About this gig
Are you frustrated by the limits of off-the-shelf Shopify apps?
I'm a full-stack engineer who designs public and private Shopify apps without relying on boilerplate code.
What I Provide
- Custom app development: I build modular, secure, and SEO-friendly code using Laravel, Node.js, React, Vue, PHP, and GraphQL/REST APIs.
- Conversion-boosting features: I analyze your needs and research top-ranking apps to create features like:
- Subscription billing
- Dynamic pricing
- Custom checkout flows
- Multi-currency support
- Third-party integrations
What You Can Expect
- Clean documentation & maintainable code: I ensure your solution meets Shopify App Store requirements.
- Transparent timelines: An MVP typically ships within 7 days, and I won't promise unrealistic delivery for complex projects.
- Flexibility: I can customize your existing store theme or build a headless app that works seamlessly with mobile and POS.
- Ethical standards: I won't work with illegal, adult, or gambling content.
Why Choose Me
- Direct collaboration: You work directly with me, no outsourcing or AI gimmicks.
- Agile development: Expect honest communication, iterative updates, and 24/7 support after delivery.
