01 — Technology consulting & engineering

Systems that hold steady as your business moves.

HERJU Consulting GmbH helps organisations decide what to build, then designs and delivers the software, cloud platforms and data flows behind it.

02 — Introduction

An independent IT consultancy that stays involved from the first diagram to the running system.

We combine advisory work with hands-on engineering. That means the people who recommend an architecture are also able to build it, and the people who build it understand why it was chosen.

Our work covers strategy, custom software, cloud and infrastructure, security, and data automation. Engagements can be short and focused or run across several phases.

03 — Core IT capabilities

Six disciplines, one connected practice.

  1. 01

    IT strategy

    Roadmaps, technology choices and architecture reviews tied to business priorities.

  2. 02

    Software engineering

    Web applications, APIs and internal tools built for long-term maintainability.

  3. 03

    Cloud & infrastructure

    Platform design, migration planning, automation and cost awareness.

  4. 04

    Systems integration

    Connecting existing applications through clear interfaces and reliable data exchange.

  5. 05

    Cybersecurity

    Risk-based assessments, secure design and practical hardening guidance.

  6. 06

    Data & automation

    Pipelines, reporting foundations and automation of repetitive workflows.

04 — IT strategy and consulting

Decisions first. Technology second.

Before recommending tools, we map what the business needs to achieve, which constraints are real, and where existing systems help or hold you back. The output is a written set of options with trade-offs, not a single answer presented as inevitable.

05 — Custom software engineering

Software written to be read, changed and run.

We build web applications, APIs, back-office tools and integrations. Each project starts with a thin, working slice that reaches a real environment early, so feedback is based on running software rather than slides.

  • → Domain modelling with the people who know the process
  • → Automated tests at the levels that matter
  • → Code review on every change
  • → Documentation kept next to the code

06 — Cloud and infrastructure

Platforms described in code, sized for actual load.

We design and review cloud environments, plan migrations in stages, and express infrastructure as code so it can be reviewed, versioned and rebuilt. Monitoring, backups and access control are treated as part of the platform, not afterthoughts.

Where on-premises or hybrid setups make more sense, we say so.

07 — Cybersecurity approach

Security as layered, ordinary practice.

We start from the assets that matter most and the realistic ways they could be exposed. Recommendations are ranked by risk reduction and effort, so teams can act on them in order rather than face an undifferentiated list.

  • Least-privilege identity and access
  • Secrets kept out of code
  • Dependency and patch hygiene
  • Logging that supports investigation

08 — Data and automation

Fewer spreadsheets passed by hand.

We build pipelines that move data between systems with validation at each step, and automate recurring tasks that currently depend on manual copying. Reporting is built on documented, shared definitions so numbers mean the same thing everywhere.

09 — Delivery methodology

Short cycles, visible progress, explicit decisions.

  1. Phase 1

    Discover

    Interviews, system walkthroughs and a shared problem statement.

  2. Phase 2

    Frame

    Scope, success criteria, risks and a first-phase plan in writing.

  3. Phase 3

    Build

    Iterations of one to two weeks with working increments.

  4. Phase 4

    Verify

    Testing, review and acceptance against agreed criteria.

  5. Phase 5

    Hand over

    Documentation, runbooks and knowledge transfer sessions.

10 — Collaboration principles

We work with your team, not around it.

One shared backlog
Priorities are visible to everyone and changed openly.
Plain-language updates
Regular written summaries of progress, risks and decisions needed.
Knowledge stays with you
Pairing and documentation so expertise does not leave when we do.
Disagreement is useful
We state concerns early and record the reasoning behind choices.

11 — Quality and engineering practices

The unglamorous habits that keep systems healthy.

Version control for everything

Application code, infrastructure definitions and configuration live in repositories with history.

Automated pipelines

Builds, tests and deployments run the same way every time.

Reviewable changes

Small pull requests with context make review meaningful.

Observability

Logs, metrics and alerts designed around how the system actually fails.

Decision records

Short notes explaining why an approach was chosen and what was rejected.

Accessible interfaces

User interfaces checked for keyboard use, contrast and readable structure.

12 — Frequently asked questions

Straight answers.

What kind of organisations do you work with?

We work with companies that rely on software and infrastructure to run their business and want an outside team to help plan, build or improve those systems. The size of the organisation matters less than having a clear owner on the client side.

Can you join a project that is already underway?

Yes. We usually start with a short review of the code, infrastructure and open decisions so we understand the current state before proposing changes or taking on tasks.

Do you only work with a specific technology stack?

No. We recommend technologies based on your context, existing skills and long-term maintenance needs rather than a fixed preference. Where an existing stack is working, we generally build on it.

Who owns the code and documentation you produce?

Ownership terms are agreed in the project contract before work begins. Our working default is that deliverables are handed over in your repositories and accounts so your team retains full access.

How do engagements usually start?

With an email describing your situation. From there we arrange a conversation to clarify goals and constraints, then propose a scope, approach and first phase in writing.

Do you provide ongoing support after delivery?

Support arrangements can be agreed as part of an engagement. We also prepare handover material so your own team can operate and extend what was built.
