AI & Automation
Automating workflows and deploying intelligent agents that learn, adapt, and execute — so your team can focus on what matters most.
AI and automation services help businesses replace manual, repetitive workflows with intelligent software agents that learn, adapt, and execute autonomously. At KAUFAST, this means building WhatsApp bots that handle bookings and payments via Stripe or Mercado Pago, deploying LLM-powered assistants using GPT-4o, Claude 4.5, or Gemini 2.5 that process thousands of daily queries without human intervention, and connecting disparate systems into seamless automated pipelines. Typical implementations include customer support agents that resolve tickets autonomously, lead qualification bots that route prospects in real time, and compliance monitors that flag regulatory changes across multiple jurisdictions. Automation projects typically ship in 2–4 weeks; full agent systems take 3–6 months. Every agent includes decision boundaries and a full audit trail — freeing your team to focus on work that actually requires human judgement.

Infrastructure & Security
Scalable cloud architecture, lightning-fast sites, and enterprise-grade security — built to grow with your business and protect what you've built.
Infrastructure and security services ensure your technology is fast, reliable, and protected against modern threats. KAUFAST architects cloud-native systems on AWS, Google Cloud, and Vercel with 99.99% uptime targets, auto-scaling, and CDN delivery via Cloudflare. Security is implemented from day one following OWASP Top 10 standards, GDPR and CCPA compliance frameworks, penetration testing, and continuous threat monitoring. Performance is measurable: our managed projects average 97+ Google PageSpeed scores — compared to an industry median of 50 for mobile (HTTP Archive Web Almanac 2025). Cloud migrations are structured in phases to ensure zero downtime during transition. Timelines range from 4 weeks for a performance overhaul to 6–12 months for full enterprise infrastructure migrations. Every deployment includes monitoring dashboards, alerting, and incident response with a 30-minute first-response target.

Software & Data
Bespoke software development and data-driven insights that turn raw information into actionable intelligence for smarter decision-making.
Custom software and data services turn your unique business requirements into tailored platforms that no off-the-shelf product can match. KAUFAST builds multilingual web applications in Next.js and React, native iOS apps in Swift, native Android apps in Kotlin, SaaS products with multi-tenant architecture, and data analytics dashboards that aggregate from multiple APIs in real time. Every project ships with WCAG 2.1 AA accessibility compliance, multilingual SEO across up to 13 locales, and PageSpeed scores above 90 on Google's performance audit. Data analytics work covers custom dashboards, automated reporting pipelines, and event tracking integrations with GA4, Mixpanel, or custom data warehouses. Projects are scoped in writing before development begins — fixed scope, fixed timeline, changes handled via a formal process. No scope creep, no surprise invoices.

SEO & Digital Visibility
Technical SEO, content strategy, and link-building that move your site up Google's rankings — and keep it there.
SEO and digital visibility services turn your website into a consistent source of qualified, organic visitors. KAUFAST delivers technical SEO audits identifying crawl errors, duplicate content, and Core Web Vitals issues; content strategies mapped to keywords your customers actually search; international SEO across 13 locales for multilingual businesses; and local SEO optimisation for Google Business Profile rankings in Barcelona, London, and key European cities. Technical SEO, on-page content, and link acquisition are managed as one integrated programme — not separate services.

Every programme includes monthly position tracking, competitor benchmarking, and plain-English reporting.
