I am a solo developer in Chennai, India, and I build and ship software on my own: Python automation and web scraping, custom AI chatbots that answer from your documents instead of inventing answers, Electron desktop apps for Windows, macOS and Linux, Flask dashboards and trading bots, and Unity games. All of it runs under one brand — Purffle — and every project below is live, free to use, and open to inspection before you decide whether I am any good.

96,000+ downloads across the network · 6 open-source repositories · 180+ free web tools · 3 published games in 75+ countries · everything designed, coded and shipped by one person.

Everything here is free. No paid tiers, no accounts, no telemetry. Five of the six repositories are MIT licensed; PurffleGrab v10 and later ship under their own binary licence (everything up to 9.0.0 stays MIT), and Purffle Chartwright is free but closed-source for now.

I build this kind of thing for other people too — fixed price, agreed before I start.

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. If something is broken, I find out — not you. It's also why I turn work down: if I can't verify it, I'll say so instead of taking the money and hoping.

The proof is this page. Everything below is public, running, and yours to read before you spend anything — six repositories, a live AI assistant you can talk to right now, a desktop app whose language model is structurally unable to invent a number, 180+ free web tools and three shipped games.

Ask a chatbot where support is and it will tell you — confidently, and from nowhere. It picks a satisfying round number, sounds certain, and never saw a bar. That is not a prompt you can fix; it is what a text model does when asked about numbers it cannot see.

Chartwright removes the opportunity. A deterministic Python engine computes the swing structure, the level clusters, the indicators, the volatility and the position arithmetic first — in about two tenths of a second — and only then is a language model handed those figures and asked to explain them. It has no access to raw bars, so it cannot state a price no tool returned, and every figure in an answer expands into the function that produced it.

• Every price computed, never generated — the model sees tool results, never the price series
• Explain mode — one plain-English sentence under every reading, generated from the value it sits under, so you do not need to already know what ADX is. Switch it off and the panel goes dense; the numbers are identical either way
• Levels ranked by evidence — touch count, recency, and how cleanly price respected each one
• A backtester that does not flatter you — next-bar-open fills, costs charged both sides, a bar holding both stop and target counted as a loss, and 10 strategies each labelled published and replicated, published then decayed, folklore or unknown
• Journal scored in R, the same unit the backtester reports in, so your execution and the system's history are directly comparable
• Runs on your machine — with a local model the entire loop works with no network at all
• Not a predictor, and never connected to a broker. It cannot place an order and it never will

Every price is computed. None are invented.

The published benchmark is in the box. Across three instruments and two questions, small local models asked without chart data gave 34 prices out of 72 that sat outside everything the instrument had traded. Handed this engine's output first: 0 out of 38. The harness ships as scripts/benchmark.py so you can re-run it.

This is the chatbot gig, running in public. Open it and start typing — there is no account, no key and no paywall between you and the model. Seven modes (general, code, creative writing, analysis, translation, maths and tutoring) each carry their own system prompt and interface, and the whole thing is a static front end talking to an inference API, which is exactly the shape most "chatbot on my website" projects need.

Llama 3.3 · Groq · 7 modes · No account · No tracking

• Nothing to sign up for — no email wall, no trial, no credit card
• Seven specialised modes, not one prompt with a different label
• Markdown, code blocks and syntax highlighting in replies
• Conversation history stays in your browser — it is not collected

If you want one of these trained on your own documents, that is the gig — same build, pointed at your content, with the source code handed over at the end.

Never hit the Claude usage limit again. The moment one account reaches its 5-hour cap, Claude Multi carries the full conversation to a free account and re-issues the interrupted instruction — your task keeps running instead of dying halfway.
