Markus Gritsch
Last position:
Open-Source Software Engineer & Maintainer at Stealth Startup
Independent, part-time open-source engineering focused on build-time tooling for Next.js, React, MDX, and JavaScript/TypeScript compiler pipelines.
Built next-slug-splitter to optimize content-driven Next.js applications. It analyzes MDX content at build time, resolves component usage, and generates route-specific handlers so pages avoid sharing the full catch-all component bundle.
Created supporting plugins and utilities for scoped MDX transformations, nested component dependency resolution, compile-time refinement, safe ESTree evaluation, and object-graph diffing.
Own architecture, API design, implementation, automated testing, npm publishing, documentation, demos, and performance benchmarking.
Building blocks:
remark-scoped-mdx: Context-aware AST transformations with nested scope isolation, typed component registries, and prop inference.
recma-component-resolver: Dependency-graph analysis and selective component forwarding across nested MDX includes.
recma-static-refiner: Build-time prop extraction, schema validation, derivation, and pruning.
estree-util-to-static-value and object-graph-delta: Safe static evaluation and deterministic, cycle-safe structural diffing.
Tech Stack:
Frameworks: TypeScript · Next.js · React · MDX
Compiler tooling: Unified · Remark · Recma · MDAST · ESTree · ts-morph · esbuild
Competencies: Static analysis · AST traversal and transformation · dependency graphs · code generation · schema validation · route and bundle splitting
Tooling: Vitest · tsup · npm · performance benchmarking

Oliver Kirst
Last position:
Founder & AI Automation Architect at Zerobits
Zerobits is my vehicle for AI-powered automation and custom software development with a clear principle: AI solutions that reach production, not pilot stage. I design and build the systems myself - from first concept and architecture through implementation to deployment and operations.
My focus is on replacing repetitive, manual work with reliable automation and connecting disconnected tools and data sources into one dependable overall system.
Selected work:
- Design and implementation of LLM-based agent systems and RAG pipelines (Anthropic Claude, Mistral, MongoDB Atlas Vector Search + RAG)
- Workflow orchestration for long-running, fault-tolerant business processes using Temporal (temporal.io): saga patterns, event-driven architecture, retry and compensation logic, connecting third-party APIs and internal services into automated end-to-end processes
- Full stack product development: SaaS architecture on Kubernetes, TypeScript/React/NestJS, admin tooling with refine.dev and MUI
- AI-assisted development workflow as standard practice to deliver production software at a fraction of traditional timelines
- Full stack product development: multi-tenant SaaS architecture running on Kubernetes, backend with NestJS/Node.js and Python, frontend with TypeScript, React and Next.js, admin tooling with refine.dev and MUI, CI/CD with GitHub Actions
One of these projects is a product I own and operate - free of any NDA restrictions. I'm happy to demonstrate it end to end.

About the technology
React UI foundation
Material UI, also known as MUI, is a React component library for building consistent application interfaces. Teams use it for admin panels, customer portals, internal tools, and product front ends where speed and visual consistency matter. It gives specialists a ready base for layout, navigation, forms, and feedback states.
What specialists deliver
- Reusable component systems and page layouts
- Theme setup with colors, typography, spacing, and dark mode
- Form-heavy screens, tables, dialogs, and filters
- Accessibility-friendly patterns for keyboard and screen reader use
Strong professionals know how to keep the UI flexible without losing consistency. They work with the React stack around MUI and adapt the library to product and brand needs.
Core ecosystem
MUI work often includes React, TypeScript, Emotion or styled-components, and design tokens. Specialists also handle icon sets, routing, state management, and data-heavy components such as data grids or autocomplete fields. Good work fits the library into the wider frontend architecture instead of treating it as a visual layer only.
When to bring in help
Companies usually bring in freelance expertise when a product needs a new interface, a redesign, or a cleanup of inconsistent screens. It also helps when an in-house team must move fast, but still needs stable patterns for future features. In Germany, remote collaboration is common, while workshops and handover sessions can happen on-site when needed.
What good work looks like
A strong specialist understands component composition, theming, and the limits of prebuilt UI pieces. They write maintainable React code, keep the design system coherent, and prevent quick fixes from spreading through the app. They also know when to extend MUI and when to build a custom component.
Common project focus
- Design system rollouts and style alignment
- Refactoring legacy React screens to MUI
- Mobile-friendly enterprise interfaces
- Fast delivery of MVP front ends and feature modules
This work is common in SaaS, e-commerce, operations software, and customer self-service products. It suits teams that need practical front-end delivery, not just isolated visuals.
Frequently asked questions
Quick answers to the questions that come up most around Material UI.
Material UI is used to build React interfaces with consistent components, theming, and responsive layouts. Teams rely on it for dashboards, forms, navigation, tables, and other product screens that need to ship quickly without losing visual control.
Yes. MUI is the common short name for Material UI, and many specialists use both terms in profiles and project discussions. When you hire for this stack, searchers may use either name, so both should be clear in the brief.
Material UI is often chosen when a team wants a broad component set, a mature theming system, and strong support for business applications. Compared with lighter UI kits, it usually gives more structure; compared with fully custom systems, it saves more implementation time.
A strong Material UI specialist usually brings React, TypeScript, CSS fundamentals, and accessibility knowledge. Depending on the project, experience with design systems, Figma handoff, state management, and API integration also matters.
The right level depends on the scope, but Material UI work often needs someone who has shipped real React interfaces, not only tried the library in small demos. Simple page building is one thing; theme architecture, component reuse, and large screen sets need deeper experience.
Yes, most Material UI projects can be delivered remotely from Germany without issues. It helps when the specialist can review designs, join short feedback loops, and share working prototypes early. On-site sessions are useful for kickoff workshops or design alignment, but they are rarely required throughout the full project.
Look for clean React code, thoughtful theming, and interfaces that stay consistent across states and screen sizes. A good Material UI freelancer can explain component choices, accessibility decisions, and how the work fits your design system instead of only showing polished screenshots.
A good Material UI specialist will ask about the existing React stack, design tokens, browser support, and whether the team wants to extend MUI or stay close to the default components. Clear answers help avoid rework and make the handover smoother.
