G. Karthik Koundinya - AI and backend engineer

Portfolio LinkedIn Email Resume CodeChef ranked 6 India and 76 global LeetCode 2665 Guardian

Building AI Systems That Hold Up

I work at the intersection of applied AI engineering and backend systems: agentic workflows, RAG pipelines, evaluation, retrieval, APIs, latency, and reliability.

I am looking for roles around AI Engineering, Applied AI Engineering, AI Software Engineering, and Backend Engineering for AI products.

Signal Proof
Agentic systems LangGraph support triage, multi-agent supply-chain monitoring, evaluator work in Google ADK
Retrieval and grounding BM25 + dense retrieval, reranking, citation validation, source-linked answers
Backend depth FastAPI/Flask/Node APIs, async processing, PostgreSQL/Supabase, MongoDB, Cloud Run, AWS EC2
Competitive programming CodeChef #6 India / #76 Global, LeetCode 2665 Guardian
Open source 21 PRs counted across merged and active work in AI, data, devtools, and infrastructure repos

Systems Worth Opening

Project Why it matters
Grounded Support Triage Multi-domain support agent with LangGraph routing, hybrid retrieval, deterministic citation checks, escalation fallback, traces, and eval tooling.
EdgeSentinel Edge-native bot detection using Cloudflare Workers, Durable Objects, KV, D1, Vectorize, Workers AI, and OpenAI fallback.
Lumina Search Hybrid RAG/search engine with FAISS, BM25, SQLite content-hash caching, AsyncIO backend, and transparent scoring.
SupplySentinel Autonomous multi-agent supply-chain risk monitor with confidence loops, deduplication, and Cloud Run deployment.
TurboQuant KV Cache PyTorch implementation of KV-cache compression with reproducible benchmark artifacts and quality/throughput tradeoff reports.
PinPoint AI Flutter logistics app with exact pins, saved locations, voice notes, push notifications, agent claiming, and AI-assisted rider guidance.

More public work: Antim, Lecture Voice-to-Notes, AI Network Traffic Shaper, College Lost & Found, UML Designer AI, productionize.
