Enterprise reach
ERP modules I built at PayGURU Technosoft are used by more than 9,000 employees across multiple companies every working shift.
Vedansh Vijayvargia
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.
Visitors land, scroll, and leave without ever telling you what they need.
Without a capture and follow-up flow, opportunities slip through the cracks every week.
Anything over three seconds to load feels broken to a modern visitor — and to Google.
Repetitive copy-paste between tools is time your team should be spending on real work.
Orders in one place, inventory in another, customer notes in a chat — nothing reconciles.
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 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
I still touch migrations, queries, and UI polish myself. These figures come from systems I built or maintained, not slide decks.
ERP modules I built at PayGURU Technosoft are used by more than 9,000 employees across multiple companies every working shift.
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.
Client products and internal builds I led end to end — database schema, APIs, admin panels, authentication, deployment, and handover.
I replaced fragile spreadsheets with JasperReports and scheduled pipelines so operations teams get consistent figures on time, without last-minute exports.
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
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, agent frameworks, and webhook automations when a client needs AI in production.
Core focus
LLM apps, RAG, workflow agents (email drafters, approvals), OpenClaw-style integrations, and production APIs clients actually ship.
Foundation
Typed backends and scripts for ERP modules, REST APIs, and dashboards — PHP and Python for heavy logic, TypeScript where the UI and Node services need structure.

Career
Internships in Jaipur and remote, then PayGURU ERP, now Technosmart AI — with freelance sites on the side since 2023.
Services
Clear deliverables and a fixed quotation before we begin — so you always know what you are paying for and what to expect.
One-page site with contact form, mobile layout, and basic SEO — good for a first credible web presence.
Multi-page site plus admin to edit content, capture enquiries, or run simple bookings.
Custom app, ERP slice, or AI feature when SaaS tabs and spreadsheets are no longer enough.
AI agents, chatbots, automations, speed fixes, or monthly maintenance after the main build is live.
Every engagement begins with a written quotation. Anything outside the agreed scope is discussed and approved before any additional billing.
Draft-and-review flows for sales email, support replies, and internal tasks — human approves before anything sends. Built for teams who cannot risk fully autonomous outbound mail.
Agents wired into WhatsApp, Gmail, calendars, CRM, and webhooks so routine work runs on triggers — inbound leads, follow-ups, and handoffs without living in five tabs.
Inbound voice (Retell and similar) plus site chatbots that qualify leads, book calls, and escalate cleanly — one stack, not a separate demo for each channel.
Next.js + Node UIs to edit prompts, watch runs, replay conversations, and tune automations without redeploying code for every wording change.
I scope one painful workflow first — email triage, lead routing, reporting, or a voice line — prove it in staging, then expand. You keep the tools you already pay for.
