⚡ Response under 1 hour during your business day
I don't just build and disappear.
Many of my strongest client relationships continue long after the first project - with ongoing development, new features, integrations, optimization, maintenance, AI implementation and technical problem-solving.
🔄 LONG-TERM DEVELOPMENT PARTNERSHIPS
Many clients don't need a developer for one project.
They need someone who can stay with the product and keep improving it.
I work with founders, agencies and growing businesses on ongoing engagements covering:
→ New feature development
→ Product improvements
→ WordPress and Shopify development
→ SaaS development
→ AI integration and AI agents
→ API integrations
→ Business automation
→ Performance optimization
→ Security and technical maintenance
→ Bug fixing and technical troubleshooting
→ Third-party integrations
→ Technical SEO and Core Web Vitals
→ Migration and modernization
Because I already understand your codebase, infrastructure, business logic and goals, future work can move faster with less onboarding and less management.
Engagements can range from ongoing monthly development to dedicated development capacity for agencies and growing products.
👤 FOR FOUNDERS
You need more than someone who can complete a development task.
You need a technical partner who understands your product, your users and your business well enough to keep improving it as you grow.
I can take your project from Figma, requirements, spreadsheet or rough idea to production, then stay involved for ongoing development, maintenance, integrations, automation, performance improvements and new features.
You don't need to hire and manage an entire technical team for every stage of your product.
I can work as your ongoing development partner, giving you experienced technical capability without the overhead of a full-time engineering team.
🤝 FOR AGENCIES
I can be the build team behind your studio.
I provide white-label WordPress, Shopify, React, Next.js, SaaS, AI and automation development, with NDA available on request.
Your brand stays on the work, your client never needs to know I exist, and you can take on projects without constantly sourcing and managing new developers.
More importantly, I can become a reliable extension of your team.
You can send work continuously, keep the same technical partner across multiple client projects, and avoid repeatedly explaining your development standards, processes and expectations to new freelancers.
I can work from your designs, specifications or client requirements and fit into your existing delivery process.
🛠️ WHAT I BUILD
🤖 AI Integration and AI Agents
AI assistants, intelligent search, lead qualification, knowledge-base and document retrieval, content generation, LLM integrations, AI-powered workflows and agentic systems.
SaaS and Custom Software
MVPs, customer portals, business dashboards, workflow applications, calculators, configurators and internal systems designed around specific business requirements.
WordPress and WooCommerce
Custom WordPress development, WooCommerce stores, custom post types, ACF Pro, membership and subscription systems, multilingual websites, custom business logic, third-party integrations and performance optimization.
This is not template assembly. I build WordPress systems around the actual business requirements.
Shopify
Custom Shopify stores, Shopify theme development, Liquid customization, app integrations, Shopify Plus and conversion-focused eCommerce experiences.
React, Next.js and MERN
Modern web applications, SaaS products, dashboards, client portals, marketplaces, booking platforms, internal tools and custom business applications.
I focus on building products that can continue evolving rather than creating an MVP that needs to be thrown away at version two.
