Full-Stack Developer | Laravel • PHP • React • Node.js | CRM, Web Apps & Custom Development I build, fix, and improve web applications — 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 — 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 — 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 — 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 — schema design, query optimisation, database architecture * Third-party API integrations — ERP, LMS, accounting platforms, HR systems, and external services WooCommerce & WordPress Custom Development * WooCommerce beyond what plugins can handle — 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 — 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 — 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 — 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 — 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 — I am used to working async, communicating clearly in writing, and taking full technical ownership without needing hand-holding.

What does a Responsys Development specialist do?

A Responsys Development specialist builds and integrates Oracle Responsys marketing programs, messages, data imports, and automation workflows using Responsys developer and API capabilities. This role focuses on the technical configuration of campaign logic rather than just creative design. The specialist connects external data sources to the platform and ensures messages render correctly for each recipient.

  • Develops Responsys campaigns and program workflows to coordinate multi-step marketing execution across channels. This involves creating visual workflow builders with decision and routing logic based on tracking variables and data switches. The specialist maps out complex customer journeys that trigger specific actions based on user behavior or profile attributes.
  • Implements integrations via Responsys REST and SOAP APIs for managing data, content, and campaign-related resources. This work automates the creation and updates of campaign schedules, events, lists, and content library assets. The specialist writes code to connect external systems with Responsys features, ensuring seamless data flow without manual intervention.
  • Configures and automates audience and data import jobs, including profile lists, extensions, and supplemental data. This task requires setting up field mappings and defining schedule parameters for regular data synchronization. The specialist ensures that incoming data aligns with existing database structures to maintain list hygiene and accuracy.
  • Designs and manages message and email content layouts using Responsys message and template tools. This includes building HTML and text assets within the Message Designer and Visual Template Designer. The specialist applies reusable templates from the Content Library to maintain brand consistency across all communications.
  • Supports personalization and dynamic content rules using Responsys campaign and message configuration settings. This work ensures messages render different content blocks based on specific recipient or profile data points. The specialist tests these rules to verify that each segment receives the correct variation during delivery.

How to hire a Responsys Development specialist on Upwork

Step 1: Post a job

Define your Oracle Responsys integration and campaign automation needs clearly to attract qualified developers. The Job Post Generator powered by Uma™, Upwork's Mindful AI drafts a complete post from a few sentences describing your requirements. You can write a new post, update a saved draft, or reuse an existing post to start the hiring process.

  • Specify whether the role focuses on building program workflows, configuring REST/SOAP API integrations, or designing message templates in Responsys Message Designer.
  • List required technical skills such as HTML email coding, dynamic content rule configuration, and experience with profile list data imports.
  • Clarify if the developer must manage Content Library assets or automate campaign schedules using specific Responsys API endpoints.

Step 2: Evaluate candidates

Review portfolios for evidence of complex multi-step marketing logic and clean API integration code. Uma runs instant video interviews and builds shortlists with side-by-side comparisons to help you assess technical fit quickly.

  • Look for examples of responsive email templates built with Visual Template Designer that render correctly across major email clients.
  • Check for documented cases where the candidate mapped supplemental data fields and scheduled automated import jobs without errors.
  • Verify experience with tracking variables and data switches within program workflows to handle conditional routing logic.

Step 3: Interview your top choices

Discuss specific technical challenges related to Oracle Responsys architecture and data handling. Schedule and conduct interviews within Upwork Messages to receive an immediate transcript and summary after each conversation.

  • Ask how they troubleshoot failed data imports or resolve mapping conflicts between external databases and Responsys profile lists.
  • Request examples of how they structure REST API calls to update campaign resources or manage content library assets programmatically.
  • Discuss their approach to testing dynamic content rules to ensure personalized messages display correctly for different audience segments.

Step 4: Agree on scope and begin work

Set clear milestones for workflow configuration, API development, or template creation before starting. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.

  • Define deliverables such as fully tested program workflows, exported HTML email templates, or documented API integration scripts.
  • Establish a schedule for data import job configuration and validation to ensure audience segments update correctly before campaign launches.
  • Agree on criteria for accepting dynamic content configurations and verifying that personalization logic functions as intended in test sends.
