(0 review)Business websites on Astro and custom web apps in React, Spring Boot and Next.js
WebProfessor is a Warsaw-based software house specializing in two areas: business websites and custom applications that companies run on every day. We build websites on Astro, Sanity headless CMS and Cloudflare. They are fast and secure, rank high in Google and AI search, and convert well. We migrate sites from WordPress and other CMSs without losing rankings. We build custom software in React, Next.js and Spring Boot: internal systems, panels for patients, customers and sales, and billing, integrated with the company's other tools. After launch we handle maintenance and development. A website and applications often form one system: from winning customers, through e-commerce and customer service, to internal processes and AI automation. You can start with any part and add the rest in stages. Our deepest experience is in three industries: - Healthcare. For the OpenMed medical centers we built a website with online booking (+43% conversion, +3782% organic traffic) and MedBill, a clinic management system. Plus an e-prescription, sick note and e-referral platform integrated with Poland's P1 e-health system and ZUS. - Automotive. The ClickLease website, with vehicle search, a leasing calculator and supplier offers, raised conversion by 86%. - Education. For Bonapi, a Dutch training center, we moved multilingual sites from WordPress to Sanity and Astro. We also built a system for their training, customers and internal processes, with e-learning. For Egzamido, a platform with subscriptions and a study assistant. 50+ projects, a senior-only team with 8+ years of experience each. We use AI wisely: we work faster without losing quality. Our work combines IT with marketing, strategy, design, UX and conversion optimization (CRO). We always advise and take the initiative. Results are what count: our websites raise conversion by 47.2% on average, with an average ROI of 324% after 6 months. We work with companies from Poland, Europe and the US.Looking for work in Software DevelopmentLocated in Warsaw, PolandFrom €10,000 for Software DevelopmentWorks in multiple industriesSpeaks English, Polish1-10 membersOnix-Systems
