mrkaluzny

Wojciech Kałużny (mrkaluzny) is a developer and designer based in Poland offering website development, performance optimization, and WordPress maintenance. He works with real estate companies, marketing agencies, e-learning platforms, and small- to medium-sized businesses across Europe. His projects range from corporate site redesigns to custom property management systems and mobile applications. Clients describe him as responsive and detail-oriented; one project manager noted "quick responses, no issues working during evenings and fast deliveries."

Services and capabilities

Kałużny offers three main service tracks. Website Development includes custom WordPress builds and bespoke systems tailored to client workflows. His 2E Group project, completed in 2022, featured a custom page builder supporting 18 modules so the client could create and update investment property pages independently. The Sembiotic site (2023) used modular WordPress with video testimonials and customizable landing page templates. For BergeSag (2024), he integrated a Norwegian real estate marketplace (Finn.no) to auto-sync property listings across platforms.

Performance Optimization focuses on speed and SEO. A BerlinGreen testimonial noted that "both GTMetrix and Google PageSpeed ranking doubled" after his work, with all errors fixed. WordPress Maintenance covers security hardening, performance tuning, and automated server updates.

He also offers roadmapping services to define goals and conversion pathways before development begins.

Notable work

BergeSag (2024): Revamped the online presence for a Norwegian real estate firm after their previous solution underperformed. Delivered two unified WordPress sites (Berge-hus and Berge-hytta) integrated with Finn.no, eliminating manual property listing updates and expanding market reach.

Sembiotic (2023): Built a modular WordPress site for a Polish ad campaign management company. The platform includes custom landing page creation, video testimonials, and a content management system so the team can add pages without technical help.

2E Group (2022): Created a custom page builder system with 18 different modules for a Polish real estate developer. The system lets them create and manage investment property pages independently, with dynamic logos, colors, headers, and footers.

Other projects in his portfolio span e-learning platforms (AngelsTeach), native mobile apps (Slimwonen energy monitoring, MDG Design iPad app for Viega), department store redesigns (Steen & Strøm in Oslo), and school websites (Waterdown Montessori in Ontario).

How they work

Kałużny typically starts with a discovery call and collaborative workshopping to understand business objectives and site strategy before building. Project minimums begin at US $5,000 for website development; WordPress maintenance starts at US $59/month. He works with clients across different time zones and mentions availability for evening calls. His portfolio suggests he collaborates with design agencies (he worked with PYX on the BergeSag project) rather than operating as a full agency.

Team and credentials

Kałużny is a solo operator or very small team. He writes technical blog posts on web performance and modern JavaScript (Alpine.js, Remix, Cloudflare issues), suggesting hands-on technical depth. No certifications, partner statuses, or team size beyond his own name are mentioned in the source material.
