Founding Engineer

Promoted

Jul 2018Present · 7 yrs 11 mos

  • As the founding engineer at Observe.AI, I played a pivotal role in architecting and building the core enterprise platform and data infrastructure that became the backbone for all AI-driven products. My work spanned platform architecture, data pipelines, and early product development — transforming the initial concept into a scalable enterprise-grade system.
  • Enterprise Platform -
  • Built a full-scale identity and access management system supporting users, CSMs, and external applications, leveraging OAuth and modern security standards.
  • Enabled enterprise compliance and certifications (ISO, PCI, SOC2) by implementing secure policies, audit frameworks, and data protection mechanisms across the platform.
  • Designed and developed account and user management systems, forming the foundation for multi-tenant operations and RBAC-driven authorization.
  • Data Ingestion Pipeline -
  • Architected and implemented a high-throughput data ingestion pipeline to acquire call recordings and metadata from diverse enterprise sources (SFTP, S3, APIs, etc.).
  • Designed a modular, scalable processing framework to extract both ML-based and rule-based insights from millions of post-call recordings.
  • Built the foundation that powers Observe.AI’s data-driven intelligence layer — ensuring reliability, security, and extensibility for large enterprise customers.
