Jafet Prieto Gonzalez

Senior Full-Stack Developer — Web Applications, WordPress & Shopify

I’m a senior full-stack developer with over 10 years of experience building custom websites, web applications, and e-commerce platforms from initial architecture to production. My technical background spans Node.js, TypeScript, PHP, REST APIs, and both relational and document-oriented databases. I also specialize in custom WordPress and Shopify development, including themes, plugins, WooCommerce systems, and Liquid integrations built for real world production use. Over the years, I’ve led development teams, managed more than 80 live sites simultaneously, and delivered projects across various sectors, including agency, SaaS, real estate, and security.

Profile

The technical part is rarely the hardest part.

Most web problems are not technology problems. They are scoping problems, prioritization problems, or the result of decisions made three years ago by someone who no longer works there. I have spent a decade untangling those situations and building the kind of systems that create fewer of them.

I take technical ownership seriously. That means understanding the business reason behind a feature before writing a line of code, flagging the approach that will cause maintenance debt six months from now, and knowing when the right answer is a custom build versus a configuration change. I regularly work with marketers, designers, and non-technical stakeholders, and I have learned how to translate between what a business needs and what the code should actually do.

I move fast without cutting corners, and I can operate independently or slot into an existing team without friction. If a project has an unclear scope, I help define it. If it has a hard deadline, I structure the work to hit it.

01

Custom web applications

Full-stack systems built end to end, with a strong focus on maintainability, performance, and long term scalability. Designed to support real business needs.

02

WordPress & Shopify engineering

Custom themes and plugins built from scratch. This includes WooCommerce systems, Liquid storefront, and complex platform development that requires an understanding of how WordPress and Shopify actually work under the hood.

03

Integrations & automation

Third-party APIs, CRM connections, payment systems, and workflow automations designed to hold up under real operational load. I map the data flow and failure points before writing a line of code.

04

Performance & optimization

Core Web Vitals, technical SEO, Cloudflare configuration, and conversion improvements, all guided by real data. I identify what slows a site down or hurts conversions, then fix the root cause.
