Incrementally modernising grown Java EE, .NET Framework, COBOL, and AS/400 systems - without operational disruption and without big-bang risk. Strangler fig decomposition, API facades, database migrations, and clean-core re-architecture. We systematically resolve technical debt so your legacy systems stop blocking innovation and start enabling it.
Incremental modernization - from assessment through architecture to cloud migration.
Incrementally extract bounded contexts from monolithic Java EE and .NET Framework applications into microservices on AKS or EKS. Domain seams defined via event storming, async messaging via Apache Kafka, and traffic routed through API gateways with Istio service mesh.

Expose COBOL, AS/400 RPG, and legacy SOAP/EDI interfaces as governed REST and GraphQL APIs without touching the core. MuleSoft or Azure APIM façades, Avro/JSON Schema data contracts, and an internal API Marketplace with consumption SLAs for downstream teams.

Schema conversion and data migration from Oracle 11g/12c and IBM DB2 to Azure SQL Managed Instance, SAP HANA, or PostgreSQL using AWS SCT and Azure DMS. Stored procedure validation, unsupported T-SQL remediation, and zero-downtime cutover via CDC replication.

Migrate fragile Informatica and SSIS pipelines to a modern ELT Lakehouse on Databricks Delta Lake or Azure Synapse. dbt transformation layers with column-level lineage, Great Expectations data quality gates, and SSRS reports replaced by Power BI semantic models.

Structured discovery and assessment of legacy application landscapes: CAST Highlight or SonarQube codebase analysis, dependency mapping, cloud readiness scoring, and total cost of ownership modelling. Output is a prioritised, phased modernisation roadmap with effort estimates, risk ratings, and recommended target architecture per system.

30% Efficiency GainWe chose ZirkelTech because we needed a strategic partner with world-class expertise to work alongside our multi-national SAP S/4 team. We found ZirkelTech to be the most flexible, well-organized and trustworthy. We highly appreciate not just the subject matter knowledge, but also the enthusiasm and readiness consistently shown by the colleagues to discuss and try out novel approaches to solving complex problems.
Our employees needed real-time assistance at all times. Equally important to us were feedback on work steps, intuitive usability, flexible application, and a solution that could be deployed at short notice. We achieved all of these goals with ZirkelTech and trust the new solution for digitizing our shopfloor processes.
ZirkelTech has supported us from the idea of a collaboration platform to its final marketability with high competence and reliability. Thanks to the partnership and agile cooperation, the idea was quickly transformed into a proof of concept. ZirkelTech continues to be our strategic partner for future projects, due to its commitment and flexibility.

Also, for future projects ZirkelTech is the first choice for us.
DLC GmbH has experienced a significant boost in efficiency and project management thanks to the exceptional technical solutions provided by Zirkel Tech. Their team’s technical expertise, prompt response times, and unwavering dedication to our unique needs have been invaluable. We highly recommend their reliable and professional services to any business seeking top-notch IT support. Zirkel Tech has truly become an integral part of our success.
ZirkelTech was instrumental in building our Personal Finance platform, MoolahMate. They delivered seamless integration with another solution provider, robust security, and stayed on time and on budget. Their ability to listen, suggest ideas, and their professionalism make them an invaluable partner. A pleasure to work with.
From the very first discovery workshop, the ZirkelTech team demonstrated a rare combination of deep technical knowledge and genuine curiosity about our manufacturing operations. Rather than proposing a generic off-the-shelf solution, they invested heavily in understanding our specific OEE (Overall Equipment Effectiveness) measurement methodology, our rejection-tracking workflows, and our compliance obligations under IATF 16949. This groundwork paid dividends throughout the entire project.
