• Multi-tenant REST API: Architected a tenant-scoped, data-isolated REST API in Node.js and Express serving multiple organizations securely, with isolation enforced across every MongoDB query and endpoint.
• AI Agent Orchestrator: Designed an orchestrator running configurable multi-step assessment pipelines across 35+ specialized agents through a unified gateway with path-based routing.
• Decision pipeline engine: Built a weighted scoring engine (D1-D9 dimensions) with automated qualification gates and multi-phase flows (assessment, voice screening, one-sided interviews).
• React frontend integration: Integrated backend services with the React.js frontend by wiring API contracts into candidate and recruiter dashboards, fixing UI and state-handling bugs, and refining data-rendering components for the assessment flows.
• Async resume pipeline: Engineered an AWS SQS-based parsing pipeline for bulk uploads of 50+ files with S3 storage, entity-extraction callbacks, and candidate portfolio generation.
• AI-powered JD workflow: Developed an agentic job-description creation flow using async callbacks, status polling, and background monitoring, surfaced through the React UI.
• ATS integration and auth: Implemented ATS sync of applications and candidates with deduplication and job-description linking; designed cookie-based JWT authentication with auto-renewal and RBAC across 4 roles and 8 permission modules.
• One-Sided Interview (OSI) system: Created public token endpoints for S3 video uploads with anti-cheat tracking and AI evaluation, plus a Dropbox OAuth resume-ingestion handshake.
• Voice assessment and low-level design: Built a voice screening pipeline (transcript analysis, score reconciliation, interview-pack generation) and led low-level design of database schemas, API contracts, and performance optimization.
• Local dev and testing: Stood up a LocalStack S3/SQS environment via Docker Compose and authored endpoint and unit tests with Jest and Supertest using mocked repositories.

• Interview workflows: Engineered multi-level interview workflows supporting scalable, flexible hiring processes for complex organizations.
• React frontend contribution: Resolved React component and integration bugs, connected the React.js frontend to backend REST APIs, and shipped UI fixes for the bulk user/talent modules.
• Codebase modernization: Led a full migration to modern TypeScript standards, reducing technical debt and improving performance and maintainability across the codebase.
• Testing and reliability: Implemented comprehensive Jest unit-test coverage, cutting regression bugs by 30% and boosting backend reliability.
• Real-time notifications: Integrated WhatsApp and SMS APIs for real-time notifications, significantly improving user engagement and communication flows.
• Documentation and onboarding: Authored API documentation and workflow diagrams for the bulk user/talent modules, accelerating developer onboarding and cross-team integration.
• Tooling and deployment: Used GitHub Copilot, Cursor AI, and ChatGPT to raise code quality and velocity; upgraded Node.js from v18 to v20; worked within a microservices architecture using LaunchDarkly feature flags for safe deployments and A/B testing.
