Project details
I will investigate complex production issues that may involve both the application and infrastructure layers.
This service is suitable when the problem cannot be clearly attributed to WordPress, PHP, the server, database, CDN, API, or frontend.
I can investigate areas including:
Nginx;
PHP-FPM;
PHP applications;
WordPress;
REST APIs;
CORS;
MySQL/MariaDB;
PostgreSQL;
Cloudflare;
SSL;
DNS;
cron;
PM2;
DigitalOcean;
S3-compatible storage.
My approach is based on tracing the complete application flow and identifying the actual failure point before making changes.
You will receive either a verified fix or a documented root cause and technical remediation plan.

About Viktoriya
Senior WordPress & PHP Engineer | LMS, APIs, OpenCart, Troubleshooting
Dnipro, Ukraine - 11:01 pm local time
I am an Senior WordPress & PHP Engineer | LMS, APIs, OpenCart, Troubleshooting.
I help businesses fix, extend and stabilize complex WordPress, LMS and e-commerce platforms.
I have 12+ years of hands-on experience with WordPress development and production support, including custom plugins, LMS platforms, API integrations, OpenCart systems, databases and server-side troubleshooting.
My strongest area is solving problems that are difficult to diagnose because they involve multiple layers of the system — WordPress, plugins, PHP, JavaScript, database, CDN, server configuration or external APIs.
I work with both existing production systems and new custom development.
WordPress Development
I can help with:
custom WordPress plugins
custom functionality
PHP development
WordPress REST API
AJAX
custom admin interfaces
ACF
legacy WordPress projects
database troubleshooting
plugin conflicts
performance and stability issues
LearnDash / BuddyBoss / LMS
I have extensive practical experience with complex LMS platforms using:
LearnDash
BuddyBoss
GamiPress
H5P
ACF
custom dashboards
learning progress tracking
quizzes and assessments
reporting
certificates
external learning trackers
I can diagnose and fix issues involving:
LearnDash quizzes
quiz completion
autosave/resume
progress synchronization
BuddyBoss groups
LMS performance
custom reporting
student dashboards
third-party integrations
I also design custom LMS components when standard plugins are no longer sufficient.
OpenCart & E-commerce
I work with OpenCart 2.x, 3.x and 4.x.
Typical tasks include:
custom OpenCart modules
custom themes
product pages
catalog pages
product filters
admin functionality
attributes
product options
automated price updates
inventory synchronization
import/export
API integrations
API & Integration Development
I build and troubleshoot integrations involving:
REST APIs
webhooks
JSON
PHP
JavaScript
Google Apps Script
WordPress APIs
third-party platforms
data synchronization
automated imports
Server & Production Troubleshooting
When an application issue is not actually caused by the application itself, I can investigate the infrastructure layer as well.
Experience includes:
Linux
Nginx
PHP-FPM
MySQL / MariaDB
PostgreSQL
Cloudflare
SSL
DNS
CORS
cron
PM2
DigitalOcean
S3-compatible storage
What You Can Hire Me For
WordPress Technical Audit
I analyze a WordPress installation, plugins, database, PHP environment, performance, conflicts and architecture and provide a clear remediation plan.
LearnDash / BuddyBoss Troubleshooting
I investigate complex LMS problems involving quizzes, progress, groups, dashboards, reporting and integrations.
Custom WordPress Plugin Development
I build custom business functionality that should not depend on theme hacks or dozens of third-party plugins.
API Integration
I connect WordPress or e-commerce platforms with external services, trackers, CRMs and custom APIs.
OpenCart Development
Custom frontend, backend, catalog, product, import and administration functionality.
Production Incident Investigation
For difficult bugs where the cause may be in JavaScript, PHP, WordPress, SQL, Nginx, Cloudflare or an external API.
My Approach
For complex tasks, I normally work through:
Reproduce → Diagnose → Identify Root Cause → Implement → Verify → Document
I avoid replacing one problem with another temporary workaround.
For production systems, I pay particular attention to:
backups
rollback
backward compatibility
data integrity
logging
safe deployments
