Yhteenveto

I have long experience in the SW development industry from various domain and roles. Last years I have been
working as an architect and SW developer specifying, designing, implementing, deploying, and testing IoT-solutions:
- Implemented backend services for both Azure and GCP in C#, JavaScript and Go using .NET/NET Core and Node.js.
- Implemented multiple frontend applications for both Azure and GCP in JavaScript using React and Redux.
- Using databases like Cosmos DB, MongoDB, MySQL and MSSQL.
- Created and deployed Docker images to Kubernetes clusters running in GCP.
- Developed IoT gateways in C#, Go, C and Python running in Linux.
- Implemented pipelines in Azure DevOps for automatic build and deployment of SW components to cloud.
- Designed, implemented and secured REST API interfaces and using OpenAPI for API specification.
- Developed one Android application using React Native.

I have also very strong experience in multiple areas like team leadership, project management, product management, program management and technology management from international top technology companies, Nokia, and Microsoft, hence I can provide additional strengths beyond technical skills and competencies.

I am looking for positions where my curiosity to solve customers' problems with a team can be leveraged when developing new innovations providing true business value and at the same time having fun.

Core Competencies and Skills

My most important skills are the abilities to understand and solve customer problems. This requires good communication skills, analytical thinking, good understanding how a solution can be built in a cost-efficient way and ability to implement, test, and deliver the solution. I am curious by nature and love learning new things. Working with challenging tasks with a good team are key motivators for me, being very persistent is helping to solve complex problems.
