Software, That Enables Business Models

ZirkelTech builds the engineering capabilities that sit beneath and alongside your enterprise platforms. Custom applications, cloud infrastructure, data pipelines, and AI systems. We work where off-the-shelf software ends and real technical complexity begins with production-grade results without unnecessary abstraction.

OUR CAPABILITIES
Engineering with Impact.

Engineering the software, data, and cloud foundations that keep your business moving faster than the market.

01

Full-Stack Application Development - Web & Mobile

Custom web applications with React 18, Next.js, and TypeScript, cross-platform mobile apps with React Native or Flutter, and B2B portals with role-based access via Azure AD B2C - built to replace Excel-driven processes and extend enterprise platforms with purpose-built interfaces.

#React #Nextjs #TypeScript #ReactNative #Flutter #AzureADB2C #Playwright

02

Backend API Engineering & Microservice Architecture

Scalable REST and GraphQL APIs with Node.js Fastify, .NET 8, or Spring Boot 3. OpenAPI contract-first design, OAuth 2.0 authentication, and event-driven microservice patterns using Apache Kafka and Azure Service Bus - independently deployable, load-tested, and observable from day one.

#Nodejs #DotNet8 #SpringBoot3 #OpenAPI #ApacheKafka #AzureServiceBus #k6

03

Cloud Infrastructure & Kubernetes Platform Engineering

Production-ready cloud infrastructure on Azure and AWS: modular Terraform and Azure Bicep, AKS and EKS with Workload Identity and KEDA autoscaling, Istio Service Mesh and Argo CD GitOps delivery - with policy enforcement and compliance scanning in every CI pipeline.

#Terraform #AzureBicep #AKS #EKS #ArgoCD #Istio #KEDA #Kyverno #Checkov

04

CI/CD, DevSecOps & Software Delivery Pipelines

End-to-end delivery pipelines with GitHub Actions and Azure DevOps multi-stage YAML. SAST, container scanning, SBOM generation, and supply chain attestation - security embedded at every stage, not bolted on after the fact.

#GitHubActions #AzureDevOps #OIDC #SonarQube #Trivy #Cosign #Syft #SBOM #DevSecOps

05

Lakehouse & Data Platform Engineering

Modern ELT data platforms on Databricks Delta Lake or Snowflake: Bronze/Silver/Gold medallion architecture, Delta Live Tables for streaming and batch pipelines, dbt transformation layers with column-level lineage, Great Expectations quality gates, and Unity Catalog for governed cross-workspace data access.

#Databricks #DeltaLake #Snowflake #dbtCore #DeltaLiveTables #UnityCatalog #GreatExpectations

06

AI & Machine Learning Systems

Production-ready AI on Azure OpenAI and Databricks Mosaic AI: RAG pipelines on enterprise data, multi-agent orchestration with LangGraph and CrewAI, MLflow Model Registry with drift detection, and LLM fine-tuning on GPU clusters.

#AzureOpenAI #DatabricksMosaicAI #LangGraph #CrewAI #MLflow #EvidentlyAI #DBRX #Llama3

07

Legacy Modernisation & System Re-platforming

Incremental modernization of monolithic Java EE, .NET Framework, COBOL, and AS/400 systems: Strangler Fig decomposition, API facades via MuleSoft or Azure APIM, database migrations, and ABAP legacy re-architected into clean-core BTP extensions with RAP and CAP.

#.NET Framework >.NET 8 #Java EE >Spring Boot #COBOL > Cloud-native #SAP RAP/CAP #MuleSoft #Azure APIM

08

Observability, Cloud Security & Software Quality

OpenTelemetry instrumentation with Datadog APM and Grafana LGTM, SLO burn rate alerting, and continuous profiling. Zero-trust security posture via Microsoft Defender for Cloud and Sentinel. Shift-left quality with Vitest, Playwright, Pact contract testing, and FinOps governance.

#OpenTelemetry #Datadog #GrafanaLGTM #MicrosoftSentinel #ZeroTrust #Kubecost #Vitest #Playwright #Pact

09

Dedicated Engineering Teams & Capacity Extension

Long-term integrated development teams for .NET, React, Python, and cloud engineering — not freelancers on call, but colleagues with product knowledge who work to your standards and in your repositories. Onboarding into your domain, your codebase, and your processes so collaboration is productive from the first sprint. Scalable development capacity without the fixed costs and recruitment risks of building an internal team.
