Our expertise

One partner, six connected areas of expertise.

Modern software rarely stands alone. We approach users, processes, data, integrations, security and maintenance as one system—creating a solution that works today and grows tomorrow.

01 — Custom software development

When off-the-shelf software slows processes or limits ambition, we create a solution that fits: modular, maintainable and designed for real users. From internal business software and client portals to SaaS products, we turn complex processes into secure and intuitive digital environments.

Process gains. Automate recurring work, reduce handover errors and make status immediately visible.

Control of growth. A modular architecture expands without turning every next step into a rebuild.

Ownership. Clear documentation, transferable code and agreements that prevent lock-in.

  • Business analysis and requirements
  • UX/UI and interactive prototype
  • Secure front end and back end
  • Automated testing and quality control
  • Production setup and monitoring
  • Maintenance and continuous development

When is custom software the right choice?
When a process differentiates your business, standard products create excessive manual work, or integration and scale are critical. Discovery also compares custom work with realistic alternatives.

How does the budget stay manageable?
We prioritise business value, start with an MVP where appropriate and deliver in short iterations so assumptions are tested early.

Can you take over existing software?
Yes. We begin with a technical and functional assessment before targeted improvement, staged modernisation or replacement.

02 — Web applications & platforms

We build responsive web applications, client portals and corporate platforms that combine speed, accessibility, security and conversion. The browser becomes a powerful workplace: no installation, available on every device and connected to the systems you already use.

Easy to use. Clear flows and interfaces reduce friction and accelerate tasks.

Discoverable & fast. Technical SEO, semantic content and strong Core Web Vitals from the foundation.

Securely connected. Authentication, roles and integrations use least privilege and clear data flows.

  • Customer and employee portals
  • Progressive Web Apps
  • Corporate websites and platforms
  • Headless or custom CMS
  • Multilingual and accessible delivery
  • Hosting, monitoring and support

What is the difference between a website and a web application?
A website primarily informs; a web application supports interactive processes, accounts, data and workflows. Many modern platforms combine both.

Can you work with our existing CMS?
Yes. We first assess technology, security and maintainability, then recommend improvement, a headless extension or controlled migration.

Will the solution be accessible?
We design and test keyboard use, contrast, semantics and understandable interaction, using WCAG as a practical baseline.

03 — Mobile app development

We develop intuitive mobile apps for iOS and Android, native or cross-platform, connected to a reliable back end. A strong app feels natural, performs under changing conditions and is designed for updates and growth from day one.

One clear experience. Flows fit mobile behaviour while remaining recognisable across platforms.

Sound technology choice. Native, cross-platform or PWA follows usage, integration needs and total ownership cost.

Ready to operate. Release processes, logging and analytics keep quality measurable after launch.

  • Concept and product strategy
  • Mobile UX/UI and prototype
  • iOS and Android engineering
  • API and cloud back end
  • App Store and Play Store guidance
  • Monitoring and continuous development

Native or cross-platform?
The answer depends on performance, device features, budget and roadmap. We document the choice before development.

Can you build an MVP?
Yes. We define the smallest version that creates real value and learning while keeping the architecture ready for logical expansion.

Do you support store publication?
Yes. We guide signing, store content, privacy information, testing and submission to Apple and Google.

04 — API & system integrations

We connect software, data and processes through secure APIs and automation: reliable, observable and resilient to change. From an accounting connection to an integration landscape, we make data flows visible, reduce errors and design for recovery.

Less duplicate work. Data is captured in the right place and transferred with validation.

Reliable data. Validation, idempotency and audit logs make failures visible and recoverable.

Secure access. Tokens, secrets, scopes and personal data follow the principle of least privilege.

  • API and data mapping
  • REST, GraphQL and webhooks
  • Microsoft Graph and Microsoft 365
  • CRM, ERP and accounting connections
  • Monitoring, retries and audit logs
  • Technical documentation

Can legacy systems be connected?
Often. We examine APIs, exports, databases and security boundaries and select an adapter or phased exposure strategy.

How do you prevent duplicate or lost data?
Through unique keys, idempotent processing, queues where useful, validation, retry mechanisms and observable logging.

Who maintains the integration?
Your team can take over with documentation, or ELDIKIT can provide monitoring and a maintenance agreement.

05 — Practical AI implementation

We combine opportunity, data, risk and cost to build AI features that measurably help, with human control where it matters. Not a disconnected chatbot because it is fashionable, but a considered application for knowledge, documents, employees or smarter workflows.

Value first. Use cases are tested for time, quality, risk and feasibility before scaling.

Data under control. Access, retention and sensitive information are explicitly designed.

Measurable behaviour. Evaluations, guardrails and logging make quality and cost visible.

  • AI use-case discovery
  • Proof of concept and evaluation set
  • RAG and knowledge assistants
  • Document and workflow automation
  • Model and API integrations
  • Governance, monitoring and cost controls

Is our data ready for AI?
We assess quality, structure, sensitivity and availability. A small evaluation set quickly reveals where preparation is needed.

How do you limit generative AI errors?
With clear task boundaries, source grounding, controlled context, automated evaluations and human approval for impactful decisions.

Must we choose a single AI provider?
Not always. Where useful we design an abstraction so model choice can follow quality, privacy, speed and cost.

06 — Maintain & grow

We monitor health, security and performance and improve according to usage, feedback and changing needs. From technical debt to continuous product development, we create clarity, reduce risk and build a realistic roadmap.

Continuity. Monitoring, backups and incident agreements reduce downtime and surprises.

Secure and current. Dependencies, configuration and vulnerabilities remain controlled.

Focused growth. Data and feedback determine which improvements add the most value.

  • Technical audit and baseline
  • Monitoring and incident response
  • Security and dependency updates
  • Performance and Core Web Vitals
  • Backup and recovery checks
  • Roadmap and iterative development

Can you take over existing software?
Yes, after a controlled handover and risk assessment covering code, infrastructure, access, documentation and known issues.

Do you offer service levels?
Where appropriate, availability, priorities, response times and responsibilities are defined in a maintenance or SLA agreement.

Can maintenance and development run together?
Yes. A stable maintenance baseline prevents innovation from being overtaken by technical debt.
