Samples
This system is a comprehensive, secure, mobile-first ordering and management platform. It includes setting up hosting and security, developing a database and admin portal for managing inventory and pricing, and creating a customer-facing front-end with time slot logic. The system also features a real-time kitchen dashboard for order fulfillment and integrates secure payment processing with Stripe and automated communication.
This system is a secure, cloud-hosted vehicle inspection platform with a core database managing vehicles, staff, and inspection data. It features a staff-facing tablet app for optimized check-out/check-in, capturing mandatory images and tagging damage locations. Backend logic handles staff authentication, status changes, and comparison of inspection data, automatically alerting managers to critical discrepancies via email, which are then viewable on a secure web dashboard for reporting.
This system is an AI-powered document processing tool designed for staff use. It securely hosts the application and handles staff authentication. Core functionality includes a secure web interface for uploading documents, which are then processed using OCR for text extraction and immediately deleted. The extracted text is sent to an integrated Large Language Model for summarization and key clause extraction, with logic for handling long documents. The results are displayed in a web UI for review and can be exported, with an audit log for monitoring usage.
This system is a real-time queue and staff management solution built around a database and core socket server. It manages staff actions—like clock-in, breaks, and sign-offs—via a stylist tablet interface. Concurrently, it handles customer entry and utilizes this data to drive an integrated LED display, powered by a Raspberry Pi, which scrolls queue information and predictions. The project concludes with necessary testing and staff training.
This system is an inventory management solution featuring secure hosting, a PostgreSQL database for core item and stock data, and staff authentication. Its primary functionality includes a mobile-optimized interface for warehouse stock updates, an admin control for setting minimum stock thresholds, and an automated alert system. The alert system uses comparison logic with throttling to prevent repeat notifications, integrating with SMS and email gateways for multi-channel communication based on user preferences.
This system is a real-time room management application designed for hospitality staff. It features secure hosting, a real-time database with WebSockets for instant status updates, and a core logic that manages the room status flow from occupied to ready. The system includes separate web interfaces for reception and housekeeping, a public lobby display, and logic to prevent integrity errors in status transitions.
Start
The first step is understanding your vision. Please follow this simple structure:
1. Capture Your Dream
Start with the why and the what. What will this software allow your business to do that it can’t do today?
2. Break it Down
Divide your vision into specific features or topics. Use bullet points to describe what each part needs to achieve. You can also look at the Samples section examples for guidance.
Example:
- Topic: Online Booking
- Must check staff availability in real-time.
- Accept £10 deposits via Stripe.
- Send SMS reminders 1 hour before appointments.
3. Send the Details
Email me your breakdown, or send it via WhatsApp if that’s easier.
4. Free Technical Review & Estimation
I will research technical solutions for your needs (free of charge) and provide a detailed time estimate for each feature.
5. Scope Agreement
We’ll review the plan together. If you’d like to dive deeper, we can meet at your office, a local cafe, or jump on a video call.
6. Project Commencement
Work begins once the plan is agreed upon and a 50% deposit is received. I’ll provide regular progress updates as I build.
7. Agile Pivots
Software is dynamic! If you want to refine the direction as you see the work come to life, that’s welcome. Minor adjustments are natural; major shifts in scope will be discussed and priced fairly before proceeding.
8. Handover & Ownership
Once the work is complete, I can assist with installation and provide 1–2 hours of hands-on training. Upon final payment, I’ll transfer all source code, assets, and intellectual property to you. If you paid for it, you own it.
