Services

What we do,
and how we do it.

A working list of the disciplines Nice & Simple GmbH covers. Most engagements combine several of them; almost none require all. Each service is delivered by the same senior team, with the same standards.

Service 01

Custom Software Development

What it includes: Discovery, product architecture, engineering, testing, deployment, and long-term maintenance of custom applications built to the specific needs of a business.
The problem it addresses: Off-the-shelf software rarely fits the exact shape of the operations it is meant to support. We build the software that does.
Delivery approach: Small senior teams working in short, reviewable increments alongside the client, with visible artefacts each week and no hidden work.
Technical considerations: Language, framework, and platform choices are made from the constraints of the problem. We are comfortable across TypeScript, Python, Go, Java, and .NET, and we favour boring, well-supported technologies.

Service 02

Web Application Development

What it includes: Design and implementation of customer-facing and internal web applications, including accessibility, performance, and search visibility as first-class concerns.
The problem it addresses: Web applications sit closest to the people who use them. A slow, awkward, or fragile interface is felt every day.
Delivery approach: Interface design, component systems, front-end engineering, and integration with back-end services, delivered as one continuous track rather than a hand-off between disciplines.
Technical considerations: Modern component frameworks, server rendering where it helps performance and SEO, progressive enhancement where users cannot rely on JavaScript.

Service 03

Backend Development

What it includes: Design and implementation of the services, data models, and workflows that stand behind an application — the layer that has to remain correct under load.
The problem it addresses: Most product risk lives in the back-end. Data integrity, transactional behaviour, and evolving business rules quietly determine how much a system can be trusted.
Delivery approach: Clean domain modelling, explicit boundaries between services, automated tests around behaviours that matter, and observable interfaces from the first release.
Technical considerations: Relational and document stores, message brokers, background workers, and the tooling required to reason about system behaviour after it is deployed.

Service 04

Frontend Development

What it includes: Interface implementation with attention to accessibility, keyboard interaction, colour contrast, motion preferences, and predictable performance across devices.
The problem it addresses: A front-end that is not built with care is difficult to change. Every future feature costs more than it should, and every user pays a small tax each session.
Delivery approach: Design tokens, shared component libraries, typed data contracts with the back-end, and disciplined attention to bundle size and rendering behaviour.
Technical considerations: Component-based frameworks, static and server rendering, CSS design systems, and web platform features used in preference to heavy libraries where possible.

Service 05

API Development & Integration

What it includes: Design and implementation of new APIs, as well as integration between existing systems, whether internal services, third-party platforms, or partner interfaces.
The problem it addresses: As organisations grow, the space between systems becomes the hardest part of the estate. Integration debt compounds silently.
Delivery approach: Contract-first design, explicit versioning, sensible authentication, and end-to-end tests that describe how the systems are expected to behave together.
Technical considerations: REST, GraphQL, event-driven interfaces, and webhook patterns, selected for the shape of the data and the operational needs of both sides.

Service 06

Cloud Infrastructure

What it includes: Design, implementation, and operation of cloud environments — networking, compute, storage, identity, and delivery pipelines described as code.
The problem it addresses: Cloud environments that grew by accident become expensive, fragile, and difficult to reason about. New engineers cannot find their way in.
Delivery approach: Infrastructure as code, environment parity, well-defined boundaries between accounts and workloads, and a clear operating model for the client's team.
Technical considerations: AWS, Google Cloud, Azure, and self-hosted platforms, along with the container, serverless, and orchestration tooling appropriate to each.

Service 07

IT Consulting

What it includes: Architectural review, technology strategy, technical due diligence, and pragmatic advice on the trade-offs that matter for a specific business.
The problem it addresses: Technology decisions taken without a second view are difficult to reverse. A short, well-scoped engagement can prevent large downstream costs.
Delivery approach: Short engagements with a defined artefact: a written assessment, a decision record, a roadmap, or a targeted proof of concept.
Technical considerations: Vendor-neutral analysis of platforms, languages, patterns, and vendors, informed by hands-on engineering experience rather than presentation slides.

Service 08

System Modernisation

What it includes: Careful modernisation of systems that have outgrown their original design, without discarding the business knowledge encoded in them.
The problem it addresses: Legacy systems are not old — they are load-bearing. A rewrite that ignores that fact usually replaces one set of problems with a worse set.
Delivery approach: Incremental migration paths, strangler patterns, parallel runs, and reversible steps, with the client's operations remaining stable throughout.
Technical considerations: Interop between existing runtimes and new services, database migration strategies, and the observability required to compare old and new behaviour.

Service 09

Cybersecurity Consulting

What it includes: Security review of applications and infrastructure, threat modelling, remediation planning, and support for the operational practices that keep systems defensible.
The problem it addresses: Security failures are usually design failures with delayed consequences. It is far cheaper to correct them before they are exploited than after.
Delivery approach: Structured review of authentication, authorisation, data handling, secrets management, dependency posture, and incident readiness, with prioritised remediation.
Technical considerations: OWASP-aligned assessment, cryptography choices appropriate to the data, and hardening of cloud, network, and identity layers.

Service 10

Data Solutions

What it includes: Design of data pipelines, storage layers, and analytical systems that turn operational data into information the business can act on.
The problem it addresses: Data that cannot be trusted is worse than no data at all. Reliability, lineage, and governance are what make analytics useful.
Delivery approach: Sensible schemas, well-documented pipelines, monitoring of data quality, and access patterns that respect both privacy and utility.
Technical considerations: Batch and streaming pipelines, warehouses, lakehouses, and analytics tooling chosen for the volume, shape, and sensitivity of the data.

Service 11

Quality Assurance

What it includes: Test strategy, automation, exploratory testing, and the review practices that catch regressions before they reach users.
The problem it addresses: Quality is not tested into a product at the end. It is built in throughout, or it is absent throughout.
Delivery approach: Layered testing — unit, integration, and end-to-end — proportional to the risk of each area, with fast feedback in the delivery pipeline.
Technical considerations: Language-native test frameworks, browser and API automation tools, contract testing, and observability data used to guide test coverage.

Service 12

Technical Support & Maintenance

What it includes: Continued care of systems after initial delivery — small changes, dependency updates, monitoring, incident response, and quiet operational work.
The problem it addresses: Software that is not maintained decays. The most expensive systems are the ones nobody has touched in a year and now nobody wants to.
Delivery approach: Predictable maintenance cadences, clear runbooks, on-call arrangements agreed in writing, and steady, undramatic upkeep.
Technical considerations: Monitoring and alerting appropriate to the system, dependency management, and the operational discipline required to keep a running system boring.
