  • +Built Case AI Auto Audit for client Palo Alto Networks, scoring technical support engineers against rules for SLA compliance, PII leakage and troubleshooting quality, with one Gemini 2.5 Flash call per rule on Vertex AI returning structured outputs.
  • +Replaced manual case reviews with daily batch pipelines that produce weekly per-engineer reports and AI-generated improvement plans.
  • +Ran regression evaluation against a hand-labeled golden dataset on every pipeline run, routing disputed verdicts to human-in-the-loop manager review.
  • +Owned features end-to-end across a Python backend, Cloud Spanner, and a Next.js UI embedded in Salesforce LWC.
ReactJsTypeScriptNestJsAWSPostgresSQLTailwindNextJsPythonAzure CloudFast APILiveKitLangGraph
  • +Architected and delivered Metalynk, a B2B platform with 2,000+ active users, owning backend, schema design, frontend and AWS deployment (Next.js, NestJS, PostgreSQL).
  • +Led backend and AI workflows for Orterum, an AI conversational research platform running real-time voice agents (LiveKit, ~50 interviews/day).
  • +Built Orterum's LangGraph multi-agent system (interviewer, planner and synthesizer agents) with shared agent state, RAG and streaming responses; improved concurrent session stability by 25% (FastAPI, Azure Cosmos DB).
  • +Built Tax Uttaram, Deloitte's internal taxation tool; solely designed its role-based access control and built streaming database-to-CSV exports.
  • +Orchestrated async pipelines on AWS ECS, S3, SQS, CloudWatch and EventBridge Scheduler; cut notification failures by 30% with retries and dead-letter queues.
ReactJsTypeScriptAWSMongoDBExpressJsNodeJsSocket IOMaterialUIRabbitMQ
  • +Developed 10+ enterprise modules (Attendance, Payroll, Timesheets, Assets, Leaves, Workforce) for three role-based portals: Admin, Manager and Employee.
  • +Built event-driven microservice messaging with RabbitMQ and Socket.IO for async processing and real-time UI sync.
  • +Spearheaded a platform-level authentication microservice adopted across internal apps, reducing authentication errors by 20%.
  • +Conducted technical interviews for engineering hires and mentored interns.
