Your Shopify store probably has a list of things that need fixing, changing, or connecting to other tools — and your team doesn't have the time or the right skills to handle them. That's what I do. I take on the everyday technical work that doesn't get done: customizations the theme can't handle, automations that should already exist, integrations with the tools you already pay for, and the "this should just work" problems that don't. What I help with: - Store & theme customization (beyond what the editor allows) - Shopify Flow + custom automation workflows - Integrations between Shopify and any external tool (email, CRM, ERP, payments, logistics, AI) - Third-party app setup, configuration & troubleshooting - Custom features no app on the market offers - Data migration and sync between platforms - Headless storefronts with Next.js (when you need full frontend control) How I work: clear scope before we start, fast replies, clean code your team can maintain, no surprises on the invoice. Stack: Shopify · Liquid · Node.js · TypeScript · React · Next.js · GraphQL · Webhooks · OpenAI API 🇵🇪 Based in Peru. Native Spanish. Written technical English. Voice calls in Spanish. Send me what you need done — even if it's just a list with no clear plan. We'll figure it out from there.

I’m a Full-Stack Engineer with rich experience building and maintaining web applications that run in production and support real users. I’ve worked on projects from initial idea all the way to deployment, as well as taken over existing systems that needed restructuring, performance improvements, or long-term stabilization. Over the years, I’ve built SaaS platforms, admin dashboards, e-commerce systems, real-time applications, internal business tools, and automation solutions. I’ve worked in environments where stability and scalability truly mattered, which shaped the way I approach development. I don’t rush into writing code — I first think through the structure, potential edge cases, and long-term impact of decisions, because fixing poor architecture later is always more expensive than doing it right from the beginning. I care about clean structure and maintainable systems. I avoid quick fixes that create technical debt and instead focus on building solutions that remain readable, scalable, and easy to extend months down the line. Whether I’m improving an existing codebase or building something from scratch, I aim to leave the system better organized and more stable than I found it. Because I work comfortably across the entire stack, I think in terms of complete systems rather than isolated tasks. That helps prevent disconnects between different parts of a project and results in smoother, more predictable development. Clients usually appreciate that I communicate clearly, stay consistent, and take ownership of what I build. I focus not just on delivering features, but on understanding the actual business goal behind them and implementing solutions that truly support it. If you’re looking for someone reliable, structured, and serious about quality — someone who treats your project like a real product rather than just another gig — I’d be glad to work with you.
