Hi there, I'm Kaushik! 👋

Data Engineer & AI Systems Builder

I build end-to-end data systems that transform raw, unstructured data into production-ready insights.

My focus:

  • Designing scalable data pipelines
  • Leveraging LLMs for real-world extraction & automation
  • Deploying cloud-native, full-stack data products

Currently based in Melbourne, Australia

Featured Projects

NutriScan — Full-Stack AI Nutrition Tracker (Personal Project)

https://nutritional-tracker-delta.vercel.app/

A production-ready full-stack application that extracts and tracks nutritional data from food label images using multimodal AI.

Core Implementation

  • Built a full-stack web app using React (Vite) and FastAPI (Python) leveraging Google Gemini 2.5 Flash for multimodal nutrition data extraction
  • Implemented a client-side image preprocessing pipeline (crop, grayscale, resize) to reduce payload size and improve model accuracy before upload
  • Designed a PostgreSQL schema (7 tables) on Neon, integrated via psycopg2 with automatic table provisioning on backend startup
  • Integrated Supabase Auth (OTP email + Google OAuth) with server-side JWT verification (PyJWT, RS256/HS256) and enforced per-user rate limiting (10 AI calls/day)
  • Stored raw and processed images on AWS S3, with primary/fallback model retry logic and timeout handling across Gemini API calls
  • Deployed frontend on Vercel and backend on Render, with a responsive Material Design 3 UI using Tailwind CSS v4 (mobile bottom-nav + desktop top-bar)

Engineering Focus

  • Real-world multimodal AI integration in production systems
  • Efficient client-side optimization to reduce LLM cost and latency
  • Secure authentication + rate limiting at API level
  • Fault-tolerant external API orchestration with retry strategies
  • Full-stack deployment with cloud-native architecture

AI Skill Recommender & Parsing Pipeline (Internship)

High-volume hybrid inference system for deterministic and semantic skill mapping.

Tech Stack: FastAPI, Python 3.13, Sentence-Transformers, AWS Cognito, SQLite

Architecture: Dual-pipeline system combining:

  • Deterministic parsing (structured extraction)
  • Skill Graph + Hybrid Inference (semantic discovery)

Engine Modes:

  • Deterministic (rule-based precision)
  • Hybrid (fusion)
  • AI-only (embedding-driven discovery)

Mathematical Core:

  • Log-scaled evidence weighting
  • Confidence calibration
  • Feedback-driven ranking optimization

Impact:

  • Drift monitoring
  • Offline evaluation (Precision / Recall / F1)
  • Recruiter outcome-based learning loops

Focus: Production-grade system design including:

  • JWT authentication (Cognito)
  • Async job queues
  • LLM-based output refinement
