Production web apps
Next.js, Tailwind, TypeScript, performance-focused UI, SEO fundamentals, contact flows, analytics, and real deployment plumbing.
Recruiter portfolio, built for skim-reading, not archaeology
I build web apps, automations, and AI-assisted systems that actually run.
I am Mateusz Reglinski, a web developer with Microsoft server-infrastructure experience, running an independent freelance studio with a workflow built around Next.js, automation, and practical AI agents.

AI-assisted delivery
I use Claude Code, Codex, Hermes, MCP workflows, and structured reviews to ship faster without turning the codebase into soup.
Automation systems
n8n workflows, lead handling, reporting, CRM-style glue, email flows, scraping where legal, and small internal tools that remove repetitive work.
Server infrastructure
Linux, Docker, Dokploy, Traefik, Cloudflare, Tailscale, hardened VPS setups, monitoring basics, and pragmatic production ops.
case snapshots
The shape of work I can deliver.
Not everything can be public, and I am not going to invent fake metrics. These are truthful snapshots of the kind of systems I build and operate.

Proof angle: You are looking at it. The site is the product, not a screenshot pretending to be one.
A clean local-business website for a handyman service with service pages, fast browsing, mobile-first layout, and direct enquiry paths.

A public MCP-style tool around Polish public-business data workflows: useful for agentic due diligence, verification, and structured company lookups.

Proof angle: Practical automation for repetitive admin work: capture the input, transform it cleanly, route it to the right place, and leave an audit trail.
workflow
How I work when the brief is messy.
I am useful in the gap between “we need something” and “there is a working system people can use”. That gap is usually where projects go to quietly die.
01
Map the problem
I turn fuzzy requirements into a visible workflow: users, inputs, outputs, edge cases, risks, and what can be shipped first.
02
Build the useful slice
I prefer small working releases over huge hidden rewrites. Web page, dashboard, API route, agent tool, automation; whatever proves the value fastest.
03
Verify with real output
Builds, linting, screenshots, logs, test fixtures, working links. If it was not exercised, it is not done.
04
Harden and explain it
I document how it works, what it does not do, where secrets live, and how someone else can safely operate it later.
