I’m a Software Engineer with 3+ years designing and owning scalable backend systems, microservices, and cloud-native SaaS applications in production environments. I focus on measurable performance gains—reducing API latency by 90%+—while building high-availability services that hold up under 3–5× peak traffic.

At GravityOne AI, I engineered a multi-tenant SaaS backend with JWT-based tenant isolation middleware, enforcing secure cross-tenant data boundaries across 30+ business units. I also built a configuration-driven dynamic SQL query builder for aggregation pivot views, cutting dashboard load time from 5.8s to 380ms through composite indexing and a smaller API surface area (∼70% reduction).

I’m especially driven by event-driven and async architectures. I implemented a table-driven workflow state machine with 3-dimensional RBAC permission guards and built async report generation with background job queues and long-polling APIs—eliminating synchronous timeouts on executive reports. I round this out with production observability (structured JSON logging, distributed tracing, and p95/p99 latency dashboards) to support proactive error-budget monitoring.

Previously at UClean, I scaled a traffic-aware booking platform using Node.js microservices and Angular operational dashboards, supporting high concurrency and RBAC admin operations under 3–5× peak-hour spikes. I improved dashboard API response times to sub-50ms using composite indexing, read/write separation, connection pooling, and a Redis cache-aside strategy; I also refactored workflows into async event-driven pipelines to boost responsiveness by ∼40% and stabilize throughput during peak periods.
