams of 3–4 engineers—bringing strong cross-team leadership, mentoring, and technical escalation to every release.
