How We Build Custom Web Applications: From Payment Systems to Scalable Platforms

At 2Way.ro, we transform business needs into robust, efficient, and scalable digital systems.

In a world where no two businesses operate exactly the same, off-the-shelf software often falls short. That’s why at 2Way.ro, we specialize in building custom web applications tailored to each client’s goals. In this article, we walk you through a real-world approach to how we architect, develop, and launch full-featured web platforms with advanced functionality such as:

  • Online payment integration (Stripe, PayPal, crypto)

  • Custom dashboards & CRM systems

  • Complex forms & data collection workflows

  • Real-time reporting & data analysis

  • Shopify and WooCommerce ecommerce integrations

Understanding the Business Case

Before writing a single line of code, we sit down with our clients to understand the purpose and outcome of their platform. Whether they need a subscription service, a multi-vendor ecommerce shop, or a tool for managing internal processes, we ensure the digital product aligns with real-world goals.

Tech Stack We Use

Our core stack includes:

  • Frontend: HTML, CSS, JavaScript (Vanilla JS or frameworks like Vue.js)

  • Backend: PHP (Laravel or custom MVC), MySQL

  • Cloud Infrastructure: DigitalOcean, AWS, Google Cloud

  • Version Control & CI/CD: Git, GitHub Actions

When required, we also incorporate third-party services like Firebase, Mailchimp, Twilio, or Telegram bots.

Payment Systems: Stripe, PayPal & Crypto

We frequently integrate payment APIs to accept:

  • One-time or recurring card payments via Stripe

  • PayPal transactions (including multi-currency)

  • Crypto payments (Bitcoin, Ethereum) via platforms like Coinbase Commerce or NOWPayments

Security, reliability, and seamless user flow are our top priorities. We validate inputs, handle webhooks, and follow PCI compliance best practices.

Advanced Forms and Data Flow

From multi-step forms for booking appointments to quote generators and surveys, we craft interfaces that are both user-friendly and data-rich. Data is stored securely in MySQL, sanitized and structured for future use in dashboards or reports.

Building for Scale

Every custom application is built with growth in mind. We:

  • Use cloud servers with automatic scaling

  • Apply caching techniques and database indexing

  • Build modular code that supports plugin-like extensions

Ecommerce Integration: Shopify & WooCommerce

For clients who already use ecommerce platforms like Shopify or WooCommerce, we offer custom integrations. Whether it's syncing data with external systems, implementing custom checkouts, or adding upsell flows, we make the tools work for you, not the other way around.

Real-World Case Study (Coming Soon)

In future blog entries, we’ll dive deeper into specific projects: how we built a crypto donation platform, a B2B marketplace dashboard, or a hybrid CRM with real-time analytics.
