Nilabja Bhattacharya — Senior Software Engineer
I'm a Senior Software Engineer with 5+ years of experience architecting and scaling backend security infrastructure that protects platforms serving millions of users. At Salesforce, I own performance validation and observability for Vault-based secrets management on GCP — ensuring cryptographic infrastructure sustains 3,000+ RPS with enterprise-grade reliability. Previously at PhonePe, I architected a unified AuthN/AuthZ platform from 0-to-1 that sustains 1K RPS at P99 latency of 50ms with auto-scaling, and designed a PKI system managing 100K+ certificates across 40K+ hosts. My technical depth spans Go, Java, and Python, with hands-on ownership of distributed systems built on Kafka, Redis, Elasticsearch, and MySQL. I operate at the intersection of security and performance engineering: designing systems that are both hardened and fast. From capacity planning and SLO definition to load testing and failure-mode analysis, I ensure critical security services don't just work — they work under pressure. Before security infrastructure, I shipped high-performance open-source database drivers at Oracle that reached thousands of production environments globally. I lead by raising the bar around me. I've coordinated cross-team delivery of shared platform services, driven technical roadmaps from 0-to-1, established observability standards that cut operational incidents, and mentored engineers on building production-grade systems. I thrive in ambiguity — give me an unsolved infrastructure problem and I'll deliver a system that scales.
