The complete Inertia.js form toolkit: the useForm hook, server-side Laravel validation mapped onto fields, error handling, file uploads, progress and dirty-state warnings — with real code.
How to type an Inertia.js + React app end to end: the PageProps contract, typed usePage and useForm, generating types from Laravel resources, shared props and strict mode in CI.
Two ways to authenticate a React frontend on Laravel: Sanctum with API tokens for a separate SPA, or Inertia.js session auth in a single app. How each works, what it costs, and when to switch.
How to test an Inertia.js app: asserting page components and props in Laravel feature tests, testing validation and auth flows, and component tests on the React side — with practical examples.
How we build and run OneCRMApp, a CRM for insurance agents: why Inertia.js instead of a REST API from day one, the EAV data model for policies, PostgreSQL tuning and what we learned shipping a real SaaS.
Next.js frontend with a Laravel API, or Inertia.js inside Laravel? Deployment models, SEO, team topology and cost — an honest comparison from a team that ships both.
Practical AI deployment in a business: how to design prompts that hold up, what data must never reach a public model, GDPR considerations and where AI actually pays off.
AI implementation cost in 2026: three deployment levels from 3 000 to 150 000 PLN net, what drives the price, 10–20% yearly maintenance and when AI is not worth it.
Business process automation explained: how it differs from digitalisation and AI, which processes to automate first, how to calculate the return and what it costs in 2026.
A WordPress landing page is a single-goal page: a headline with a promise, trust signals, an offer with CTA and a form. A builder (Elementor) is faster and cheaper (1,500–3,000 PLN net); a dedicated project is more efficient (3,000–5,000 PLN). Critical: load speed, one CTA, measurability and A/B tests.
WordPress ecommerce means WooCommerce: a free open-source plugin with no commissions and full ownership of the store and data. Costs: implementation 6,000–25,000 PLN net, store hosting 300–800 PLN/year, plugins 500–2,000 PLN/year. When WooCommerce beats PrestaShop and SaaS — in this guide.
