Know4Use is a personal Spanish-language technical knowledge blog maintained by Jesús Zuleta. Its tagline emphasizes "usable knowledge", and its content focuses on software development, DevOps, cloud infrastructure, SRE, AI applications, automation, PKM (personal knowledge management) and related topics. It is more of a combination of a technical lead's personal brand homepage, public notes and project portfolio, rather than a standard SaaS product.
The site includes the author's introduction, work experience, tech stack, project showcase, blog posts and a contact form. Featured projects include VoxDrop, an on-device speech-to-text tool for KDE; the Know4Use Blog built with Astro and Cloudflare; a K3s/NixOS homelab; DSPy-based sentiment analysis; an Obsidian PKM system; trading automation; an AI Governance PoC and more. The blog currently features short articles on topics like terminal productivity, Astro, and learning methods for automation, with a focus on sharing practical experience.
We found no memberships, subscriptions, paid courses or explicit consulting pricing when crawling the site. All currently public content is free to access. Only a contact entry point is provided for consulting services, with no disclosed pricing, delivery timelines or service packages.
The biggest advantage is its very clear positioning. The author has held roles including Principal Engineer, Engineering Director, and Head of Cloud, with a tech stack covering TypeScript, Python, Go, Rust, Kubernetes, Terraform, AWS, Cloudflare, DSPy, RAG, and AI Governance, giving him strong credibility. The site itself is built with Astro, EmDash CMS, and Cloudflare Workers/D1/R2, which aligns perfectly with his engineering practice profile.
The downside is that the site is primarily focused on personal branding, and the total volume of content is still limited based on our crawl. Some placeholder text such as "0+ years of experience" suggests unfinished page rendering or uncompleted statistics. The Spanish-language content creates a barrier for Chinese readers, and as a consulting landing page, it lacks clarity on case outcomes, client testimonials, service scope, pricing and SLAs.
It is suitable for software engineers, DevOps/SRE professionals, cloud native practitioners, technical managers, AI engineering practitioners, and readers interested in Obsidian/PKM, homelab, self-hosting and modern development toolchains. Companies looking to preliminarily assess the author's consulting capabilities in AI, infrastructure or engineering leadership can also use this site to form an initial impression.
The site is deployed on Cloudflare Workers. It can usually be accessed directly from mainland China, but stability depends on your network operator and Cloudflare routing. Our crawl found no evidence of it being blocked, nor that a proxy is mandatory. Content is primarily in Spanish, so Chinese users may need browser translation to read it.
