Software for the
{operational} edge
of real businesses.
I'm Jakub Rekowski — fullstack developer, solution architect, devops engineer and graphic designer working under the ReqLynx Digitalworks banner. I build production systems for events, transit, venues, e-commerce, and the people who run them.
Four roles, {one operator}.
Most of my projects don't fit cleanly into one job description, so I don't pretend they do. The same person who scopes the architecture writes the migrations, ships the deploy pipeline, and designs the marketing site.
Fullstack
development
End-to-end product work in TypeScript. NextJS, NestJS and Hono on the server side; React, React Native and Svelte on the client.
Solution
architecture
Mapping a business problem to a system. Domain decomposition, data modelling, integration boundaries, sane migration paths.
Devops &
infrastructure
CI/CD pipelines, container orchestration, observability and the unglamorous infrastructure that keeps shipped products shipped.
Graphic
design
Brand systems, marks, marketing surfaces and the application UI that wears them. The lynx mark to your left is house work.
Tools {I reach for}.
Things I've {shipped}.
Ten production systems across events, transit, hospitality and corporate web. Each card opens a writeup with the brief, the architecture and the trade-offs.

I prefer to {own} the outcome.
The work I'm proudest of started as a single conversation about a real operational pain — a frantic spreadsheet, a 3 AM invoice run, a dispatcher Frankenstacking five vendor tools — and ended as a system the team uses every day without thinking about it.
I'm comfortable owning a project from architecture through deployment, and equally comfortable plugging into an existing team where you need a senior pair of hands. ReqLynx Digitalworks is the studio name; the work is mine.
Have something {operational}
that needs building?
The shortest path from your problem to a working system is a 30-minute conversation. Tell me what's on fire.
