I design and build intelligent systems that scale. From robust backend architectures and cloud deployments to cutting-edge machine learning pipelines, I focus on bringing complex engineering concepts to life.
Backend & AI Engineer
Vignana Jyothi Institute of Technology
I build systems that scale — from distributed backends to intelligent AI pipelines. Obsessed with clean architecture, real-world AI applications, and engineering that makes a difference.

Redis for hot data (TTL: 30s). CDN for static assets. Cache-aside with write-through for consistency.
p50 <50ms, p99 <200ms. Cache hit <10ms. DB query <80ms. Budget: 20% network, 30% compute, 50% I/O.
Horizontal via stateless services. DB read replicas. Event-driven async for compute. Circuit breakers at boundaries.
Every system will fail. Design with circuit breakers, retry logic, and graceful degradation from day one.
Cache at the right layer. Redis for hot data, CDN for static, in-memory for computed values. TTL > manual invalidation.
API design is product design. Version from v1, document everything, never break backwards compatibility in production.
Premature optimization is the root of all evil. Profile first, then optimize the actual bottleneck with data.
Tools and technologies I use to build production-grade systems.
