SOFTWARE ENGINEERING · APIs · QUALITY

Maintain, extend and integrate your existing applications.

We help when software changes take too long, integrations fail or feature backlogs build up. We agree the problem and acceptance criteria, then deliver improvements in manageable steps. Technical software engineering is in English, with Finnish-speaking client coordination by agreement.

SOFTWARE ENGINEERING

When an existing application needs attention.

In this fictional example, recurring application defects are investigated and an agreed fix and new feature are developed incrementally, reviewed and tested.

These examples are fictional and do not represent completed client projects.

SOFTWARE DEVELOPMENT · INTEGRATIONS · TESTING

Solving the software problems that slow teams down.

When an existing application is hard to change, integrations create manual work or releases introduce recurring defects, we help diagnose the issue and deliver defined improvements. We can work on a scoped project or alongside your development team.

THE CHALLENGE

Existing applications are hard to maintain

Changes take too long, defects keep returning and technical debt consumes internal development capacity.

OUR APPROACH

We examine the existing code, identify root causes and deliver focused fixes or enhancements without assuming a full rewrite is necessary.

THE GOAL

More maintainable software and more predictable changes.

THE CHALLENGE

Systems do not exchange data reliably

Manual transfers and unreliable APIs interrupt business workflows.

OUR APPROACH

We build or improve APIs, backend services and integrations, with agreed error handling, testing and documentation.

THE GOAL

Less manual handoff and more reliable data flow.

THE CHALLENGE

Feature backlogs keep growing

Your team needs development capacity for frontend, backend or unfinished application features.

OUR APPROACH

We take ownership of defined tasks within your existing backlog, contributing code through your team's review and delivery practices.

THE GOAL

Progress on priority features without unnecessary replacement work.

THE CHALLENGE

Testing slows every release

Manual checks take time and regressions are hard to reproduce or detect.

OUR APPROACH

We design test cases, reproduce and document defects, check APIs and automate repeatable tests where appropriate.

THE GOAL

Clearer release evidence and better control over quality.

AGILE COLLABORATION

Clear scope. Visible progress. Tested changes.

We agree on the problem and acceptance criteria before building. We can contribute to a client's agile delivery process or take responsibility for a defined project without insisting on a full platform rewrite.

Discuss a project
  1. Understand what exists

    Review the system, dependencies, priorities and acceptance criteria.

  2. Work in manageable increments

    Implement agreed changes, share progress and follow the client's code review and delivery practices.

  3. Test and hand over

    Verify functionality, record results and agree on documentation and follow-up support.

Project-based full-stack engineering

Application development & integrations

Maintenance and enhancements for existing applications, frontend changes, Node.js and .NET backend services, and REST API integrations. Technical delivery is in English; Finnish client coordination can be arranged.

Technical working language for software engineering: English. Specialist availability is confirmed per assignment.

Testing, data & Microsoft 365

Functional QA, test cases, regression and API checks, Power BI reporting, Excel, SQL/Python and Microsoft 365 workflows.

Testing, reporting, documentation and project coordination are available in Finnish and English. Software engineering is delivered by an agreed specialist.

The tools support the work

Technology choices depend on the existing system and the customer's needs. We do not recommend a new stack merely because it appears on a skills list.

TypeScript · JavaScript · Node.js · React · Angular · Vue.js · C# / .NET · REST APIs · Next.js · Azure Functions · Kafka · Docker

These are examples of problems we can help evaluate, not claims that Komplyint Oy has delivered the featured external customer cases. We confirm availability, scope, technology and language before engagement.

Services and delivery approach

Download our brochure covering common software challenges, engineering delivery, quality assurance and working languages.

01

Maintainable applications

Understand existing code, diagnose recurring bugs and implement agreed enhancements without an unnecessary complete rewrite.

02

APIs and system integrations

Improve data exchange, backend services, error handling, testing and integration documentation.

03

Frontend and backend features

Deliver defined tasks in the client’s backlog, following their reviews and engineering practices.

04

Testing within development

Functional QA, test cases, API and regression checks, and suitable automation before release.

Agree delivery responsibilities first

The specialist, technical language, scope, testing and support responsibilities are confirmed before engagement. Critical-system standby and security certification are outside the standard service.

PRODUCT DEVELOPMENT

Our software products

We also develop our own digital products. We keep this work separate from client projects so responsibilities and timelines remain clear.
