PHP Developer · Laravel · Symfony · Ireland
PHP Full-Stack & Backend Developer in Ireland.
I build and maintain PHP business applications, Laravel and Symfony backends, REST APIs, MySQL/MariaDB systems, reporting tools and integrations — with a practical focus on reliability, maintainability and real business operations.

Focus
Software built around real business processes.
Existing systems
Understanding mature codebases, fixing production issues and improving them without unnecessary rewrites.
Data, reports & automation
Operational reporting, Excel exports, APIs, scheduled processes and tools that reduce repetitive work.
Where I fit best
Projects where software is part of the daily operation.
I am most useful when the application has real users, real data and business rules that need to keep working while the product evolves.
01 / EXISTING PHP SYSTEMS
Maintain and evolve mature applications
Work safely inside existing architecture, preserve business-critical behaviour and improve the code incrementally.
02 / INTERNAL PLATFORMS
Operational and management systems
Dashboards, workshop operations, stock, sales, permissions, parts, customer data and internal workflows.
03 / INTEGRATIONS
APIs and data flows
Connect systems, process external data and build reliable interfaces between applications.
04 / AUTOMATION
Remove repetitive operational work
Scheduled jobs, imports, exports, scripts, browser tooling and practical automation around existing processes.
Services
How I can contribute.
From a specific backend feature to long-term development of an internal business platform.
PHP application development
Backend features, domain rules, forms, authentication, permissions and production workflows.
REST APIs & integrations
Endpoints, external services, JSON/XML data flows and integration logic between systems.
Database & reporting
SQL, operational reports, KPIs, large exports, Excel generation and practical data analysis.
Legacy system improvement
Debug existing code, reduce risk and modernize incrementally instead of rewriting everything.
Automation & internal tooling
Scripts, cron-style tasks, browser extensions and tools that simplify repetitive operational work.
Deployment & infrastructure support
VPS environments, Linux, Windows Server, IIS, Plesk, Docker and practical deployment troubleshooting.
How I work
Understand first. Change carefully. Improve continuously.
I prefer practical improvements that respect the current system, its users and the business behind it.
01
Understand the real requirement
Start with the business process, current behaviour, data and operational constraints.
02
Trace the system impact
Identify affected code, database structures, permissions, integrations and edge cases before changing production logic.
03
Implement the smallest reliable change
Avoid unnecessary rewrites and keep changes understandable, testable and easy to support.
04
Verify with real operational scenarios
Check the result against the workflow users actually follow — not only the happy path.
