About
I build systems that scale , not just code that ships. 2+ years engineering production-grade, AI-native platforms at founding-team pace. Primary stack: Node.js + Python on AWS and GCP. Polyglot by necessity, deep by design. 🔗 Github: github.com/shreyescodes | Portfolio: https://shreyescodes.netlify.app/ | LinkedIn: linkedin.com/in/shreyes19| Mail : shreyastc19@gmail.com ━━ What I've shipped ━━ → Workflow Automation SaaS (MERN · BullMQ · WebSockets · Google Workspace) Event-driven backend processing 1,000+ daily jobs with real-time orchestration and persistent queue management. Saved ~3 hrs/user/day. Stateless Node workers on Redis-backed BullMQ, WebSocket push for live status, Postgres for audit trail + replay. Designed multi-tenant cache key namespace to prevent collisions across org boundaries. → Agentic AI Orchestrator (LangChain · LlamaIndex · pgvector · OpenAI · Anthropic) Multi-LLM RAG pipeline with semantic chunking + cosine reranking — lifted retrieval precision ~40%, outperformed Zapier-equivalent flows by 30% in execution speed. Evaluated with RAGAS: faithfulness 0.87, answer relevancy 0.83 in production eval set. → API performance overhaul (Redis · PostgreSQL · Node.js) Read-through caching with TTL-based invalidation and cache warming on deploy. 60% p95 latency reduction. Eliminated redundant DB hits on 80% of read traffic via query plan analysis and N+1 query fixes. → Cloud infra & data pipelines (AWS ECS · GCP Cloud Run · BigQuery · Pub/Sub · Docker) Multi-stage Docker builds cut image size 60%. Staged rollouts with automated smoke tests and rollback gates cut production bugs 25%. Async Pub/Sub pipeline feeds BigQuery for model analytics and RAG context refresh. ━━ Stack ━━ Backend: Node.js · Python · TypeScript · PostgreSQL · Redis · REST · WebSockets · BullMQ Cloud: AWS (ECS · RDS · S3 · Lambda) · GCP (Cloud Run · BigQuery · Pub/Sub) · Docker · CI/CD AI/Data: LangChain · LlamaIndex · pgvector · RAG · RAGAS · OpenAI · Anthropic APIs Learning: Rust (ownership model · systems programming) · Solidity · smart contracts ━━ Background ━━ Best Paper — IETE National Conference. Karnataka Govt (KSCST + IISc) sponsored research. B.E. Electronics & Communications, VTU. Open to: Backend · Platform · AI Engineer · Full-Stack · Software Engineer Bengaluru (on-site) or Remote.
