Generation Llama 3.3 70B via Groq · SSE streaming · 0–100 confidence scoring
Chunking Heading-aware (350–500 tokens) · 10-rule generation protocol
Latency Sub-200 ms retrieval · zero external API calls in search path
Infra Single Docker multi-stage image (Node 20 + Python 3.9) · admin analytics · live re-ingestion

⚡ API Health Monitor

Concurrent endpoint health-checking engine — retry logic, timeout propagation, bounded-latency execution

Repo Stack

  • Native Go concurrency for parallel monitoring with zero external dependencies
  • Retry + timeout propagation ensuring bounded-latency under load

⚙️ Premium Online Judge

Full-stack competitive programming platform — Kubernetes-native, Redis-streamed, Docker-sandboxed

Repo

  • cgroups + SECCOMP sandbox · Redis Streams decoupled eval pipeline
  • Live contests · leaderboards · submission analytics · rating system

🏆 Competitive Programming

📌  LeetCode       Knight · 1200+ solved · 88% acceptance · 365-day streak
📌  Flipkart GRiD  Round 3 cleared
📌  AlgoU Camp     Top 0.5% nationally

🎓 B.Tech Thesis

UAV-Assisted Obstacle-Aware Data Collection for Resource-Constrained IoT Networks
Supervisor: Dr. Ankur Jaiswal · ABV-IIITM Gwalior

  • 800×600 m IoT deployment — 20 nodes, 3 cuboid obstacles (heights 128–148 m > UAV altitude 100 m)
  • Greedy dominating-set selection → 65% node compression (20 → 7 stops, 100% coverage)
  • Visibility-graph routing → collision-free paths (~2566 m, 9.2% battery)
  • D3QN agent for adaptive path optimisation — state encodes UAV pose, residual energy, obstacle proximity, RP visit vector
  • PPO as continuous-action extension
