Where design meets technology

My name is Marcin Szewczyk-Wilgan – full-stack designer, certified UX and IT specialist. I combine 25 years of design expertise with modern technology and UX. My specialization includes printed publications, websites, and digital solutions that perform. From strategy to launch.

Typography / Graphic Design

Make your content impossible to ignore

I am a press design expert, focusing on readability, visual appeal, and usability of printed publications and electronic media. I optimize every detail: from typeface selection to automated workflows, so your publications look professional and are easy to produce.

What I deliver:

  • Good typographyI know how to answer questions, and I also know which questions to ask to deliver distinctive and effective design solutions. Not just for large corporations, but also for small businesses seeking the perfect fonts for a specific application.
  • Magazine, book and raport designI design layouts for trade magazines, with over twenty titles in my portfolio. My work includes beautifully typeset books—complex scientific, legal, and technical publications with tables, charts, and mathematical formulas. From concise one-pagers to comprehensive analyses, my reports combine solid research methodology with clear visual form.
  • Desktop publishing services - DTPI have extensive years of experience collaborating with editorial teams both domestically and internationally. I have an excellent understanding of publishing, proofreading, and technical matters. I pay attention to details. I create custom text processing systems and workflow automation.
  • Text data processingI build tools for processing complex documents and data, transforming unstructured content into organised formats. I design solutions for text parsing, extraction, and transformation, tailored to the requirements of publishing or analytical workflows. I implement and develop OCR systems for document digitisation.
  • Automated publishing workflowsUsing tools for content analysis, complex text pattern matching, and conditional style and format transformations, I create systems that optimise the publication typesetting process and minimise the effort and time required to produce it.

Web Design and Web Development

Websites that look great and actually work

I build complete digital solutions, from design to deployment. Every website I create is user-tested, mobile-optimized, and built on reliable technology (WordPress / WooCommerce). Plus, I handle all the technical details: hosting, security, mass storage and backups.

What you get:

  • Custom WordPress sites and online storesI design and implement websites and online stores based on WordPress and WooCommerce, tailored to individual client needs. I create scalable solutions that are easy to manage and optimised for performance.
  • Secure, fast hosting setup (FreeBSD / Linux)I configure and administer servers based on FreeBSD and Linux, ensuring security, stability, and high performance. I maintain optimised hosting environments, regular updates, and infrastructure monitoring. I manage data storage systems using EXT3/4, UFS2, and ZFS file systems, selecting solutions based on performance, reliability, and scalability requirements.
  • Conversion-focused UX designI design user-centred interfaces that drive business goals. As a certified UX designer, I combine aesthetics with functionality, creating user journeys that maximise conversion and engagement.
  • Ongoing maintenance and updatesI ensure the continuity of services through regular maintenance, security updates, and performance optimisation. I respond to changing needs and ensure compliance with the latest standards.
  • Copywriting and SEO activitiesI create content that engages audiences and is optimised for search engines. I combine keyword strategy with natural, persuasive messaging that supports marketing goals. Years of editorial experience allow me to ensure linguistic accuracy, stylistic consistency, and clarity of message.

UX/UI Design

Products people actually want to use

As a certified UX designer I create experiences based on real user needs, not assumptions. Through research, testing, and iteration, I ensure your product is intuitive, accessible, delivers measurable results, and achieves your business goals. No fluff, just solutions that work.

My process includes:

  • User research and competitive analysisI conduct in-depth user research to understand behaviours, motivations, and pain points. I analyse competitors to identify market gaps and opportunities, providing a solid foundation for design decisions.
  • Information architecture and user flowsI structure content and navigation to create logical, intuitive pathways through your product. I map user journeys that minimise friction and guide users efficiently towards their goals.
  • Usability testing and optimizationI validate design solutions through real user testing, identifying issues before they reach production. I iterate based on data and feedback, continuously refining the experience.
  • Interactive prototypes for testingI build clickable prototypes that simulate the final product, enabling early validation of concepts. I work with industry-standard tools like Figma and Axure, and leverage AI-powered platforms such as v0, Lovable, and Bolt to accelerate the prototyping process. This approach saves development time and reduces costly revisions later in the process.
  • Interface design that convertsI design visually compelling interfaces that balance aesthetics with usability. Every element serves a purpose, guiding users towards actions that support your business objectives.

AI Integration

Work smarter, not harder

I intensively and wisely integrate AI tools to work more efficiently, ideate faster, and deliver more refined solutions. This approach allows me to focus on creative problem-solving while automating routine tasks. I see AI as our co-pilot, not our replacement.

How I use AI:

  • Data-driven decision makingI use AI to analyse user behaviour, market trends, and performance metrics, transforming raw data into actionable insights. I build automated workflows in n8n to collect, aggregate, and route data for AI-powered analysis. This enables informed decisions based on evidence rather than intuition.
  • No-code/low-code developmentI leverage AI-powered platforms and no-code tools to rapidly build functional applications and automations. This accelerates delivery timelines and allows for quick iteration without extensive coding overhead.
  • Usability testing and optimizationI employ AI tools to analyse user interactions, identify friction points, and generate optimisation recommendations. This data-driven approach enables continuous improvement of user experiences at scale.
  • Smart content processingI implement AI solutions for text analysis, summarisation, and transformation, streamlining content workflows. This includes automated formatting, translation assistance, and intelligent document processing.
  • Automated quality assuranceI integrate AI into testing and review processes to catch errors, inconsistencies, and accessibility issues early. This ensures higher quality deliverables while reducing manual review time.

In progress: GIS, PostgreSQL and spatial data

Full stack for geospatial projects

I am currently developing comprehensive competencies in Geographic Information Systems and their database infrastructure. I combine QGIS skills with advanced PostgreSQL administration and the PostGIS extension. This combination will enable me to deliver the full cycle of geospatial projects — from data acquisition and processing, through spatial analysis, to map visualisation and publication.
