Varun Kothari

Full Stack Web Developer

I build production-grade web applications end to end — from architecture and APIs to deployment and the live production fixes that follow. By day I ship the kiosk platform's mobile web experience at Zuchiz; after hours I run Echoaxia, an AI-powered feedback SaaS I founded and built solo.

Echoaxia — AI-powered feedback SaaS, founder

Go, for backend microservices

01 · About

Own the whole thing.

I'm a full stack developer based in Bengaluru with a simple operating principle: own the whole thing. At Zuchiz, I built the mobile web version of the company's kiosk platform from scratch — Angular with NgRx Signal Store, REST APIs, SQL schema design and optimization — and carried it through to production deployment. That end-to-end ownership earned me the company's Individual Excellence Award.

Outside the day job I wear a founder hat. I created Echoaxia, an AI-powered anonymous feedback SaaS that grew out of my MCA research project — I handle everything from the Next.js codebase and sentiment-analysis features to the public API, product strategy, and user support. I've also designed, built, and now operate a production e-commerce platform for a tea brand, complete with live Razorpay payments and automated Shiprocket logistics.

My toolkit is TypeScript-first: React and Next.js — or Angular — on the front end, Node.js and Express behind it, PostgreSQL or MongoDB underneath, and Docker with GitHub Actions to ship it. I care about clean, readable code, fast pages, and root-cause fixes over quick patches, and I use agentic AI tools like Claude Code and Gemini CLI to move faster without lowering the bar. Currently learning Go for backend microservices.

Own it end to end

Architecture, build, deployment — and the production fixes after.

Root cause, not quick patch

Debugging means finding the why, not silencing the symptom.

Performance is a feature

Fast pages and lean queries are part of the definition of done.

AI-accelerated, human standard

Agentic tools speed me up; the quality bar stays where it is.

Products I've designed, built, and operated — most of them solo, several of them live in production.

echoaxia

Founder & DeveloperLive2025 — Present

Echoaxia

AI-powered feedback SaaS

An anonymous feedback platform that turns raw responses into signal. Echoaxia began as my MCA research project and became a product: people collect honest, anonymous feedback through shareable links while AI-driven sentiment analysis surfaces the patterns worth acting on — all run end to end by a solo founder.

AI sentiment analysis on incoming feedback
Anonymous collection with advanced security
Public REST API with API-key management
Third-party embed for review collection
Transactional email via Resend

The hard part

Turning a research prototype into a hardened product — exposing a public API that is safe for third-party sites to embed, with key management and abuse protection designed in from the start.

Verdella Tea

Production e-commerce platform

A production e-commerce platform for a tea brand, built and operated end to end by one developer. Verdella handles real customers and real money — live Razorpay payments, automated Shiprocket shipping and tracking, authenticated accounts, product offers, and customer reviews — with deploys, monitoring, and database operations managed solo.

Razorpay payment gateway with live transactions
Automated shipping & order tracking via Shiprocket
Secure authentication with Better Auth
API rate limiting and security with Arcjet
Cart, product offers, and customer reviews

The hard part

Being the only engineer on a system that takes payments — security, uptime, and safe schema changes had to be designed for up front, not patched in later.
