Websites.
Apps.
Things that work.

I'm Sean — an IT technician who builds software to solve problems I see in everyday work. I've been creating laboratory dashboards, sample trackers and document tools, and I build websites and practical apps for other businesses too.

01 / Application interface previews

A closer look
at what I build.

These previews follow the navigation, layout and visual approach of my actual application projects. Explore the interfaces using fictional sample data. The private, backend-connected development applications are not exposed to visitors.

Interactive UI previews   The LabGuard and LabSphere previews reproduce visible design patterns from the original frontends; the remaining three are simplified workflow concepts. All use fictional data and are isolated from workplace systems. No adoption, approval or accreditation is implied.

02 / Selected development projects

Built from problems I've seen first-hand.

These are self-initiated software projects that I'm developing, including some I've proposed as ways to improve workplace processes. They're not presented as paid client work or systems already adopted by an employer.

PROJECT / 01Illustration — no live records
Read-only analyticsLabGuard

LabGuard — a clearer view of lab data.

Developing an analytics interface over existing laboratory data, including sample search, form views, analysis evidence and readiness checks without writing back to the source LIMS.

PROJECT / 02Illustration — no client screens
Lab operationsLabSphere

LabSphere — bringing operations together.

Building an integrated laboratory-management platform with modules for equipment, quality, operational workflows and controlled records. It's a development project, not a certified system.

PROJECT / 03Illustration — sample workflow
Sample trackingSampleFlow

SampleFlow — making progress visible.

Exploring interactive boards for receiving, preparation, analysis and review so teams can see where a sample is and what action comes next.

PROJECT / 04Illustration — generic forms
Document managementWorkflow controls

Document Control — less manual chasing.

Developing a document and recurring-forms concept with assigned responsibilities, due dates, reviews and a searchable record history. Still under development.

Project visuals are illustrative. The public interactive demos use synthetic data and separately written code, not internal datasets, employer documents or proprietary application source.

02 / Services

03 / Behind RatioTech

I'm Sean.
I solve tech problems.

“If there's a simpler, reliable way to do it, that's the way I want to build it.”

My background is in the hands-on side of IT: supporting users, managing systems, working with networks and finding fixes when things go wrong. It's made me think carefully about the people who have to use the software, not just the people who build it.

RatioTech is where I bring that experience together with web development, application building and automation. I use established development tools and AI-assisted coding when it helps, but I still care about the basics: understanding the problem, testing and making the result maintainable.

I'm interested in projects that take an everyday frustration and make it easier to deal with.

How I work

Keep it practical.

01

Understand

Find out what needs to change before choosing the technology.

02

Build & review

Make something useful, test it and improve what doesn't work.

03

Hand over & support

Make sure people know how to use it and maintain it.
