Build "Split the Bill": An app that lets a group split a shared expense
(dinner, trip, event) and collect payment from each person individually
through Stripe, instead of one person fronting the money and chasing
everyone else down afterward. The organizer enters the total bill amount,
the number of people, and their names — the app calculates each person's
exact share and generates a unique payment link for each of them. Each
person opens their own link and pays their share directly via Stripe
Checkout. The app tracks who has paid in real time and shows a live
progress bar ("X of Y paid"). Past splits are saved locally so the
organizer can review previous bills.
Requirements:

Build "GitQuest": An Interactive Gamified GitHub Learning Platform ("Duolingo for GitHub").
GitQuest turns learning Git and GitHub from intimidating documentation into a playful, hands-on, quest-based game.
Instead of watching tutorials, learners:

Validate a startup idea before writing code. Next.js 15 (App Router), TypeScript, Tailwind, OpenAI, and Stripe Checkout.
Stop building bad startups.
Founders spend months — sometimes a year — shipping a product nobody wants. The expensive mistake is not writing bad code. It is building the wrong company.
FounderScope is an AI analyst that stress-tests the idea first: market, competition, revenue, risk, and a 90-day MVP plan. Then it tells you whether to build or walk away.
| Feature | What you get |
|---|---|
| Market analysis | TAM, SAM, SOM and demand signals |
| Competition | Incumbents, substitutes, and whitespace |
| Revenue potential | Pricing, conversion, and three-year scenarios |
| Risk assessment | Regulatory, technical, and go-to-market risk |
| MVP roadmap | A sequenced 90-day plan |
| Investor pitch | Problem, wedge, model, and ask (Pro) |
| PDF export | Print-ready report and deck (Pro) |
| History | Reopen past analyses in this browser |
| Plan | Price | Includes |
|---|---|---|
| Free | $0 | 1 analysis, full verdict, saved locally |
| Pro | $5 / month | Unlimited analyses, investor pitch generator, PDF export |
| Checkout is Stripe Checkout (subscription). The success page verifies the session with Stripe before unlocking Pro. Query parameters are never trusted on their own. |

Mim is a live AI receptionist for Shahin Air Care, a one-stop AC service in Mirpur, Dhaka. A judge opens a browser “phone,” talks to Mim in English, gets a rate-card quote, receives an in-app SMS with a payment link, pays in a Stripe-style sandbox (no real money), and sees the owner dashboard update in real time.
This is a real conversation + booking + test payment demo. In production Mim would sit on a real shop phone number (Twilio Voice + SMS). Twilio is not free (so we simulates it in-browser phone instead of phone number calling)
Shahin owns a small AC shop. When he is on a job, the shop phone rings and he loses the booking. Mim, our smart ai receptionist answers calls, she understands the problem, checks if the area is served, quotes only from the rate card, holds a slot, and collects an advance so the slot is real.
Nusrat is the caller. She lives in Dhanmondi. Her AC is not cooling. She wants general servicing, a time tomorrow, and she is willing to pay an advance on her phone.
Judges play Nusrat on the call page and Shahin on the dashboard. They can haggle, refuse the link, or invent an emergency ,Mim will stay in character.
| Who | Want | So that |
|---|---|---|
| Nusrat (caller) | Speak or type in English and get a clear quote and slot( i tried bangla but free models are horrible in bengali) | She can book without waiting for Shahin |
| Nusrat | Pay a small advance on her phone | The technician actually comes |
| Shahin (owner) | See live calls, revenue, transcript, and a owner SMS | He knows what happened while he was out |
| Shahin | Reset the demo | The next judge starts clean |
| Judge | Use dummy login and a test card | They can try the full loop with no real account or money |
Slots are only held for 10 minutes until the advance is paid.
| Service | Price | Advance |
|---|---|---|
| AC general servicing | ৳800 | ৳500 |
| AC deep cleaning | ৳1,500 | ৳500 |
| Gas refill (after inspection) | ৳3,000 | ৳1,000 |
| New installation | Site visit only | — |
Areas served: Mirpur, Dhanmondi, Mohammadpur, Uttara, Bashundhara.
Out of area (polite no): Narayanganj, Gazipur, Savar, Chittagong, etc.
| Layer | Tool | Why |
|---|---|---|
| App server | Python FastAPI + WebSockets | Live call + dashboard, not a static site |
| UI | React + Vite | Call page, owner dashboard, checkout |
| Database | SQLite | Calls, bookings, payments, transcripts |
| Speech in (STT) | Groq Whisper (whisper-large-v3-turbo, English) |
Free, fast transcription |
| Brain | Google Gemini 3.6 Flash (AI Studio, free) | Natural English receptionist |
| Brain fallback | Groq qwen/qwen3.6-27b |
If Gemini is down |
| Speech out (TTS) | Microsoft Edge TTS en-US-JennyNeural |
Natural English voice, no paid TTS key |
| Checkout UI | Stripe-style sandbox on our server | BD cannot open a live Stripe account; look and flow match Checkout |
| Confirm pay | Test card 4242…4242 → backend PIN 1234 |
No Stripe charge, no bKash |
| HTTPS / mic | Cloudflare quick tunnel | Phones need HTTPS for the microphone |
| Host | Oracle Always Free Ubuntu ARM VM | Long-running Python + WebSockets |
Not used (and why): live Twilio Voice/SMS (numbers and minutes are paid), live Stripe (accounts not available from Bangladesh), Vercel / Hugging Face free hosting (no 24/7 WebSocket Python process).

| OS | Ubuntu 24.04 ARM (VM.Standard.A1.Flex) |

Use two tabs or two devices: phone = caller, laptop = owner. Allow the microphone when asked.

| “I won't pay on the link, cash when the tech comes.” | Soft-book. No argument. |
| “There's a burning smell / sparking / a baby can't sleep in this heat.” | Treat as emergency. Owner is notified on the dashboard. |
| “I'm in Narayanganj.” | Politely decline. No booking. |
| “Deep cleaning — what's the rate?” | ৳1,500, advance ৳500. |

Build "SOC Copilot": an intelligent Security Operations Center dashboard for analyzing and triaging security incidents.
SOC Copilot provides a security analyst-focused interface for investigating suspicious activity. Analysts can select simulated attack scenarios, review realistic security events and logs, run an automated triage process, and receive a structured assessment containing severity, confidence, MITRE ATT&CK mapping, and recommended response actions.
The application is designed as a lightweight SOC demonstration that allows judges to experience the complete incident-triage workflow without requiring access to a live SIEM or production infrastructure.
