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, a freelance studio, and a workflow built around Next.js, automation, Linux, 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 for recruiter candy. These are truthful snapshots of the kind of systems I build and operate.
A live freelance site that combines custom design, service positioning, blog content, contact conversion, and an embedded AI assistant.

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.

Proof angle: Real client-style service site focused on clarity and enquiries rather than design-dribbble theatre.
A self-hosted assistant workflow using Hermes Agent, OpenRouter, Telegram delivery, persistent memory, cron jobs, and server-side tooling.

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. Novel concept, apparently.
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.
Good fit signals

AI-native development, internal tools, automation, support engineering, web platforms, infra-adjacent roles
Small teams where “I can figure it out and ship it” matters more than ceremony cosplay
Fintech/Web3 contexts where automation, APIs, security habits, and crypto-native literacy help
Not pretending to be

If you need someone who can build, automate, debug, and explain the system, talk to me.
Send the role, the messy requirement, or the thing your team keeps doing manually. I will tell you directly if I am a fit. Dangerous concept: honesty.
