You will get I will fix bugs and errors in your React, Node.js or Express app
Project details
Is your React, Node.js or Express application throwing errors, refusing to build, or behaving unexpectedly?
I help startups, agencies, and small businesses fix bugs, resolve deployment issues, and ship features in React and Node.js/Express applications. I work full-time maintaining a production CRM/ERP system for a law firm, and I build my own products outside of that role, so I know how to find the real cause of a problem, not just patch it.
Stack: React + Vite, Node.js + Express, PostgreSQL, MongoDB, Google Cloud Run, Vercel, Git & GitHub workflows, REST APIs.
I can help with:
• Frontend bugs, broken builds, and unexpected behavior
• Backend/API errors and database issues
• Deployment problems on Vercel or Google Cloud Run
• Small feature implementation, end to end
Send me a message describing your issue and I'll give you a clear plan before we start.

About Daniel
Full-Stack Developer | React, Node.js, PostgreSQL & AI Integration
San Salvador, El Salvador - 3:42 pm local time
I help startups, agencies, and small businesses fix React applications, troubleshoot Node.js/Express APIs, resolve PostgreSQL/Supabase issues, and deploy projects to platforms like Vercel and Google Cloud Run. I also work with AI/LLM integrations, from prompt engineering to AI-powered features inside existing apps.
My focus is on small, clearly defined development tasks that can be delivered quickly and reliably. Whether you're dealing with a broken deployment, API errors, authentication issues, Git conflicts, database bugs, AI feature requests, or frontend problems, I work to identify the root cause and implement a clean solution.
My production stack includes:
• React + Vite
• Node.js + Express
• PostgreSQL & Supabase
• AI/LLM integration & prompt engineering
• Google Cloud Run
• Vercel
• Git & GitHub workflows
• REST APIs
Professionally, I work full-time developing and maintaining a custom CRM/ERP platform for a law firm. My day-to-day responsibilities include implementing new features, integrating backend services, managing PostgreSQL databases, deploying updates, and improving internal business workflows.
Outside of my full-time role, I build my own software products. One example is PistoApp, a personal finance application featuring AI-powered transaction parsing, voice input, push notifications, and modern cloud deployment. I also operate DigitalFlow, where I develop websites and web applications for small businesses.
I value clear communication, realistic timelines, and delivering solutions that are easy to maintain—not just quick fixes.
If you're looking for someone to solve a specific React, Node.js, AI integration, deployment, or backend issue without unnecessary complexity, I'd be happy to help. Send me a message, describe the problem you're facing, and let's get it resolved.
