15+ Years Exp | Full Stack, Mobile & Web Apps | MVP | Cloud & AI
I help companies, agencies, and organizations build, improve, and rescue complex websites, digital platforms, and business-critical workflows. I’ve spent many years on the technical side of agency work, leading projects that go well beyond standard website development: custom WordPress and WooCommerce platforms, third-party integrations, membership systems, directories, marketplaces, booking workflows, CRM and marketing automation, data migrations, and internal operational tools. I can step in as a senior full-stack developer, technical lead, or fractional CTO—whether you need someone to build a new solution, take ownership of an inherited codebase, resolve a difficult implementation, or translate business requirements into a practical technical roadmap. My work commonly includes: • Custom WordPress and WooCommerce development • Complex forms, user portals, memberships, directories, and marketplaces • Payment, booking, subscription, and e-commerce workflows • CRM, ERP, API, and third-party platform integrations • Salesforce, ActiveCampaign, Brevo, Gravity Forms, and marketing automation • Custom plugins, PHP, JavaScript, REST APIs, ACF, and advanced data structures • Performance optimization, debugging, security, and legacy-code stabilization • Technical discovery, architecture, project planning, and developer oversight • AI-powered website features, workflow automation, and LLM integrations For AI projects, I focus on practical implementations tied to a real business outcome—not AI for its own sake. This can include intelligent search, document and knowledge-base assistants, content-processing workflows, structured data extraction, internal support tools, AI-assisted customer experiences, and integrations that connect language models with existing websites, software, and company data. Clients bring me in when a project requires more than someone who can simply follow a design or install plugins. I’m comfortable working directly with stakeholders, identifying technical risks, challenging unclear requirements, coordinating with designers and developers, and carrying a project from discovery through launch. My background includes work for startups, nonprofits, established businesses, and agency clients, including projects connected to organizations and brands such as Stanford University and Bill Nye. I’m equally comfortable joining an existing team or independently owning the technical delivery. If you have a complex build, a platform that has outgrown its current setup, or an operational workflow that should be automated, send me the details. I’ll give you a clear assessment of what it will take, where the risks are, and the most practical way forward.
