Mr. Star WEBMASTER

Mr. Star WebMaster is run by Deivison Estrela, a systems architect based in Brasília, Brazil, operating under the name Mr. Star. The business is structured as a small team (1-10 people) working with B2B companies and retailers looking to consolidate technology, cut operational bureaucracy, and prepare for tax-system changes affecting invoicing in Brazil. Rather than offering isolated services, the work is presented as an integrated ecosystem combining marketing, a proprietary SaaS platform, and strategic consulting for businesses at different stages of technological maturity. Services described include strategic consulting covering process mapping, technology stack analysis, and digital action planning; Full Stack web development using Laravel/PHP; and high-end landing page and e-commerce development aimed at conversion and lead capture, with attention to Core Web Vitals and load-time performance. A core offering is the WebStar System, a cloud-based ERP and POS platform that integrates physical and online stores on a shared database, handles inventory control, and includes native NFe/NFCe fiscal invoice issuance built for Brazil's digital accounting requirements. Case examples mention replacing multiple outdated software tools with the WebStar System and redesigning B2B SaaS landing pages for faster load times. Engagement is organized into tiers—diagnostic consulting, full system implementation with technical support, and digital project work—depending on a client's stage of growth.
