Architected the Node.js backend for a multi-tenant smart asset monitoring platform (Omnisense); engineered TCP/UDP data ingestion servers processing 10,000+ daily streaming GPS and ultrasonic telemetry data points into MongoDB. • Built robust server-side processing logic to integrate Gemini Computer Vision models for an old electronics reward system project; handled continuous item state validation and indexing classification payloads into high-throughput NoSQL layers. • Programmed automated background worker processes using Gmail API and node-cron to securely ingest, parse, and extract structured fields from 3rd-party PDFs for Report Gen; scaled transactional delivery layers using an AWS SES shared IP pool overlay. • Designed and optimized a production-grade RAG backend microservice (Sighti) leveraging OpenAI and Pinecone Vector DB to serve context-aware computer vision analytics endpoints with low latency. • Engineered secure RESTful JSON APIs to power dual-fleet logistics ecosystems (Yatraq & DriverSync); built backend modules for real-time geolocation mapping data routing, OTP workflows, and stateful JWT session handlers. • Engineered an administrative backend orchestrator connecting LangGraph/LangChain vulnerability scan pipelines to automate enter- prise Jira ticketing workflows, decreasing manual triage cycles by 60%. • Deployed Prometheus and Grafana alerting stacks to trace latency benchmarks across 20+ mission-critical REST endpoints, preserving a 99.9% system uptime record. • Configured multi-container Docker environments, NGINX reverse-proxy mechanisms, and PM2 process management to achieve zero- downtime microservice updates on AWS EC2 clusters. • Architected a specialized backend parsing tool utilizing Groq inference engines and Sentence Transformers to programmatically parse, isolate, and redact sensitive PII fields from multi-page enterprise legal assets. • Spearheaded server-side code reviews and modular custom middleware frameworks, enforcing SOLID principles and reducing devel- opment cycles for new downstream feature integrations.
