Hire the developer who built this site
You just did that by hand.
I can make it automatic.
These 182 tools are free and always will be. But if you are opening one of
them every week — resizing the same batch of photos, cleaning the same messy
export, copying the same figures between sheets — that is not a tool problem
any more. That is a script you do not have yet.
I am Chaman Raj R. I built this site and every tool on it, solo, from
Chennai. I also take on paid work: Python automation, web scraping, AI chatbots
and spreadsheet systems.
- 96,000+downloads across my products
- 182tools on this site, all built by me
- 75+countries using them
- 6public repositories, MIT licensed
The one rule I work by
I only take work I can check myself before I deliver it.
I run your script on your real sample data. I open the spreadsheet and verify the
totals. I talk to the chatbot before you ever see it. If something is broken,
I am the one who finds out — not you, and not your client.
It is also why I turn work down. If I cannot verify it, I will tell you so instead
of taking the money and hoping.
01
Four things I build
01 Python scripts that do the boring work
If you open the same tool on this site every week, that is a script waiting to be written.
What you get: A commented Python script, setup notes written for a non-programmer, and a double-click .exe if you do not want to install Python.
- Batch-process hundreds of files in one run
- Merge, clean and reformat Excel and CSV data
- Rename, convert and sort files automatically
- Pull data from any API on a schedule
- Generate reports and email them out
02 Web scraping into a clean spreadsheet
Product prices, business directories, listings, reviews, competitor data — turned into a file you can actually use.
What you get: Deduplicated data as Excel, CSV, JSON or Google Sheets — plus the scraper itself, so you can re-run it whenever you want.
- E-commerce prices, stock and product listings
- Business directories and contact lists
- Job boards, marketplaces and classifieds
- Reviews, ratings and competitor tracking
- Pages behind pagination or JavaScript
03 An AI chatbot trained on your own content
Not a generic bot with your logo on it. One that answers from your docs, your FAQs, your product catalogue.
What you get: A working chatbot and the full source code. You own it outright — no monthly fee to me, ever.
- Embedded on your site, matched to your branding
- Trained on your documents so it stops inventing answers
- Streaming replies, mobile-ready, proper error handling
- Works with GPT, Claude, Groq, Gemini or a local model
- API key kept server-side, never exposed in your page
04 Excel and Google Sheets that run themselves
Formulas that work, dashboards that update, and a notes tab explaining every one so you can maintain it yourself.
What you get: A working spreadsheet, not a screenshot of one — with every formula documented in plain English.
- VLOOKUP, XLOOKUP, INDEX MATCH, ARRAYFORMULA, QUERY
- Live dashboards, KPI tiles and charts
- Pivot tables and summary reports
- Macros and Apps Script for the repetitive parts
- Sheets wired to an API so data refreshes itself

Check the work before you spend anything
Most freelancers ask you to trust a portfolio screenshot. Everything below is live,
public and running right now. Open it, break it, read the source.
Purffle Tools
The site you are on. 182 working utilities, one Python backend, one Astro
front end. Every tool page is one I built.
purffle.tools
Purffle AI
A live AI assistant with seven expert modes and streaming replies. If you want
a chatbot, go and use the one I already run.
purffleai.com ↗
Purffle Chartwright
A desktop app where the language model is structurally unable to invent a
number — a Python engine computes every figure first. This is the hard part of
building an AI product, and it is shipped.
purffle.com/purffle-chartwright ↗
The source code
Six public repositories, MIT licensed — desktop apps, trading bots and AI video
tools. Read the actual code I write.
github.com/Chamanrajragu ↗
Purffle Studios
Three shipped games, 39,000+ downloads across 75+ countries. Built solo in Unity —
proof I finish things.

Five sites, nine products, one developer. The full picture of what has been
shipped since 2020.

where you already hire.

How it works
- You describe the task in plain English. No spec document needed. "Every Monday I
download four reports and paste them into one sheet" is enough to start.
- I tell you honestly whether it is worth doing. Sometimes the answer is that a free
tool on this site already does it. I will say so.
- Fixed price and a delivery date, agreed before I start. No hourly billing, no
scope creep, no invoice that grows.
- I build it and test it on your real data. Not on a sample I made up — on yours.
- You get the working file and the source. Yours to keep, modify and re-run. No
licence, no subscription, no lock-in.

Straight answers
Who actually does the work?
I do. Chaman Raj R, one person in Chennai, India. There is no agency behind this and nothing is passed to a subcontractor. The person you message is the person writing the code.
Why should I trust someone with no reviews yet?
Fair question — I am new on Fiverr and I am not going to pretend otherwise. What I am not new at is shipping: this site and its 182 tools, a live AI assistant, three published games and six public repositories are all mine and all inspectable right now. Read the code on GitHub before you spend anything.
How do I know the work will be correct?
Because I only take jobs where I can check the result myself before I hand it over. I run your script on your real sample data, I open the spreadsheet and check the numbers, I talk to the chatbot. If something is wrong, I find it, not you.
What does it cost?
Fixed price, agreed in writing before I start — no hourly billing and no surprises. Current prices are on the Fiverr gig pages. Message me with what you need first and I will tell you honestly which package fits, or that it does not need one at all.
What if my job is not on this list?
Ask anyway. If it is something I can build and verify, I will say yes and quote it. If it is not, I will tell you straight rather than take the money and improvise.
Why go through Fiverr instead of paying you directly?
Fiverr holds the payment until you approve the delivery, which protects you rather than me. For a first job with someone you have never worked with, that is the right way round.
Tell me what you keep doing by hand.
Message me with the task before you order anything. If I cannot do it properly,
I will tell you — and that costs you nothing.
