👋 About

I build systems that take data in, run heavy computation, and put the result in front of a user: a model or solver in the middle, a pipeline feeding it, an API and dashboard on top.

Final-year B.Tech IT student at SRMIST Chennai, currently an AI Intern at Applied Systems Research & Technology, leading a small team of undergrads on an AI infrastructure observability platform. I'm especially drawn to the GPU / high-performance computing side: simulation, inference speed, and squeezing more out of hardware.

🎓 Education B.Tech Information Technology, SRMIST Chennai (2023–2027)
💼 Now AI Intern, Applied Systems Research & Technology Pvt Ltd
🎯 Open to AI Engineer · Data Engineer · Forward Deployed Engineer · SDE · GPU/HPC-adjacent roles
📍 Base Chennai, India

🎯 Where I Fit

Role Why Proof
AI Engineer Train, serve, and guard models in real systems YOLOv8 multi-camera pipeline · churn model (ROC-AUC 85.03%) · LLM guardrails in REVORA
Data Engineer Ingest, model, and serve data reliably Relational ETL → MongoDB → star schema · TimescaleDB metrics in AISO
Forward Deployed Engineer Take a messy real-world problem to a working deployed solution Disaster-response platform (SIH 2026) · industrial PPE monitoring · payments recovery app
SDE / Backend Clean APIs, auth, queues, containers, CI FastAPI + Redis + WebSockets + JWT · Docker · GitHub Actions
GPU / HPC Simulation and inference are where I want to go deeper Hydrodynamic + SPH solver pipeline · real-time CV inference · see Roadmap

🚀 Featured Projects

🌊 JalRakshak-HD: Dam-Break & Disaster-Response Intelligence Platform

Smart India Hackathon 2026 · Problem Statement SIH26161 · Team of 6 My role:

A configuration-driven pipeline from dam geometry to breach hydrograph, 2D flood simulation, near-field particle (SPH) simulation, hazard classification, and humanitarian exposure screening, served through a React GIS dashboard. New dams are onboarded with YAML, not code changes.

2D flood model D-Flow FM · 818 km² domain · 30 h simulated · 181 output frames
Near-field model DualSPHysics · ~11K particles · first 1.5 km below the breach
Exposure screening Population, buildings, roads, bridges, critical facilities, 6 response sectors
Engineering FastAPI + React 19 + TypeScript · 57 tests · mass-balance residual 0.0052%
Honesty by design Anything not computed is shown as NOT_RUN, never filled in

FastAPI React 19 TypeScript D-Flow FM DualSPHysics GeoPandas Google Earth Engine Sentinel-1 🔭 Next on its roadmap: on-demand solver runs on an HPC queue and full 3D SPH on GPU.


👷 Worker Safety Detection v2: Real-time PPE Compliance

Multi-camera YOLOv8 pipeline: threaded capture per camera → Redis pub/sub → severity classification → WebSocket alerts to a React dashboard, with JWT + OTP auth, snapshots, email alerts, and one-command Docker deployment.

📉 Telco Customer Churn: Prediction + Executive Dashboard

SQL analytics → EDA → feature engineering → Random Forest → 7-page Power BI dashboard with a retention what-if simulator, on 7,043 customers.

ROC-AUC 85.03% · Accuracy 80.7% · built with a team of 3 SQL Pandas Scikit-learn Power BI DAX


🗄️ Enterprise Data Engineering Pipeline: Multi-Database Architecture

A retail scenario across three storage layers: relational ETL, MongoDB product catalog, and a star-schema warehouse (fact + dimension tables) for analytical queries.

🚗 FuelIQ: Vehicle Intelligence Platform (in development)

Flutter app + FastAPI backend: multi-vehicle garage, fuel-efficiency analytics, service reminders, and on-device OCR receipt scanning. Backed by PostgreSQL 16 (partitioned tables, materialized views), Redis, and MinIO, and documented end to end: PRD → architecture → DB design → scale plan.

⚡ GPU & HPC Focus

What pulls me here: the moment a system stops being "does it work?" and becomes "how fast, and on what hardware?"

Where it already shows up in my work

  • Running physics solvers (D-Flow FM, DualSPHysics) as stages of a larger pipeline in JalRakshak-HD
  • Real-time inference under frame-rate and latency limits in the PPE detection system

What I'm building toward → see Roadmap below.


🗺️ Roadmap

  • GPU vs CPU inference benchmark for the PPE detector (FPS, latency, batch size), then export to ONNX / TensorRT
  • Run the near-field SPH case on GPU and publish timing vs CPU
  • CUDA fundamentals: write and profile a few kernels (reductions, matrix ops)
  • MPI / multi-process basics on a small simulation workload
  • PySpark layer on the data-engineering pipeline
  • Azure deployment + DP-900
  • Harden FuelIQ (tests, CI, deployment)
