SERVICES

Services

End-to-end development for stable systems

  • API Design & Spring Boot

    API-First (OpenAPI/Swagger), versioning, clear contracts — fast to integrate, easy to maintain

    • OpenAPI/Swagger contracts & versioning, client generation
    • Ports & adapters (hexagonal), clear service boundaries
    • Tests (unit/contract/integration), quality gates & performance checks
    • Spec-driven with spectant, implementation accelerated by AI coding agents

  • Web & Frontend

    Angular, TypeScript, NGRX/NGXS — performant UIs with clean API integration and solid state management

    • Angular (standalone components, OnPush, SSR), clean component architecture
    • State management with NGRX/NGXS, reactive data pipelines with RxJS
    • Responsive layouts, accessibility, performance optimization (lazy loading, bundle splitting)

  • Microservices & Events

    Bounded contexts, Kafka/RabbitMQ, resilience (idempotency, retries) — robust scaling without chaos

    • Domain decomposition & bounded contexts, clear responsibilities
    • Events & messaging (Kafka/RabbitMQ), idempotency & retry strategies
    • Resilience patterns: circuit breaker, timeouts, exponential backoff, dead-letter queues

  • Delivery & Operations

    Docker, Kubernetes, Helm, GitLab CI/CD, blue/green & canary — predictable releases, secure operations

    • GitLab CI/CD: build & release pipelines, artifact versioning & promotions
    • Kubernetes/Helm deployments, blue/green & canary rollouts (optional GitOps)
    • Observability hooks (metrics, logs, traces), SLOs & alerts

  • Databases & Storage

    PostgreSQL/MariaDB/MongoDB — reliable data foundation, high performance

    • Schema design & migration (Flyway/Liquibase), consistency & versioning
    • Tuning & scaling: indexing, EXPLAIN, connection pooling, replication/HA
    • Backup & restore (PITR), disaster recovery

  • Observability & Search

    Elasticsearch, Kibana, Superset, metrics/logs/traces — transparency, dashboards & fast root cause analysis

    • Self-service dashboards (Kibana, Superset), clear KPI sets
    • Low-maintenance data models, consistent definitions, traceable metrics
    • OpenTelemetry/structured logs, distributed tracing

  • AI Workflows & Automation

    Ollama, n8n — local AI workflows & automation

    • Local LLM models with Ollama for internal workflows
    • n8n-based automations and integrations
    • Data pipelines and intelligent process optimization

  • AI Agent Coding & Spec-driven Development

    Coding agents working from clear specs — ship faster without giving up control of architecture and quality

    • Spec-driven development with spectant: spec, plan and tasks before the first line of code
    • Agents implement against the spec, every task closed with verifiable evidence
    • Review, tests and quality gates stay in human hands
