Code that drives
business.
I'm Maksymilian Marcinowski — a Full-Stack Developer building modern websites, custom CMS, native mobile apps and AI-powered products. Enterprise-grade craft, freelancer pace.
What I build
End-to-end product engineering.
Discovery, design system, frontend, backend, infra and analytics — under one roof. You get a single point of accountability, not a Slack archeology project.
Web Platforms
Marketing sites, landing pages, multi-language portals. Lightning-fast, SEO-ready, conversion-tuned.
Custom CMS
No more WordPress lock-in. Headless, type-safe content systems shaped around your editorial flow.
AI Integrations
OpenAI, Claude, Hugging Face. Chatbots, automation, search and content pipelines wired into your product.
Product MVPs
From Figma to production in weeks. Auth, payments, dashboards — engineered to scale past launch.
Behind the keyboard
// hi, I'm Max
Six years deep in production code. I'm an independent freelance full-stack developer working under the MaxCode Studio name — so you work directly with the person building it and get senior-engineer output without the agency middle layer.
I've shipped SaaS platforms, native iOS & Android apps, custom CMS, AI-powered tooling and high-converting marketing sites for clients across PL, DK and the EU. I care about clean architecture, measurable outcomes, and honest deadlines.

Selected work
KSR Cranes
Operations platform for a Danish crane-operator rental: marketing site, internal dashboard, and two native mobile apps (iOS + Android) for dispatch, timesheets and project tracking.
Cupside
Cross-platform Flutter mobile app with a matching marketing site — end-to-end product design, frontend, and backend integrations.
MM Dust
Marketing and lead-gen website for a Danish industrial cleaning company — fast, SEO-tuned, fully responsive.

Marketing site for an insurance broker — compare prices and coverage, with an EN/PL bilingual UI, fast and fully responsive.
More under NDA
Custom dashboards, AI integrations and product MVPs shipped for clients across PL, DK and the EU. Details on request.
How I ship
Discovery
30-min call. I map the goal, constraints and what 'done' looks like — written, not assumed.
Blueprint
Fixed scope, fixed timeline. Architecture, design tokens and a shipping plan you can show your team.
Build
Weekly demos in your own preview environment. No black-box agencies, no surprise invoices.
Ship & iterate
Deploy, monitor, measure. I stay on retainer or hand off clean code — your call.
The stack
Pragmatic over trendy. I pick boring, battle-tested tools where they fit — and reach for the bleeding edge only when it gives your users a real edge.
Got an idea?
Let's ship it.
