Chapter 01 : Profile

GAUTAM PAPAT.
AI/ML & FULL-STACK
ENGINEER.

B.Tech AIML student at Walchand College of Engineering, Sangli. Creator of Zenis (Open-Source AI Presentation Engine), eduWin (B2B SaaS Coaching OS), and Parakh (Consumer Health Startup). Focused on deterministic AI, strict unit economics (<$0.005/run), and production software.

Chapter 02 : Core Work

THE THREE MAIN PILLARS.

Three distinct engineering endeavors: an open-source AI engine, a deployed B2B SaaS platform, and a consumer startup app.

[ OPEN-SOURCE AI TOOL ]

Zenis

Ultra-low-token AI presentation generator. Replaces expensive frontier prompts with deterministic scrapers and single-forward-pass System-1 gating to cut token costs by 90%.

Python PyMuPDF BAML React
[ B2B SAAS PLATFORM ]

eduWin

Turn-key operations and financial management blueprint for coaching institutes. Enforces strict tenant isolation with Postgres Row-Level Security and serverless cloud deployment.

FastAPI Postgres RLS Supabase React 19
[ CONSUMER STARTUP APP ]

Parakh

Packaged-product intelligence platform. Scans barcodes and nutrition labels, validating claims against statutory FSSAI & ICMR-NIN thresholds via Gemini 2.0 Flash VLM.

Chapter 04 : Interactive Systems

UNDER THE HOOD.

Interactive architecture simulators directly showcasing my three main projects.

DEPLOYED PROJECTS.

Main Projects
Open Source Tool 01 / FLAGSHIP

Zenis : Low-Token AI Presentation Engine

Deterministic deep research pipeline with sub-$0.005 unit economics.

Offloads 90% of processing from LLMs to open-source scrapers (Trafilatura, PyMuPDF) and lightweight decision models. Uses a two-pass slide reducer and micro-synthesis to hit <$0.005 cost per deck with sub-8s generation.

Python Trafilatura PyMuPDF Chonkie BAML React
B2B SaaS Platform 02 / SAAS

eduWin : Coaching Institute Operations Platform

Multi-tenant management system with strict Postgres Row-Level Security.

SaaS platform for tuition centers covering batch timetables, attendance, and fee tracking. Uses Postgres Row-Level Security for strict tenant isolation and rotating JWT refresh tokens.

FastAPI Postgres 16 (RLS) Supabase React 19 Tailwind CSS
Consumer Startup App 03 / STARTUP

Parakh : Product Label & Safety Scanner

Statutory FSSAI & ICMR-NIN compliance with Gemini 2.0 Flash VLM.

Mobile and web app that evaluates food, beverage, and cosmetic labels against statutory FSSAI and ICMR-NIN limits using barcode scans, package photos, or quick-commerce links.
