Hi, I'm Nishant 👋

Backend & AI systems engineer. I build distributed backends in Go and Python, and LLM systems that I measure instead of just demo. Currently at Culinda Inc. Open to SWE / AI engineering roles.

Project What it is Proof
Guarded Agent Ensemble LLM agent wrapped in 4 defenses adapted from agent-safety papers, A/B evaluated with a composite index 733 tests; on AgentDojo held-out banking, attack success 39/72 → 0/72; reports where the defenses hurt a strong model
RidePulse Event-driven ride matching in Go · Kafka · Redis GEO · Prometheus ~400 RPS intake, successful-match p95 33–84 ms; written-up race-condition and deadline fixes
Lumen AI money advisor: invoice reading, text-to-SQL agent, hybrid RAG Live demo · retrieval top-5 hit rate 67 → 100 / 104 with BM25 + reranking
EchoLine Offline real-time captions for anything playing on Windows Caption latency p50 266 ms / p95 438 ms; installer shipped via GitHub Actions releases
SpatioX C++17 spatio-temporal index (KD-tree + time index) with Python bindings 5–20× faster than a linear scan at 1k–50k records
