About Roger

Looking to optimize your business with Artificial Intelligence, automate manual processes, or launch a website that truly ranks and sells? I can help.

I am a Full Stack Developer (React, Node.js, TypeScript, Python) focused on being the "technical partner" for companies and entrepreneurs who need agile solutions. I don't just write code; I understand your business objectives.

My differentiator:
Execution speed. I integrate advanced AI workflows (Claude) into my daily development. This allows me to increase my technical efficiency by 50% and deliver high-quality software, automations, or websites in record time, reducing your costs.

How I can help you (Specific projects and deliverables):

AI Audit and Integration: I analyze your business to identify which manual processes can truly be automated. I add AI agents or LLMs only where they genuinely add value and save your team hours.

Rapid Custom Software: Agile development of internal tools, management dashboards, or MVPs tailored to your company's logic.

E-commerce and Landings: Creation of Shopify apps, online stores, and simple yet ultra-optimized Landing Pages for SEO and conversion.

Main Technological Stack:

Frontend: React, Next.js, TypeScript, TailwindCSS.

Backend and Databases: Node.js, Express, Python, PostgreSQL.

AI and Automation: Claude, AI Agents, Prompt Engineering.

I currently balance my main activity as a B2B technical consultant with developing specific projects. I work independently, always prioritizing my clients' return on investment.

If you have a specific technical challenge, send me a message and we'll evaluate the best solution for your business.
