Open to AI, Backend & Full Stack roles

// AI & Full Stack Engineer

I build production AI systems on backends that don't break.

2.5+ years shipping fintech, real-time, and AI-powered systems — LLM integrations, RAG pipelines, payment infrastructure, and event-driven backends with Node.js, TypeScript, Python, Redis, PostgreSQL, and AWS.

Projects

Flagship open-source work aligned with my GitHub profile — GraphRAG, graph data, distributed sync, and production-style backends.

GraphRAG · Repository Intelligence

GraphMind

Self-hosted GraphRAG for codebases — hybrid retrieval and grounded Q&A with file:line citations.

Tree-sitter symbol graphs land in Neo4j before any LLM call — same repo, same structure.
Four-way retrieval fused with RRF: vectors, symbols, keywords, and graph neighbors.
Postgres-backed indexing DAG, dead-code and PR blast-radius views; runs without an API key via deterministic retrieval.

Supply-Chain Risk Explorer · Graph DB

SiliconTrace

Pick any fab worldwide, take it offline, and see which finished products die, revenue at risk, and where to dual-source.

Recursive BOM graph with 515 nodes and 999 relationships across suppliers, facilities, and products.
Blast-radius Cypher traversals rank impacted products by revenue at risk with deduplicated multi-route fan-out.
Shareable impact URLs and CSV exports for blast radius and single points of failure.

GitHub Issues · Outbox / Inbox

Cross-Tool Sync

Bidirectional task sync between a local app and GitHub Issues — durable queues, webhooks, and manual conflict resolution.

Outbox on local writes and inbox for webhooks with checkpointed GitHub backfill.
Last-write-wins with explicit conflict state when both sides change during an offline window.
Docker Compose stack plus a dashboard for sync observability and resolution.

pdf-analyzer · Self-hosted

PDF Page Extractor

Mark pages in a PDF, reorder them, and download a new document — validation on client and server, files stay on your machine.

Thumbnail grid with drag ordering; server assembles output with pdf-lib after magic-byte checks.
Monorepo with supertest API tests and jsdom client tests (30+ cases).
Paper/ink UI themes; selection state survives failed extractions.

Multilingual Construction Assistant

Pyrock AI

Turns informal English/Hindi/Hinglish site messages into structured events while deterministic code owns material inventory math.

Pluggable extraction backends — OpenAI, Anthropic, free OpenCode endpoint, and offline mock — selected by env.
Deterministic stock register where balance always equals received minus used, with durable idempotency.
WhatsApp-style field thread beside the ledger; Zod validation keeps LLM output out of business-state calculations.
