Fullstack developer with over 20 years of experience in web and mobile applications. My main expertise is Wordpress, PHP, React and Angular, but the last year has been full of work related to AI. My level of seniority allows me to develop apps with high quality and speed, provide business-oriented consultancy to help you reduce costs but achieve technical excellence, and transfer knowledge across a broad spectrum of topics related to software engineering for web and mobile applications. I’ve led big, medium and small projects feel free to ask me about them, I can also refer to clients if you want to know what the experience of working with me is like. I care about my work being a good investment for you, so my commitment is to reduce effort, increase and put as much expertise as possible. In the last 18 months, I have helped companies to integrate Artificial Intelligence AI products, functionalities into applications for the web or mobile devices. Recent projects have involved the implementation of AI, LLM agentic workflows (using Azure, Zappier, GCP), including the usage and the implementation of MCP servers. These projects generally involve the execution of autonomous actions by the agent and the intelligent interaction with end customers via conversational interfaces, enabling automated and context-aware workflows. Those projects have been usually integrated into Web Apps created in React, Angular, Wordpress or PHP, Java, Javascript backends. I also have an extensive portfolio in Wordpress development, including e-commerce storefronts implementation, integration Wordpress to 3rd parties or legacy systems, custom plugin development, custom theme development, hardening of existing sites to avoid cybersecurity issues, rescuing attacked or hacked websites, rapid prototyping and custom component implementation using Divi, Bricks, Elementor, Gutemberg, etc. How can I help your project succeed? 1. Implemention of AI-powered powered systems 2. Wordpress: Websites, plugins, SEO, security, eCommerce, WooCommerce, themes, responsive, hosting, backup, performance, optimization, speed, cache, payment gateway, SSL. 3. React, Angular: JavaScript, JSX, Componenst, SPA, Next.js, Remix, Vite, Webpack, Babel, TypeScript, Redux, SSR, Jest, Tailwind, Material UI, 4. development in Python using frameworks like FastAPI, Flask 5. API integrations, service orchestration, and middleware architecture in platforms whose core languages are Javascript, PHP or Python. 6. Deployment and maintenance of web applications on Microsoft Azure or AWS. If you're looking for a developer with a business vision, proven experience, and a strong focus on results, I'd be glad to work with you.

Java sits at the center of the platforms I build. Spring Boot runs the backend services and APIs, handling business logic, data access, and the core behavior of the system. Many of these platforms pair a Spring Boot backend with Angular on the frontend, forming structured web applications such as internal dashboards, operational platforms, and SaaS systems used by teams every day. Angular provides the application interface while the Java backend manages services, data, and integrations behind the scenes. Python also comes into play when automation or data workflows are needed. Small services and scripts written in Python handle background tasks, integrations, and operational processes that support the main platform. Java and Spring Boot handle the backend services, Angular runs the platform interface, and Python supports automation and background tasks.

I'm a Full-Stack Product Developer who loves building web apps end-to-end — from architectural thinking and development planning to implementation and cost-efficient hosting. From day one to launch, you'll always know exactly where your project stands. I keep the product owner in the loop, and we stay on the same page the whole way. Here's who I usually build for: → Business owners (technical or not) who need a custom web app and want someone to turn the idea into a real, working product. → Founders who need clean, conversion-focused landing pages. → Startups and teams who need an extra pair of hands that can drop into the codebase and ship without hand-holding. This is how I build full web apps in 2026, no bs: Architecture & system design → Custom UI/UX with Claude + Claude Design + Stitch + Figma → Frontend in React/Next + TS + Tailwind + Vitest → Backend in Node + TS + Postgres + Docker + Vitest → Deployed cost-efficiently on Railway. I build AI-native — Claude Code + Spec-Driven Development — which means I plan before I build: a clear spec and a solid architecture first, so you get clean, maintainable code instead of surprises. What I'm experienced with: - Frontend: React/Next + Tailwind + TS - Backend: Mostly Node + TS — and I really enjoy building with Go when a project needs leaner, faster APIs. - Databases: Mostly Postgres; also Firebase, MongoDB, MySQL. - Hosting & Deployment: Railway is my go-to for fast, cost-efficient deploys — I've also worked with GCP and a bit of AWS. - UI/UX & Design: Claude + Claude Design + Stitch + Figma At the end of the day, you're not just hiring a tech stack — you're choosing someone to build alongside. I'm Latino, so I bring good vibes and some laughs to the team, plus engineering I stand behind. So let's keep it simple: a quick call, you tell me what you're trying to build, and I'll give you my honest take — no pressure either way.
