About Us

Software development with operations in mind

We build business software, platforms and AI features that do not end at the MVP. Portals, dashboards, APIs, automation and internal tools are designed to run reliably in day-to-day operations.

AI-ready architecture
Our specialization is infrastructure-adjacent software: remote site management, IoT, tenant platforms, RAG, agents and systems where code, data, network and operations have to be designed together.
Maintainable systems
That does not exclude classical software development. On the contrary: UX, frontend, backend, data models and integrations are the foundation. The difference is that we include deployment, security, monitoring and maintenance from the start.
Fast iteration
Short feedback cycles; AI-assisted development speeds things up, production code stays reviewed and tested.
Sovereign operations
Operation on local or European infrastructure, deployment and monitoring included.

Services

Focus areas for production software

From new platforms and integrations to modernisation and ongoing maintenance - code, data, interfaces and operations are planned together.

Portals · dashboards · APIs
We need our own platform or business software
Auth stacks, resource-level permissions and audit trails for B2B SaaS and member management, custom dashboards and ETL pipelines, internal tools in TypeScript, Go and Python, REST/GraphQL/gRPC APIs with ERP/CRM/EDI integration.
Industry · critical infrastructure · retrofit
We run distributed sites, plants or devices
Multi-tenant platforms with WireGuard-orchestrated VPN tunnelling and browser remote access, edge agents and OPC UA/Modbus/MQTT gateways for Industry 4.0, OT remote maintenance without open ports as a sovereign Ewon/IXON alternative.
RAG · agents · LLM
We want to use AI features in production
RAG systems, internal AI assistants, agents and LLM integrations - built as secure, maintainable and operable software.
Existing software · maintenance
Our software has grown and is hard to maintain
Containerisation, the strangler fig pattern and a planned cutover and rollback. Then dependency and CVE maintenance, technical fixes, controlled releases and plannable further development.

Development Process

From use case to operations

We do not plan software separately from deployment, security and maintenance. Especially with AI features and infrastructure-adjacent platforms, this connection decides whether the system works in production.

01
Use case & system context
We clarify goals, users, data sources, risks and operating environment. This shows early whether the project is classical software, AI features, infrastructure automation or a combination. Deliverables: Target picture & system context · Risk, data and integration analysis · Roadmap & prioritization
02
Architecture & UX
We design software architecture, data model, integrations and user flows together with the operating model. For AI features, access, evaluation and guardrails are planned from the start. Deliverables: System architecture & data model · UI/UX flows & prototypes · Security and operations concept
03
Development
We build in clear iterations with short feedback cycles. AI-assisted development helps us move faster, but production code remains reviewed, tested and traceable. Deliverables: MVP or feature increment · APIs, integrations and data flows · Code reviews and automated tests
04
Testing, security & AI evaluation
We test functionality, performance, security and usability. For AI features, test sets, tracing and quality metrics are added so behavior is not judged only subjectively. Deliverables: Automated test runs · Security and performance checks · AI evaluation where relevant
05
Deployment & operations
We deploy the application into the target environment and set up CI/CD, monitoring, backups, secrets and runbooks. Operations are part of the release, not an afterthought. Deliverables: Production Deployment · CI/CD, monitoring and alerting · Backup, rollback and runbook concept
06
Maintenance & evolution
After go-live, updates, CVE monitoring, small changes and larger extensions stay plannable. Project software does not become an unmanaged risk. Deliverables: Operations support & incident response · Patches, updates and CVE monitoring · Feature Extensions

Platform showcase

Four platform types we know inside out

Instead of starting from zero each time, we combine proven architecture patterns. You gain months of time-to-market and avoid the classical traps - fragile auth, missing audit trails, unclear AI quality or unpredictable scaling decisions.

Remote Management Platforms

One central console for distributed industrial and critical-infrastructure sites. Secure browser access, granular permissions per tenant and plant, full audit trail.

Secure, automated site connectivity
Browser access to VNC and web HMIs without client plugin
Audit-grade logs including impersonation workflows
Multi-region and multi-tenant scaling

Learn more about the platform

Member & Tenant Platforms

Platforms for member admin, B2B portals, and internal operator consoles. Robust auth stack, multi-level permissions, complete audit logs, and misuse protection.

Robust auth stack with single sign-on and soft delete
Multi-level permissions, optionally multi-factor
Audit trails including support impersonation
Encrypted secrets, deep tenant isolation

Learn more about the platform

Data Platforms & Custom Dashboards

Tailored dashboards for real-time data - IoT sensors, plant telemetry, monitoring aggregation. When off-the-shelf tools like Grafana hit their limit, we build the visualization layer ourselves with focus on UX and domain workflows.

Smooth real-time visualization even with thousands of data sources
Robust data pipelines that absorb load spikes
Export, reporting, and drill-down workflows
Integration with IoT hub and managed-operations monitoring

Learn more about the platform

AI Software & Agents

Add AI features directly into existing portals, dashboards and internal tools. With RAG, tool use, access control, tracing and an operations concept instead of an isolated chatbot demo.

RAG with sources, roles and data updates
Agents with controlled tool use
Evaluation, tracing and quality control
Operations on local or European infrastructure

Case Study

Production References: nextGYM & ABCO Water Systems

Two platforms in production use for centrally managing, deploying and remotely accessing distributed environments and industrial sites.

Deployment Time: 3-4h → 5 Min; nextGYM
Audit-grade remote HMI access: VPN client → Browser tab; ABCO Water Systems · AB-View

nextGYM - Remote Management and One-Click Deployment for Distributed IoT Environments
For nextGYM GmbH, we built a platform to remotely manage and deploy distributed IoT environments. Through a central dashboard, nextGYM rolls out new sites via one-click deployment - cutting the rollout per studio from 3-4 hours to 5 minutes. Each unmanned location runs as an isolated environment with fine-grained permissions (RBAC), individual firewall policies and Mesh-VPN on a WireGuard basis with profile management. An integrated template system and router monitoring via OpenWrt for centralized traffic statistics (IoT SIM cards) complete the platform and let the company scale faster.
ABCO Water Systems - AB-View: Remote Access to Distributed Industrial Sites
With AB-View, we built a platform in production use for browser-based remote access to distributed industrial sites. Operators access the HMI interfaces of their sites directly in the browser without local VPN clients - via Apache Guacamole and WireGuard, multi-tenant and with a traceable audit trail.

Software projects with reliable outcomes

Proof for modernization, API extension, architecture, deployment and ongoing operations.

WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
