About this service

Summary

I build custom web applications and robust APIs, designed specifically to solve your unique business challenges. I'm not just a coder, but your technical partner, focusing on scalable and secure architecture to support your long-term business goals.

Process

My development process is designed to be transparent, collaborative, and focused on delivering a high-quality product that meets your business objectives. Here are the steps we'll take together:

Step 1: Discovery & Strategic Alignment

We begin with an in-depth workshop to understand your business goals, target audience, and key success metrics. This isn't just about listing features; it's about aligning on the "why" behind the project. The outcome is a clear project brief and a shared vision for the final product, ensuring we are building the right solution from day one.

Step 2: Architecture, Planning & Prototyping

With a clear vision, I design the system architecture, database schema, and map out the core user flows. This is the blueprinting phase where we create a solid technical foundation for your application. Depending on the project, we may also create wireframes or a clickable prototype to validate the user experience before diving into development.

Step 3: Agile Development & Regular Updates

This is where your vision comes to life. I develop the application in focused cycles, or "sprints," tackling features in order of priority. You will receive regular progress updates and demos at the end of each cycle, ensuring you are always in the loop and have opportunities to provide feedback throughout the development phase.

Step 4: Rigorous Testing & Quality Assurance

Quality is paramount. Before deployment, the application undergoes rigorous testing, including unit tests, integration tests, and security checks. I ensure the code is optimized for performance and that all features function exactly as intended, providing a stable, secure, and reliable end product.

Step 5: Deployment, Launch & Handover

I handle the entire deployment process, from configuring the server environment to pushing your application live. Once launched, I conduct a formal handover session, providing you with all the necessary documentation, full source code access, and administrator credentials. I'll also provide a brief training to ensure you're comfortable managing your new application.

Step 6: Post-Launch Support

My commitment doesn't end at launch. Your project includes a 14-day post-launch support window to address any critical bugs or unforeseen issues that may arise. My goal is to ensure a smooth and successful transition for you and your users.

FAQs

What does our work process look like after I order this service?
Our process is structured to ensure transparency and the best results. We start with an in-depth discovery session to understand your business goals, followed by architecture and feature planning. Next are the core development sprints, quality assurance (QA) testing, and finally, deployment to your server and a project handover session.
What factors influence the final project price?
The starting price is a baseline. The final price is determined by several key factors: the total complexity of the features, the number and intricacy of third-party API integrations, custom UI/UX design requirements, and any accelerated timeline requests. After our discovery session, you'll receive a detailed proposal with a transparent cost breakdown and no hidden fees.
What technology stack do you use?
I specialize in the Laravel (PHP) ecosystem for the backend, known for its security, scalability, and high performance. For the frontend, I'm proficient with Vue.js, Livewire, and Tailwind CSS to create modern and responsive interfaces. However, I always choose the technology stack that best suits your project's specific needs.
Who owns the rights to the source code after the project is complete?
You do. Upon final payment, full intellectual property rights for the source code developed specifically for this project are transferred entirely to you. I will deliver it via your private Git repository (e.g., GitHub or GitLab).
What if I want to add or change a feature midway through the project?
Of course. Changes are a natural part of custom projects. For any feature requests outside the original scope, we'll create a "change request" document. This will detail the additional work, cost estimate, and any adjustments to the timeline, ensuring everything remains transparent for both of us.
Does this service include UI/UX design?
This service focuses on the technical development (backend and frontend). Ideally, you will provide the completed UI/UX designs (e.g., Figma or Adobe XD files). However, if you don't have a designer, I can connect you with talented UI/UX professionals from my network.
Is there technical support after the application is launched?
Yes, this service includes a 14-day complimentary support window for bug fixes post-launch. For long-term support, server maintenance, or ongoing feature development, I offer monthly maintenance retainer packages that we can discuss based on your needs.

What's included

Full Source Code Access
You will receive the complete, clean, well-structured, and commented source code for the application. The code becomes your full intellectual property, delivered via a private Git repository (GitHub/GitLab) for easy version control and future development.
Live & Deployed Application
Your application will not only be developed but also fully deployed and activated on your chosen server environment (e.g., AWS, DigitalOcean, or a private server). It will be live and ready for access by your internal team or the public.
Comprehensive API Documentation
I will provide interactive and user-friendly REST API documentation (using standard formats like a Postman Collection or Swagger/OpenAPI). This makes it incredibly easy for your team or other developers to integrate with the system in the future.
Database Schema & Diagram
You will get a visual diagram and the schema file of the application's database structure. This is crucial for data understanding, reporting, and planning future features, providing a clear blueprint of your data assets.
Deployment & Environment Guide
A technical document outlining the step-by-step process for setting up the project in a new environment and all necessary configuration variables. This ensures your team can manage and redeploy the application independently.
User Guide & Admin Handover
A concise guide (in PDF or a short video format) explaining how to use the main features of the application from an admin or user perspective. This includes the secure handover of the primary administrator account credentials.
Post-Launch Support Window
To ensure a smooth transition, I provide a 14-day complimentary support window after the official launch. This covers fixing any bugs or critical issues related to the original scope of work. New feature requests are not included.
