ZirkelTech modernizes applications, databases, and integration landscapes that slow growth and accumulate risk. We work incrementally: legacy systems are wrapped, re-platformed, and decomposed - without the effort of a full replacement program and without operational disruption.
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.h.

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.

Re-architect custom ABAP programs, user exits, and enhancement spots into clean-core BTP extensions using ABAP RAP for on-stack logic and CAP Node.js for side-by-side services. Business logic preserved, FIORI Elements UIs delivered, core upgrade cycle fully decoupled.

Modernise .NET Framework 4.x and Java EE 7 to .NET 8 and Spring Boot 3 on Azure Container Apps or AKS. Azure Migrate assessment, Docker multi-stage containerisation, Key Vault secret injection, and Application Insights distributed tracing without code-level instrumentation changes.

Structured data migration from legacy ERP platforms (SAP ECC, Navision, Infor, Sage) to S/4HANA or Business Central using LTMC, BODS, or custom ETL tooling. Full data profiling, cleansing, reconciliation, mock cutover rehearsals, and go-live hyper-care support with rollback playbooks.

Replace outdated SAP GUI screens, WinForms, and Delphi desktop interfaces with responsive web frontends built on React or Angular, consuming existing backend logic via newly exposed REST APIs. Users gain modern UX without disrupting underlying business logic or requiring a full system replacement.

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.

The ZirkelTech team was instrumental in developing our Personal Finance platform - MoolahMate. Their expertise ensured a seamless integration with another solution provider while also incorporating robust security. They met all the deadlines, responded to our queries quickly and stayed within budget. Their ability to listen, suggest ideas, dedication and professionalism make them an invaluable partner. It has been a pleasure to work with them as a partner in our journey to deliver a great solution for our customers.
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.
