I build the content layer technical products scale on.

Schemas and content models for technical product companies — built to survive the third page type, and clean enough for AI agents to generate from. Hackathon mentor on the side.

SELECT * FROM identity

Maciej Trzciński is a content infrastructure engineer based in Poznań, Poland, working remotely with technical product companies worldwide. He designs the schemas, content models, and CMS architecture that products publish on — typically in TypeScript, React, and Next.js with Sanity, Vercel, and Supabase — and migrates teams to headless CMS in-flight, without a content freeze. He also mentors hackathon teams on scope-cutting and rapid prototyping.

The Toolkit

A content infrastructure engineer designs the schemas, content models, and CMS architecture a technical product publishes on — the layer beneath the content, built so new page types scale without a rebuild and structured data stays correct for both search engines and AI agents.

Content Infrastructure

Schemas, content models, and the CMS architecture beneath them. Structured so new page types scale without a rebuild — and so structured data stays correct across every surface.

0→1 Product Engineering

Greenfield Next.js. Stack picked from the product's actual constraints — TypeScript, React, Sanity, Vercel, Supabase. Owned end-to-end when solo, contract-bound when in a team.

Design Systems & Architecture

Reusable TypeScript/React component libraries documented in Storybook. Stack selection, state-management patterns, contract design, data-layer migrations. The boring foundations multiple product surfaces sit on.

Rules

The product lens — how I think about building content infrastructure, greenfield or already in flight.

prop: "Stack_From_Constraints"

A stack should fit the product's actual shape — content types, who edits, who consumes. Picked from constraints, not from a house template.

prop: "Model_First"

Schemas decide whether a site scales. A model that bends on the third page type is the one you rebuild in year two — design it before the first screen lands.

prop: "Beyond_The_Demo"

Content stacks live with real authors, real edge cases, and real scale — not the live demo. The boring foundations are what ship the product.

prop: "Year_Three_Default"

Production code is a longer game than a demo. What ships in week one is what runs in year three. Build for the year-three version.
