Real systems built to solve real business problems.

Context

The client had strong organic traffic but lacked a structured system to convert visitors into paying customers through a reliable purchase flow.

Problem

Checkout friction, limited payment support, and the absence of a centralized order system created missed conversion opportunities and unnecessary operational work.

Approach

Harmion redesigned the purchase journey, reduced unnecessary steps, introduced multiple payment gateways, and built a modular backend so the platform could grow without repeated structural changes.

What we built

Shopping cart, streamlined checkout, Stripe and PayPal integration, order processing workflows, admin panel, and an SEO-friendly structure.

Technologies

PHP backend, MySQL database, Stripe and PayPal APIs, REST-style integrations, HTML, CSS, and JavaScript.

Outcome

A smoother checkout experience, stronger conversion potential, and a scalable system capable of supporting growing traffic and transactions.

Context

The client offered multiple camp programs but lacked a unified system for discovery, filtering, and booking across locations.

Problem

Users struggled to find relevant camps, and the booking flow was fragmented, making both discovery and operations harder than they needed to be.

Approach

Harmion designed a discovery-first experience with search, filters, and maps, then streamlined the booking process while adding backend tools that made administration easier.

What we built

Search and filtering system, Maps API integration, user accounts, cart and checkout flow, Authorize.Net integration, and an admin control panel.

Technologies

PHP backend, MySQL, Maps API, Authorize.Net, JavaScript-based UI, and a responsive frontend.

Outcome

Improved camp discovery, a smoother booking experience, and a centralized platform for managing users and operations more efficiently.

Context

An established online course platform running on legacy PHP needed modernization without disrupting active users or business-critical flows.

Problem

Performance bottlenecks, difficult maintenance, and the risk of breaking existing checkout and course delivery workflows made change increasingly risky.

Approach

Harmion used an incremental refactoring strategy, improving performance and stability step by step while preserving existing functionality and minimizing operational risk.

What we improved

Refactored critical code paths, optimized queries, improved response times, and stabilized core user flows including checkout and course access.

Technologies

Legacy PHP modernization, MySQL optimization, existing shopping cart integration, and practical performance tuning techniques.

Outcome

Improved performance, stronger reliability, and an extended platform lifespan without the cost and disruption of a full rewrite.
