HARSHIL RAO

I engineer order out of unconventional ideas. Sitting at the intersection of vastly distinct disciplines, I build the strategy and write the code for zero-to-one ventures. Let me show you how.

01 // Polymath Profile

Engineering across hardware, full-stack web, and autonomous AI.

I'm an Electronics & Computer Engineering student at Atharva College of Engineering, building AI-driven software across web, voice, and automation. My work sits at the intersection of hardware and software — from embedded systems to full-stack web apps to real-time AI voice agents.

Alongside my degree, I co-founded two early-stage ventures — SAAR AI and Zhessor — architecting autonomous AI systems, B2B growth infrastructure, and zero-to-one products. I gravitate toward problems that combine business strategy with multi-disciplinary engineering.

THE THREE PILLARS

How I build & operate

Developer

Full-stack, embedded, and AI engineering across web platforms, computer vision, and real-time voice AI — shipping production systems from scratch.

Polymath

Synthesizing electronics, software architecture, AI automation, and market strategy — connecting distinct disciplines where the most asymmetric opportunities live.

Founder & Businessman

Co-founder of SAAR AI and Zhessor — building custom B2B AI agent systems, voice pipelines, and scalable growth engines for modern businesses.

CAMPUS SOCIAL PLATFORMSYS_01 // FOUNDER & DEVELOPER · DEPLOYED

Promform

Impact & Result

300 sign-ups within 4 days of launch. 3 couples independently reached out to confirm the platform helped them find their prom partner.

A campus-exclusive web platform that eliminates the social friction of finding a prom partner — turning an awkward cold-outreach problem into a seamless, preference-matched experience for college students.

COMPUTER VISION WEB APPSYS_02 // FOUNDER & DEVELOPER · DEPLOYED

Anipic

Impact & Result

74% cosine similarity accuracy across 9 AI-generated animal classes. Zero model fine-tuning — purely deterministic facial geometry matching.

A computer-vision web app that uses facial geometry embeddings and deterministic cosine similarity scoring to match any uploaded photo to its closest animal look-alike — no random quizzes, real geometric math.

B2B AI OUTREACH & BOOKINGSYS_03 // FOUNDER & DEVELOPER · DEPLOYED

WhatsApp Automation Agent

Impact & Result

35% increase in lead-to-meeting conversion. Average lead response time slashed from 4 hours to under 15 seconds via instant AI-driven WhatsApp engagement.

An AI-driven B2B outreach, qualification, and booking engine built on WhatsApp — instantly engaging high-intent leads the moment they enter the funnel, qualifying them through multi-turn conversation, and autonomously scheduling discovery calls.

EXECUTION METHODOLOGY

From Unconventional Idea to Shipped System

Initiate a Conversation
01

Thesis & First-Principles Discovery

Identify the asymmetric bottleneck, market leverage point, and whether a software platform, AI agent, or hardware-software system creates the strongest moat.

02

System & Venture Architecture

Design a lean, high-reliability technical and operational blueprint — mapping data flows, AI pipelines, and user acquisition mechanics before writing boilerplate.

03
