My Story

I’m a backend-focused web developer delivering seamless WordPress, Shopify, Laravel integrations. I work primarily with PHP-based systems, legacy codebases, and custom e-commerce APIs.

Most of my work involves stepping into existing codebases, fixing broken flows, cleaning up legacy logic, stabilizing authentication systems, and extending applications without risky rewrites. I’ve built REST APIs for mobile apps, implemented role-based access control, handled session security, and integrated third-party services across real production environments.

I regularly work under practical constraints, shared hosting, legacy databases, rate-limited APIs, and growing systems that need to keep running while being improved.

I don’t position myself as a large agency or a high-scale infrastructure specialist. My value is in understanding how systems actually behave, diagnosing backend issues, and delivering fixes like complex WordPress Shopify Laravel integrations—that are maintainable, realistic, and aligned with your business goals.

Backend Development & Fixes

I build and fix backend functionality in PHP systems, focusing on features that support real product needs. This includes authentication flows, role-based access, APIs for web or mobile apps, form and survey logic, file uploads, and backend processes triggered from frontend interactions.

This is suited for applications with broken backend behavior, incomplete features, or systems that need new functionality added without disrupting existing users.

Performance & Stability Improvements

I help identify and fix practical performance and stability issues within existing systems. This includes cleaning up inefficient queries, reducing unnecessary API calls, improving backend and frontend coordination, and optimizing sites running under shared hosting constraints.

This is appropriate when a site feels slow or unreliable under normal usage and needs targeted improvements without infrastructure changes.

WordPress & Shopify Backend Support

I handle backend-focused work for WordPress and Shopify systems, including plugin conflicts, custom logic, API integrations, and JavaScript-to-backend flows that standard themes and plugins do not cover.

This is useful when a site is technically unstable, behaving inconsistently, or needs backend customization beyond basic configuration.

Integrations & Data Flows

I build and maintain integrations between systems, including mobile apps and backend APIs, third-party REST and GraphQL services, Shopify integrations, CSV import workflows, and event tracking setups.

This is a good fit when a system needs to communicate reliably with external services or automate data movement without manual intervention.
