Full-stack engineer with deep backend, search, and AI infrastructure experience.
Currently building production backend, search, and AI infrastructure at Instahyre. I ship across the stack — from Django + Elasticsearch backends to Node.js microservices, RAG pipelines, and legacy AngularJS frontend systems.
- 🔭 Working on backend, search infrastructure, and AI tooling at Instahyre
- 🤖 Building production RAG systems, MCP servers, and vector search pipelines
- ⚡ Performance optimization: reduced API latency ~50%, cut search p95 from 220ms → 45ms
- 👯 Open to collaborating on open-source projects, backend tooling, and AI infrastructure
- 💬 Ask me about Python, Django, Elasticsearch, RAG, Node.js, or system design
| Area | Highlights |
|---|---|
| Backend & Search | Django, MySQL, Elasticsearch, 40M+ document backfills, query optimization |
| AI Infrastructure | MCP servers, RAG retrieval, ChromaDB, OpenAI embeddings, 90K+ indexed chunks |
| Microservices | Node.js, RabbitMQ, BullMQ, Redis, WebSocket, AWS SQS/SES — latencies from seconds to <80ms |
| Frontend | React, AngularJS, design systems, mobile-first UI, complex directive debugging |
| Performance | 50% API latency reduction, p95 resume upload 6.2s → 180ms |
