Full-Stack Developer | Laravel โข PHP โข React โข Node.js | CRM, Web Apps & Custom Development
I build, fix, and improve web applications โ custom CRM systems, business portals, SaaS platforms, admin dashboards, and e-commerce backends.
Full-stack PHP developer with 12+ years of experience. Laravel on the backend, React or Inertia.js on the front, MySQL and PostgreSQL underneath.
Most of my work falls into two categories: building something from scratch that fits how a business actually operates, or coming into an existing application and making it work properly โ debugging broken functionality, improving performance, restructuring code that has become unmaintainable, and adding features to systems a previous developer left unfinished.
WHAT I BUILD
Custom CRM & Business Application Development
* Custom CRM systems built around real business workflows โ not a generic off-the-shelf template
* Recruitment and candidate tracking portals
* Client and project management systems
* Quote-to-invoice and job management flows
* Multi-role admin panels with proper role-based access control and permission management
* Healthcare, legal, and professional services portals
* Internal tools and business dashboards
Full-Stack Web Application Development
* Laravel and PHP backends โ REST API development, Eloquent ORM, queue jobs, scheduled tasks, background processing, authentication, and business logic
* React.js frontends with Inertia.js or standalone SPA builds
* Next.js for performance-critical or SSR applications
* Node.js and Express APIs
* MySQL and PostgreSQL โ schema design, query optimisation, database architecture
* Third-party API integrations โ ERP, LMS, accounting platforms, HR systems, and external services
WooCommerce & WordPress Custom Development
* WooCommerce beyond what plugins can handle โ custom pricing logic, checkout flows, B2B and wholesale systems, POS integration, WooCommerce REST API
* Custom WordPress plugin development
* Site migrations, performance optimisation, Core Web Vitals improvement, security hardening
Bug Fixing, Performance & Application Improvement
* Debugging broken or unstable web applications
* Performance recovery โ slow queries, unoptimised code, server misconfiguration
* Inherited codebases that need restructuring before new features can be added safely
* Failed or unreliable API integrations
* Security issues and access control gaps
* Laravel upgrades and PHP version migrations
WHAT I HAVE SHIPPED
* Multi-module CRM for a recruitment agency โ candidate pipeline, placement tracking, document management, role-based access
* Laravel healthcare portal with form-to-assessment flows, Google Sheets sync, and admin settings panel
* Laravel e-commerce platform with complex product configuration and custom pricing logic
* WooCommerce B2B and B2C store with POS integration โ admin ordering on behalf of customers
* Node.js SaaS application with third-party file storage, email, AI, and billing integration, deployed to production
HOW I WORK
Before writing any code I take time to understand what the application actually needs โ and I will tell you early if there is a simpler way to get there.
My approach is structured and transparent. You will always know what I am building, why, and what comes next.
Most of my clients are based in Ireland and the UK โ I am used to working async, communicating clearly in writing, and taking full technical ownership without needing hand-holding.

When a business operation runs on people instead of systems, or when an AI layer drifts because it's answering from generic knowledge instead of the company's own data, or when three platforms are supposed to sync and none of them do, that's the kind of system I built.
I build AI systems using Laravel and Python as the foundation. RAG pipelines, multi-agent workflows, LLM integrations, production backends with deep third-party integrations, compliance-grade where the domain demands it.
โฆ Work that reflects this:
ยป Built Therapy adherence workflow engine for a home medical equipment provider, 40+ states, millions of patients. Medicare only reimburses CPAP if documented compliance is proven within a fixed window. Built a system that monitors 12 trigger types per patient, low usage, mask leak, high AHI, missed downloads surfaces them by proximity to their reimbursement deadline, not just trigger volume.
Every outreach outcome and compliance date writes back to the ERP in the same session. Integrated with device telemetry. Built each trigger type independently, a generic handler for all 12 would have made compliance auditing unmanageable at that scale.
ยป Designed Patient intake pipeline for the same company. Agents were triaging faxes manually, re-keying data into the ERP, entering insurance tiers separately. Replaced the whole thing, document triage, patient matching, primary/secondary/tertiary insurance write-back, sales order creation, document attachment, all through the ERP's services layer in one session. ~70% reduction in intake processing time.
ยป Shipped Virtual-first outpatient care platform for a NASDAQ-listed healthcare clinic. Two treatment journeys: overactive bladder and menopause. Symptom checking, daily tracking tools, behaviour recording, compliance reports auto-distributed to ordering physicians. Integrated Auth0, Redox, SurveyJS, Kommunicate, Convo, Twilio, Logrocket. Compliance surface: HIPAA, HITRUST, OWASP, SOC2, CURES.
ยป RAG-based AI operations assistant for a 30-year insurance consultancy. Hard requirement: cannot answer outside its approved document scope. Each agency gets its own assistant trained only on their SOPs, no generic drift. Survey engine auto-generates customised audit guidelines per agency from submitted responses, versioned, admin-approved, downloadable as compliance PDFs. Audit handling time down 45%, staff training ramp-up cut by ~50%.
ยป Loan origination flow for a non-bank lender, lead to settlement, with a live three-way sync between the custom platform, HubSpot, and the origination system. Any status change propagates to all three without manual reconciliation.
ยป AI email triage system on N8N, classifies support, sales, and job applications, generates branch-specific replies using separate prompt templates per category, logs to Airtable, posts Slack summaries. Architecture built for a multi-agent upgrade, classifier, responder, and auditor agents running independently with shared memory.
ยป E-commerce: AI fraud detection for bulk orders, automated product description and meta ad generation, AI image and media creation, OpenAI, Gemini, and Claude running in production on a high-volume DTC platform.
