πŸ‘‹ Hey, I'm Gourab Das

Software Developer | Backend Engineer | AI Engineering

I’m a Software Developer with ~3 years of experience building scalable backend systems, distributed applications, and AI-powered products.

I enjoy solving challenging engineering problems β€” from designing multi-tenant architectures and high-throughput data pipelines to building RAG, semantic search, and agentic AI workflows.

I’m not tied to a particular framework or language. I focus on understanding the problem, choosing the right tools, and building systems that are reliable, scalable, and maintainable.


πŸš€ What I Work On

  • βš™οΈ Backend Engineering β€” Python, Java, Django, Flask, Spring Boot, REST APIs & Microservices
  • πŸ€– AI Engineering β€” LangGraph, LangChain, RAG, Hybrid Search & AI-powered applications
  • πŸ” Search & Retrieval β€” OpenSearch, Milvus, semantic search, reranking
  • πŸ“Š Large-Scale Data Systems β€” ClickHouse, Neo4j, Kafka & distributed data processing
  • 🏒 Multi-Tenant Systems β€” tenant isolation, RBAC & organization-aware architectures
  • ☁️ Cloud & Infrastructure β€” AWS, Docker, NGINX, Linux & CI/CD
  • πŸ–₯️ Full-Stack Development β€” React, Next.js, TypeScript & Tailwind CSS

🧠 Things I've Built

πŸ”Ž CrimeGPT β€” AI Investigation Search

Built an AI-powered investigation search system for querying criminal databases and FIR records using natural language.

  • Built LangGraph-based query orchestration for structured and semantic retrieval workflows.
  • Processed 5,000+ investigation queries through the orchestration layer.
  • Integrated OpenSearch and Milvus for structured and semantic retrieval.
  • Optimized semantic search over 600K+ FIR records.
  • Implemented retrieval workflows for investigation-oriented search and analysis.

πŸ“‘ Telecom Intelligence Platform

Built a tool-driven natural-language investigation workflow for analyzing telecom records.

  • Enabled investigation across 1B+ telecom records.
  • Dynamically invoked analytical tools based on natural-language queries.
  • Built workflows for extracting insights from telecom and network metadata.

πŸ“Š Large-Scale Intelligence & Analytics Platform

Designed backend systems for processing and analyzing large-scale intelligence data.

  • Built a 100M+ record precomputation pipeline with historical backfills and recurring updates.
  • Generated suspect-level aggregates in ClickHouse, reducing API latency by 50% by eliminating expensive runtime joins.
  • Designed Neo4j graph models spanning 200M+ entities and 314M+ relationships.
  • Exposed graph, linkage, and geospatial analytics through Django REST APIs.
  • Designed a multi-tenant architecture supporting 4+ agencies with tenant isolation, RBAC, and tenant-aware request filtering.
