You will get I will build, fix or optimize your backend, APIs and cloud deployment
Project details
I will deliver a clean, secure and fully optimized fix or upgrade for your website or backend system. Unlike generic developers who only patch issues superficially, I specialize in deep technical diagnosis, scalable architectures, and permanent solutions.
I’ve built complete multi-server ecosystems, dashboards, APIs, authentication systems, cloud deployments, file-management modules, logging tools, and automation pipelines from scratch—so when I fix something, I ensure it stays stable, fast, and future-proof.
Your project will receive precise analysis, industry-grade code quality, transparent communication and delivery that truly solves the problem at its root.

About Xtremertx
Full-Stack Web & API Developer | Backend, Cloud & Automation
San Fernando, Chile - 8:06 am local time
I develop complete solutions: authentication, user roles, databases, cloud deployments, dashboards, automation and file processing.
Over the last year I have built a full digital ecosystem from scratch, including:
Multi-server API architecture (auth, file management, updates, logs, admin tools)
Web platforms (Next.js / React) with dashboards, roles and permissions
Backend systems for uploads, subscriptions, documents, and user tracking
Cloud deployment on Vercel, Render, and HuggingFace Spaces
Python desktop apps for reading, processing and validating files
Security layers, incident reports, update systems and admin consoles
What I can do for you:
✔ Build or fix backend systems
✔ Develop REST APIs (Python / FastAPI / Node.js)
✔ Deploy and optimize apps in the cloud
✔ Create dashboards, admin panels and automations
✔ Integrate AI features, cloud tools or custom logic
✔ Debug, refactor and optimize existing code
✔ Improve performance, security or architecture
Tech stack:
Python · FastAPI · Node.js · JavaScript · React · Next.js · Vercel · Render · HuggingFace · JSON/NoSQL · Cloud Deployment
I take every project seriously, work with precision, and deliver clean, maintainable solutions.
If you need someone who can solve complex problems, build systems from scratch or rescue a project that’s stuck — I can help.
