Vedansh Vijayvargia

AI/ML & Full Stack Developer building production systems that actually ship.

I build and maintain software that has to survive real users — ERP modules, client websites, AI dashboards, and LLM hooks. Based in Vadodara; remote across India, Australia, and elsewhere.

Your website is live, but your operations still run on spreadsheets and goodwill.

A site that looks great but does not convert

Visitors land, scroll, and leave without ever telling you what they need.

Leads scattered across WhatsApp and email

Without a capture and follow-up flow, opportunities slip through the cracks every week.

Slow pages that quietly cost you traffic

Anything over three seconds to load feels broken to a modern visitor — and to Google.

Your team is the CRM

Repetitive copy-paste between tools is time your team should be spending on real work.

No single source of truth

Orders in one place, inventory in another, customer notes in a chat — nothing reconciles.

Ten SaaS subscriptions, zero ownership

Monthly fees keep growing, but you still cannot customise the workflow you actually need.

You do not need more landing pages. You need a system that behaves predictably — ideally one with AI doing the repetitive work.

I write code for the moment after the demo — when 9,000+ real users click “Submit” and expect the system to deliver.

I am Vedansh Vijayvargia, an AI/ML and Full Stack Developer based in Vadodara, Gujarat. I currently work full time at Technosmart AI (internal product work is not shown here). Freelance and client sites below are what I can discuss publicly.

Before Technosmart, I spent nearly two years at PayGURU Technosoft shipping enterprise ERP modules — HRMS, payroll, finance, and inventory — for Gujarat Fluorochemicals, Lanxess, Inox Wind, MG Hector, and other large Indian businesses. That is where the 9,000+ daily-user number comes from, not LinkedIn maths.

I have also been freelancing since 2023 for clients across India and Australia, with most engagements coming from repeat work and referrals. My background combines a B.Tech in Computer Science (AI specialisation) with three years of hands-on production experience.

By the numbers

Three years of ERP, full stack, and AI work — the parts that show up in production.

I still touch migrations, queries, and UI polish myself. These figures come from systems I built or maintained, not slide decks.

0

Enterprise reach

ERP modules I built at PayGURU Technosoft are used by more than 9,000 employees across multiple companies every working shift.

0

Production tenure

Three years of owning features end to end across PHP, JavaScript, React, Next.js, and Node.js — with releases tested and deployed properly, not pushed straight to production.

0

Launches I owned

Client products and internal builds I led end to end — database schema, APIs, admin panels, authentication, deployment, and handover.

0

Reporting stack

I replaced fragile spreadsheets with JasperReports and scheduled pipelines so operations teams get consistent figures on time, without last-minute exports.

0

Repeat freelance work

Every freelance client who stayed past the first delivery either booked phase two or sent a referral. No churn yet on long jobs — I keep scope and timelines explicit so surprises do not kill the relationship.

Expertise

AI/ML & Full Stack Developer Skills

What I use week to week: PHP and MySQL for ERP, Next.js and Node for dashboards, Python where ML shows up, plus OpenAI, Claude, and Retell when a client needs AI in production.

Languages — PHP, JavaScript, TypeScript & more

Python TypeScript JavaScript (ES6+) Node.js Core PHP HTML5 CSS3

Frontend — React, Next.js & modern UI

React Next.js Bootstrap AJAX jQuery Responsive Design

Database — MySQL, MongoDB & optimization

AI work I ship from Vadodara — voice agents, dashboards, and the glue between your tools

Voice agents on inbound calls

Retell AI setups that answer FAQs, capture lead details, and hand off to a human when the script says so — not a demo that hangs up on real callers.

Dashboards your ops team can run

Next.js + Node panels to tweak prompts, watch call logs, and trigger webhooks without opening Postman every afternoon.

APIs and small automations

Webhook bridges between WhatsApp, CRM, sheets, and your existing ERP — the boring pipes that stop people copy-pasting between tabs.

For freelance clients I scope one painful workflow first (calls, bookings, or reporting), prove it in staging, then expand. You keep the tools you already pay for.

Testimonials

What clients and teams say about working with me

★★★★★
About a month from brief to live — product pages, enquiry form, mobile layout. SEO picked up slowly (as it does), but inbound leads are clearly up versus our old site.

★★★★★
Vedansh built the whole bim365.in presence — service pages, city SEO, blog, testimonials, and consultation forms. It is a proper multi-page product, not a template swap. Mobile speed mattered because our clients open it from site offices.

The skate shop site handles catalog, cart, and checkout without us babysitting it. Mobile performance was the main ask — that part delivered.

Canberra to Vadodara time zones were fine — async updates, clear milestones. The new site looks like a proper trade business; we get more enquiries than the old DIY page.
