Custom IT systems · CRM · Security

IT systems built from zero.
Shaped by your business — not a template.

01

End to end

From discovery to maintenance — one team, full accountability.

02

Security-first

Code and architecture are reviewed at every stage, not after the fact.

03

Built to fit

Architecture follows your processes, never the other way round.

Our approach

Most companies don't need another off-the-shelf application. They need a system that works the way they do.

We design every system from the ground up — around the processes, requirements and way of working of one specific organisation. No compromises imposed by packaged software, and no features you pay for but never use.

Work

Case study · Our own product

A CRM for temporary work agencies, built from scratch.

A system for agencies and employers hiring foreign workers. Instead of spreadsheets and binders: workers with documents and expiry alerts, residence and work permit cases, recruitment on configurable workflows, and the Polish 18-in-36-months temporary work limit calculated automatically. Runs in the cloud or on the client's own server.

CRM dashboard in dark mode: the user's tasks, legalization cases with deadlines and workforce statistics
The dashboard shows what is waiting for your role: recruitments, cases with deadlines, expiring documents.
01

Workers and documents

Passports, visas, residence cards, medical exams and safety training with expiry alerts on the dashboard and in a daily e-mail.

02

Foreign worker permits

Cases moving through stages, default deadlines (e.g. a 7-day notification), fees and attachments.

03

18/36-month limit

Time at each client is tracked automatically on every assignment, with a warning before the limit is crossed.

04

Configurable

Custom fields and formulas, role-based workflows, Excel import and export of lists to Excel.

05

Security

2FA, database-level data isolation (Row-Level Security), sensitivity labels with identity re-confirmation.

06

GDPR built in

Consents with history, retention periods, personal data export and anonymization. A full audit log.

Where you start

You don't have to rebuild everything.

01 — You have a system

We'll analyse, secure and extend what you already have.

If you already run a system, website or application, we start with an honest assessment of where it stands — then fix what's broken and take it further.

  1. Analyse→
  2. Verify→
  3. Secure→
  4. Improve→
  5. Evolve

02 — You have an idea

We'll take you from concept to a working product.

If you're still planning, we run the entire process: from gathering requirements, through architecture and design, to production deployment.

    Discovery

    We learn your processes, people and goals, then define scope and success criteria.

    We design the system structure, data model and integrations with scale in mind.

  3. 03

    Design

    Interfaces and flows shaped around how your team actually works.

    Maintenance, support and extension as your business grows.

Engagement

From focused assignments to multi-phase implementations.

01

Defined-scope assignments

A clear goal and timeline — an audit, an integration, a new feature or a fix to an existing solution.

02

Phased programmes

Larger systems delivered in stages, with a measurable result and a review point after each phase.

Principles

We don't sell templates.

01

From zero

Every system is built from the ground up — no templates, no imposed limitations.

02

Process-led

Software mirrors how your company operates instead of forcing it to change.

03

Secure by default

Code and architecture review is part of the process, not an add-on.

04

Partnership

We stay after launch — maintaining, supporting and evolving the system.

Contact

Have a process that could be automated? Let's talk.

A system that needs rebuilding, an idea that off-the-shelf software can't handle well, or a need for an independent audit — describe the challenge briefly and we'll come back with proposed next steps.
