Rockstar🎓
Top SchoolAman Mangal is a Staff Software Engineer with 13 years of experience specializing in systems, distributed systems, data engineering, and databases, currently based in Jaipur, India. He has a strong track record stabilizing and evolving production-grade databases—most notably contributing to Dgraph and to Ristretto, a high-performance Go cache born from his work on caching in Go. Aman blends deep low-level engineering (protos, cache internals, bloom filters, TTL, security fixes) with product-minded system design, having led efforts like a Dgraph Kubernetes operator, chaos-ready integration tests, and API key security. His background spans high-throughput data pipelines and optimizations at scale (Spark, Redshift, Aerospike) and network/cloud provisioning systems at Arista, reflecting comfort across storage, compute, and operations. He also volunteers technical leadership for nonprofits, building resilient offline-first event systems and mentoring teams on CI/CD and cloud deployments—an indicator of his practical focus on reliability and real-world constraints.
