The Goal: A Full-Stack App From Scratch
I wanted to build a complete web application from scratch to manage local events. The goal was ambitious: handle everything from user authentication and event listings to a secure booking and payment system.
All of this had to be done using only free services, as I had no budget.
The Human Challenge: A Solo Project
This project was originally intended for a team of four. When my teammates had to drop out, I was too invested to let the idea go.
This created a perfect storm of problems:
No Manpower: I was now a solo developer facing a 4-person workload.
No Time: My university exams were happening at the same time.
No Money: I had a strict zero-cost constraint.
I knew the risk-to-reward was low, but I couldn't let the opportunity to learn pass by. I worked late every night, often until 1 or 2 AM, to see how far I could push myself and the project.
The Tech Stack
To build this, I relied on a powerful, free, and open-source stack:
Backend: Python with the Django framework.
Database: SQLite (built into Django) for managing all event and user data.
Frontend: Standard HTML, CSS, and Bootstrap for responsive templates.
Core Technical Features (The "Proof of Work")
Custom User Authentication: I built a complete user system from scratch, handling everything from user signup (user_signup) to login (user_login) and profile management (profile).
Database Modeling: I designed the database schema to connect three critical models: Event, Booking, and Payment. This relational structure ensured that a single booking could be tracked from the moment of creation to its final payment confirmation.
Secure Payment & Ticketing: Because I couldn't use a paid service like Stripe, I had to build a "proof-of-concept" payment simulation.
A user books an event, creating a Booking and a Payment object with a status of "pending".
In the process_payment view, the system simulates a successful transaction (like "Cash on Delivery") and updates the status to "completed".
Once completed, the view generates a unique QR code for the booking and saves it as an image, serving as the user's "ticket" for the event.
From paymentapp/views.py - How I generated a unique "ticket"
... inside the process_payment function ...
if payment.payment_method == 'cod':
payment.payment_status = 'completed'
payment.save()
# Link the completed payment back to the booking
booking.payment = payment
booking.save()
# Generate the QR code as a ticket
qr_data = f"BookingID: {booking.id}, Event: {booking.event_name}, User: {booking.user.username}"
qr_img = qrcode.make(qr_data)
# ... code to save and store the QR code image ...
return redirect('payment_success', booking_id=booking.id)
Biggest Challenge: The Free Service Constraint
The zero-cost rule forced me to get creative.
My original plan included a "venue suggestion" feature using a paid location API. When that became impossible, I pivoted to OpenStreetMaps. Unfortunately, I discovered that its venue data for many states in India was too sparse to be useful.
This forced a second pivot: I changed the feature from an automated system to a manual-service system. The user inputs their "preferred location," and an admin is notified to find the best venues for them manually. This taught me a valuable lesson in product development: sometimes, a "concierge" solution (a human doing the work) is a necessary first step.
What I Learned
In the end, I was running out of time. I had to release the "fail-safe" version—a stable app with the core booking logic—instead of the more complex version with event tiers and add-ons.
This project was a crash course in working under pressure. It taught me more than any textbook could about:
Task Management: How to break down a massive project into solvable daily tasks.
Prioritization: How to identify the "must-have" features (like payment) and cut the "nice-to-have" features (like location suggestions) when a deadline is real.
Resilience: That I am capable of building a full-stack application entirely on my own, from the first database model to the final deployment.
I'm proud of what I built and I look forward to rebuilding it one day with all the features I originally dreamed of.
