Performed a comparative benchmark of telemetry collection options, focusing on resource footprint and compatibility for an OpenTelemetry-based architecture. Migrated observability from a fragmented stack (logs/metrics/traces) to a unified OpenTelemetry pipeline routed into Dynatrace. Deployed the solution on Kubernetes using Helm and coordinated deployment via ArgoCD GitOps. Built Dynatrace dashboards and configured anomaly-detection alerts for API security and reliability.

Test Automation Frameworks

2/10

Building automated tests

Minimal test automation presence: test runners and frameworks declared but no real fixtures, factories, mock servers, parallelization or selector discipline in code.

Evidence

ci-cd-pipeline-with-jenkins/Cookingapp-main/package.json - devDependencies include karma and jasmine

ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/src/test/java/com/example/cookingapp/CookingappApplicationTests.java - placeholder Spring Boot test class

Test Coverage & Strategy

1/10

What and how to test

No visible test coverage strategy or meaningful negative/boundary tests; only test script entries and a placeholder test class exist.

Evidence

ci-cd-pipeline-with-jenkins/Cookingapp-main/package.json - "test" script

ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/src/test/java/com/example/cookingapp/CookingappApplicationTests.java - lacks assertions or test cases

API & Integration Testing

1/10

Testing how parts work together

APIs and repositories are implemented but there are no integration or contract tests, schema validation, or idempotency/retry test coverage.

Evidence

ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/Controller/ItemController.java - controller present but no API tests

ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/Repositories/Recieperepo.java - repository with queries but no contract tests

Recommendations

Add focused unit and integration test suites: write Spring MVC controller tests and repository tests, then instrument end-to-end API contract tests (for example with schemathesis or contract tests) to validate error paths and schema invariants.
Introduce Testcontainers for integration tests against a real MySQL/MariaDB instance and add per-test data isolation and cleanup to make API tests reliable.
Build frontend unit/e2e tests that avoid sleep-based waits: convert to conditional waits, add selector discipline (data-testid) and meaningful negative/boundary assertions for edge cases.
Create CI pipelines that capture test artifacts (reports, logs, screenshots), implement test sharding or selective runs, and add quarantine rules for flaky tests rather than global retries.

Repositories

The developer's experience in this domain has been verified based on AI analysis of the following repositories:

ci-cd-pipeline-with-jenkins Miniproject

Junior Backend Developer Confidence: Medium API Engineer

Full-stack developer working with Java Spring Boot backends and Angular frontends at a junior level with a strength in building straightforward REST-backed web applications. The strongest proven skill is implementing Spring Boot REST endpoints and JPA-backed entities as evidenced by Controller and Repository classes such as Controller/ItemController.java and Repositories/Itemrepo.java. There is limited evidence of production-grade concerns such as schema migrations, authentication and authorization, resilience patterns, performance tuning, or comprehensive observability.

API Design

2/10

How well APIs are designed

Basic REST endpoints and client API usage exist but there is no versioning, idempotency, pagination strategy or consistent error contract; controllers are simple CRUD-style handlers.

Evidence

Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/Controller/ItemController.java Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/Controller/ReceipeController.java Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-main/Cookingapp-main/src/app/api.service.ts

Data Layer & Database

2/10

Working with databases

JPA entity classes and Spring Data repositories are present showing basic ORM use, but there is no migration history, explicit transaction boundaries, or tuned queries/indexes.

Evidence

Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/Model/RecipesEntity.java Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/Model/ItemEntity.java Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/Repositories/Itemrepo.java

Scalability & Performance

Handling load and speed

Not evidenced in public code

System Architecture

2/10

Overall system structure

Monolithic Spring Boot backend paired with an Angular frontend shows reasonable folder separation, but there is no evidence of deliberate service decomposition, config/secret management, or graceful degradation strategies.

Evidence

Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/CookingappApplication.java Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/WebConfig.java

Top-level package layout under src/main/java/com/example/cookingapp

Security & Auth

1/10

Protecting data and access

Minimal security posture is evident; there is basic CORS configuration and some client-side input checks but no authentication/authorization flows, token lifecycle, input validation at the API boundary, or secrets hygiene.

Evidence

Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/Cookingapp-cookappbackend/src/main/java/com/example/cookingapp/WebConfig.java Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-main/Cookingapp-main/src/app/budget/budget.component.ts

Reliability & Observability

1/10

Stability and monitoring

Very limited reliability and observability practices; frontend console logging and a placeholder unit test exist but there are no structured logs, metrics, retries with backoff, timeouts, circuit breakers or graceful shutdown handling.

Evidence

Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-main/Cookingapp-main/src/app/budget/budget.component.ts (console.log usage) Sarralabidi/ci-cd-pipeline-with-jenkins/Cookingapp-cookappbackend/Cookingapp-cookappbackend/src/test/java/com/example/cookingapp/CookingappApplicationTests.java

Expand testing and reliability work with integration tests, retries/timeouts where appropriate, and CI/CD pipelines for automated builds and deploys

Repositories

The developer's experience in this domain has been verified based on AI analysis of the following repositories:

ci-cd-pipeline-with-jenkins Miniproject

Junior DevOps Engineer Confidence: Medium Platform SRE

Platform SRE at a Middle level specializing in Kubernetes-based observability and Helm-driven deployments. The strongest proven skill is Kubernetes operational hardening and telemetry integration as shown by observability-platform/apim-deployment.yaml and apps/wso2mi-chart/mi/values_full.yaml. There is little public evidence of advanced pipeline engineering, Terraform-style IaC with remote state, infra testing or incident runbooks and postmortems.

CI/CD Pipelines

2/10

Automated build and deploy

Basic CI pipeline present using GitHub Actions for lint and image build but no advanced pipeline engineering patterns such as matrices, reusable workflows, gated deploys, caching keys or artifact promotion.

Evidence

Miniproject/.github/workflows/ci.yml: simple steps for checkout, setup-python, flake8 linting and docker build

Infrastructure as Code

3/10

Managing servers with code

Helm values and rendered manifests exist showing environment separation and secret integrations but this is largely chart/values configuration rather than custom modular IaC with state management, tests or migrations.

Evidence

observability-platform/apps/wso2mi-chart/mi/values_full.yaml: provider/aws/azure/gcp secretManager and vault/hashicorp sections; HPA, pdb and storage settings

observability-platform/apim-deployment.yaml: rendered Deployment objects and use of secretKeyRef for DB credentials

Containerization & Orchestration

4/10

Working with containers

Concrete Kubernetes orchestration decisions are present including tuned startup/liveness/readiness probes, resource requests/limits, non-root securityContext, preStop lifecycle and podAntiAffinity which show practical k8s operational knowledge.

Evidence

observability-platform/apim-deployment.yaml: tuned startupProbe, liveness/readiness probes, resources and securityContext for wso2am and wso2mi containers

observability-platform/apps/wso2mi-chart/mi/values_full.yaml: deployment.strategy, pdb/hpa and probe configuration parameters

Observability & Monitoring

4/10

Watching system health

Observability integration is explicit with OpenTelemetry configuration and an otel sidecar declared alongside application containers indicating awareness of telemetry pipelines and vendor token provisioning.

Evidence

observability-platform/apps/wso2mi-chart/mi/values_full.yaml: opentelemetry section including url and type set to otlp

observability-platform/apim-deployment.yaml: otel-sidecar container and environment variables referencing DT_API_TOKEN and DT_TENANT_URL

Reliability & Incident Response

3/10

Keeping systems up

Reliability-oriented settings such as preStop hooks, graceful termination, anti-affinity and rolling update/replica controls are present but there are no runbooks, incident postmortems, chaos experiments or explicit rollback gates.

Evidence

observability-platform/apim-deployment.yaml: lifecycle.preStop hook and terminationGracePeriodSeconds for wso2am container

observability-platform/apim-deployment.yaml: affinity podAntiAffinity and strategy.rollingUpdate settings

Cloud & Cost Optimization

2/10

Smart use of the cloud

Some cloud-related and cost-aware knobs exist (resource requests/limits, HPA config placeholder, EFS/Filestore options and secret manager integrations) but there is no evidence of active cost optimization, spot/eviction strategies or measured rightsizing.

Evidence

observability-platform/apps/wso2mi-chart/mi/values_full.yaml: aws/azure/gcp storage and secret manager sections and hpa/pdb configuration

observability-platform/apim-deployment.yaml: resources.requests and limits defined for containers

Recommendations

Develop robust CI/CD promotion pipelines with gated deploy steps, reusable workflows and caching to move beyond simple lint-and-build pipelines.
Build and publish Helm-based environment modules and add automated infra tests (conftest/terratest) and remote state discipline for IaC.
Create SLOs, alerting rules and runbooks tied to service telemetry and implement automated rollback/gating strategies for releases.
Audit and eliminate image:latest usage and strengthen image provenance (pin digests and add signing) for production sidecars and collectors.
