Integrations & APIs
Connect business systems and make data move reliably between them.
- REST, SOAP and API design
- Frends iPaaS and C#/.NET development
- Dynamics 365, Business Central and SAP integrations
- Testing, error handling and production delivery
Let's get your
software working.
Systems that need to connect. A workflow that needs to be simpler. An idea ready to become a product. I bring architecture and implementation together, and work directly with the people who own the problem.
100+ client integrations delivered across my career.
Helsinki and remote. Scope and availability agreed before work begins.
Where I can
help.
I focus on work where understanding the wider system matters as much as writing the code.
Web & Mobile Products
Build a focused business website or take a web or mobile product from idea to release.
- React, Next.js and TypeScript
- Flutter mobile applications
- Backend, authentication and database integration
- Deployment and App Store release support
Automation & AI Integration
Reduce repetitive work and add AI features where they solve a clear problem.
- Business process and API automation
- LLM API integration and structured outputs
- Retrieval-augmented applications
- Practical reliability, cost and data boundaries
Less theory.
More things you can open.
TM Beauty is a client website. KovaFit and DartScope are independent apps. These public projects sit alongside my enterprise integration experience.
A straightforward
way to work.
Start with the problem. Agree what a useful result looks like. Keep the decisions and the delivery close together.
Understand the problem
Review your current systems, constraints and the outcome you need.
Agree the delivery
Define scope, responsibilities, milestones and acceptance criteria.
Build, test and hand over
Implement the solution, review it together and document how to run it.
