Nagaveda Sai Kumar Reddy Gajjala

About

Backend engineer with enterprise SaaS experience (Zoho) who owned an end-to-end cloud integration between Endpoint Central and ServiceDesk Plus, redesigning device onboarding across 64+ scenarios and building a fault-tolerant sync engine that recovered 100% failed transactions. Also built and operated production systems across the stack—FastAPI services with strong testing/observability, React+TypeScript portals, PostgreSQL performance tuning, and AWS deployments with real incident response (RDS CPU saturation resolved with zero downtime).

Key Strengths

• Owned end-to-end cloud integration between enterprise products (Endpoint Central + ServiceDesk Plus)
• Redesigned device onboarding workflow handling 64+ complex scenarios
• Built fault-tolerant bi-directional sync engine with batch recovery (recovered 100% failed transactions)
• Improved reliability and scale via Kafka-based decoupling and Redis caching
• Database performance optimization including indexing and sharding
• Designed production FastAPI service with versioned APIs, JWT auth, RBAC, and standardized error handling
• Strong reliability/observability practice: pytest + Testcontainers, OpenTelemetry tracing, Prometheus/Grafana metrics
• Performance tuning and validation: removed N+1 queries, tuned SQLAlchemy pooling, load tested with Locust
• Designed PostgreSQL schema for vendor communication domain and iterated via query plan + slow query monitoring
• Handled AWS production scaling incident: mitigated RDS CPU saturation using read replicas, query/pool tuning with zero downtime
