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.

// how a build actually goes

Most of my work starts with someone doing the same boring thing every day.

  1. 01

    Find the step that eats the week

    Chasing unpaid invoices. Re-typing orders into a spreadsheet. Setting up the same voice agent by hand for every client. I start by watching how it's done today.

  2. 02

    Write it as plain, readable code

    Small functions, obvious names, no clever tricks. If the next developer can't follow it in five minutes, it isn't finished.

  3. 03

    Ship it, then watch it run

    Tested in staging, deployed properly, and checked against real usage — not just the happy path from the demo.

The code on the right is the core idea behind SmartChase, a reminder system I built: email, then SMS, then an AI voice call, and only then a human.

// selected work · 2023–2026

Things I’ve built that people use every day.

A product I designed myself, plus client sites for businesses in India, Australia and Hong Kong. Every one of these is live, and I built each of them end to end — database, backend, front-end and deployment.

01 · Product

SmartChase

An AI reminder system that does the chasing so accountants don’t have to.

Accounting firms spend hours following up with clients for documents and payments. SmartChase works through it in stages: an email, then an SMS, then an AI voice call through Retell. A person only gets involved if the client still hasn’t responded. I designed and built it, and it has taken most of the manual chasing off our clients’ plates.

bim365.in

A full BIM services platform for architecture, engineering and construction teams in Australia.

Not a template swap — a multi-page PHP site with service pages, city landing pages for local search, a blog, consultation forms, testimonials and WhatsApp hand-offs, with offices in India and Australia. A lot of visitors open it on a phone at a site office, so it had to stay quick on mobile.

03 · Freelance · BIM

bimcrafter.in

A second BIM services website, built on what worked for bim365.

Service pages that explain the work in plain terms, clear routes to a quote, and an SEO-ready structure that’s easy to grow as new services are added. Same approach as bim365: fast on mobile, simple to maintain, and built so enquiries don’t get lost.

thewellnesscode.in website cover

04 · Freelance · Jaipur

thewellnesscode.in

The website for Dr. Shivangi Jain’s doctor-led nutrition and wellness practice.

Programs for nutrition, weight management and metabolic health, a step-by-step “how it works” flow, online consultations, results, FAQs, and a blog and videos section in PHP. Booking happens over WhatsApp and phone, because that’s how her patients actually get in touch.

05 · Freelance · Hong Kong

sourcyn.com

A B2B platform, built and deployed end to end.

Database, backend and a responsive front-end, with structured service content and contact flows so inbound leads are easy to follow up on. I handled everything from the schema to the server.

  • JavaScript

06 · Freelance · E-commerce

shskates.com

An online store for a skate shop that runs without babysitting.

Product catalogue, cart and checkout, plus an admin panel and order management so the owner can run the shop himself. Most customers shop on their phones, so mobile speed was the main brief.

  • PHP
  • MySQL
  • Cart & checkout
  • Admin panel

greenvalleysolar.in

A solar company site with an admin panel the team runs themselves.

E-commerce and admin controls, deployed on cPanel/GoDaddy with SSL and automated backups, so nothing depends on me being online.

// about

The developer who turns the demo into the real thing.

I’m Vedansh, a full-stack developer in Vadodara. For three years I’ve built the parts people actually depend on — ERP screens thousands of employees log into, client sites that load on a site-office phone, and AI agents that make the follow-up call so nobody on the team has to.

Right now I’m at Technosmart AI, where I built the dashboard our team uses to set up and manage AI voice agents for every client. Before that I spent almost two years at PayGURU Technosoft on an ERP platform used by companies like Gujarat Fluorochemicals and Lanxess — which is where I learned that a slow query is a real person waiting.

Outside the day job I take on a few freelance projects at a time: scoped in writing, built in the open, and handed over so you’re never stuck with me.

What the work did once real people used it.

Figures from the PayGURU ERP platform, where I owned modules from schema to screen.

9,000+

people log into the ERP platform I engineered

Across 5+ client companies, including Gujarat Fluorochemicals and Lanxess.

~40%

less query time

Rewriting and indexing the SQL behind the slowest screens.

~80%

faster page loads

Same modules, same users — just less waiting.

10+

ERP modules delivered

HRMS, finance, inventory and the pieces that connect them.

30+

JasperReports built

Report prep time cut by about half; no more Friday exports to Excel.

Backend engineering

Where most of my hours go: the APIs, data models and background work that keep a product honest when real users show up.

  • Node.js & ExpressAPIs and the voice-agent platform backend at Technosmart
  • PHP (OOP)The PayGURU ERP and most of my client sites
  • REST API designAuth, roles and permissions, third-party integrations, webhooks
  • MySQL, PostgreSQL, MongoDBData modelling, indexing, and fixing the slow query nobody wants to touch
  • Redis, queues & jobsCaching, background processing, work that shouldn’t block a request

// ai lab

Below the API call.

At Technosmart AI I ship voice agents to production. Alongside that, I’ve been fine-tuning small open-weight models — Gemma 2B and 7B, Mistral 7B — to understand what actually happens when a model learns something new. This is the loop I run.

Voice agents

Inbound support lines on Retell AI with per-client prompts, set up from a dashboard instead of by hand. Live at Technosmart AI.

production

Workflow agents

Follow-ups that escalate on their own, like SmartChase. A person steps in only when the automation runs out of road.

production

Control dashboards

Next.js panels where non-technical staff edit prompts, switch flows on and off and manage clients without a deploy.

production

The fine-tuning loop

Seven steps, from raw conversations to a model answering inside an app. Scroll to run it.

  1. 01

    Collect and clean the data

    Real conversations are messy. Dedupe, fix encodings, throw out the junk. Most of the quality is decided here.

    hands-on
  2. 02

    Anonymise it

    Names, numbers and anything personal get stripped or replaced before a single training step runs.

    hands-on
  3. 03

    JSONL, then tokenise

    One example per line in the chat format the model expects — then check how the tokenizer splits it, because tokens drive cost, context and memory.

    hands-on
  4. 04

    Configure LoRA / QLoRA

    Learning rate, batch size, gradient accumulation and epochs, chosen around what the GPU can hold. A 4-bit base is what makes a 7B model fit at all.

    experimenting
  5. 05

    Watch the loss, then evaluate

    Training and validation loss side by side, then the tuned model against the base on held-out prompts. Lower loss alone doesn’t mean better answers.

    experimenting
  6. 06

    Save, quantise, serve

    Keep or merge the adapter, reload it to be sure it works, quantise for inference and run it locally through Ollama.

    experimenting
  7. 07

    Wire it into an app

    The part I do every day: model inference behind an API a product can depend on, with timeouts, fallbacks and logs.

In their words.

Four of the people I’ve built for, on what they actually got.

bim365.in01 / 04
Vedansh built the whole bim365.in presence — service pages, city SEO, blog, testimonials and consultation forms. It’s a proper multi-page product, not a template swap. Mobile speed mattered because our clients open it from site offices.
Naman VijayFounder, BIM365 · Jaipur
sourcyn.com02 / 04
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 compared to our old site.
Bobby BarotFounder, Sourcyn · Hong Kong
shskates.com03 / 04
The skate shop site handles catalogue, cart and checkout without us babysitting it. Mobile performance was the main ask — that part delivered.
Anshul VijayOwner, SH Skates · Bhilwara
mantriitsolutions.com04 / 04
mantriitsolutions.com explains our services without clutter. Enquiries come through one form instead of scattered DMs.
