I build and maintain Shopify Plus stores for DTC brands, from custom theme development and product page builds to private apps, API integrations, and performance optimization. I work with Claude Code as part of my core dev workflow, which means I work fast and efficient without cutting corners on quality. A few stores I currently work on or have built: - High Camp Supply (Shopify Plus, ongoing development) - Hevias (Shopify Plus, ongoing development) - Fastlane Trade (built from scratch, custom PDP, slide cart with product selectors) - The Vocal Market (headless Next.js/Shopify marketplace, my own project) - Multiple DTC brands through Timberline Brands (shared Shopify infrastructure) - PuriPet (German premium pet supplement brand) My stack: Liquid, JavaScript, HTML/CSS, React, Next.js, Node.js, Shopify GraphQL API, REST API, private/custom Shopify apps. I also handle analytics setup (GA4, conversion tracking, custom pixels), A/B testing, and CRO. Beyond development I have a strong creative background: 15 years in music production and content creation, which means I think about design, UX, and visuals naturally. I've created ad creatives, brand visuals, and AI-generated video content for e-commerce brands. If you need someone who understands both the technical and the creative side of your store, that's where I'm strongest. I'm based in the Netherlands (CET), respond fast, and prefer long-term working relationships where I can take real ownership of the codebase.

Hey i'm Javad, a full-stack and mobile developer with 5+ years expriance in hand my tech is Nextjs, React, FastAPI, MongoDB/PostgreSQL, and Flutter. I've developed more than five services as a freelancer. Problem solving and creativity are my passions. I do this job not just for the money, I do it because I love it.

I build AI systems and automations for agencies and SaaS teams, from custom AI apps to end-to-end workflow automation. Two things I do: full-stack AI builds (chatbots, RAG systems, AI-powered tools with real frontends and APIs) and automation engineering in n8n (lead gen pipelines, CRM integrations, AI workflows). Focus areas: lead generation, CRM integrations (HubSpot, Pipedrive, Airtable), and AI-powered systems using OpenAI and Claude. If you have a repetitive process eating your team's time, or an AI product idea you need built properly, I can usually ship something working within a week. Recently built: Lead qualification system for a B2B agency. Inbound leads auto-enriched via Apollo, scored by GPT-4 against their ICP, and routed to the right sales rep in HubSpot. Saved 18 hours/week and dropped response time from 2 days to 15 minutes. AI-powered outreach pipeline for a SaaS team. Pulled prospects from Apollo, personalized emails using company data + GPT-4, sent via Instantly, tracked replies back into Airtable. Tripled their reply rate vs their old template approach. Tools: n8n, OpenAI, Claude, HubSpot, Pipedrive, Airtable, Apollo, Instantly, plus standard full-stack (React, APIs, databases) for custom builds.

I've built and scaled automation systems for 7-and-8-figure businesses, including Intersport (14 Billion in Revenue for 2023), using cutting-edge tools like GPT-5, n8n, Make, Zapier, and Node.js. I've created dozens of systems - many of them responsible for hundreds of thousands in revenue and/or savings. My favorites include: Automatic lead gen & outreach systems (to magically source leads, qualify them, and reach out to them using email/SMS/social media with customized, AI-generated icebreakers), Business process automation systems (to compress multi-day workflows into minutes, automate data transformations, streamline operations, and eliminate manual work that costs thousands in labor hours), Customer support & engagement systems (to automatically handle customer inquiries, manage onboarding workflows, schedule social media content, and integrate with CRMs for seamless client management). I also have experience with more or less every major automation and CRM platform (think n8n, Make, Zapier, Airtable, Monday, ClickUp, HubSpot, Go High Level GHL, etc) and have built dozens of custom API integrations for added functionality.
