Services

The full refactoring catalog.

CodeWave operates as an integrated engineering practice — every service below is delivered by the same senior pods, against the same disciplines, with the same audit-grade output. We do not subcontract, we do not staff-augment, and we do not chase scope. What follows is the work we do, end-to-end, every day.

01

Microservices Refactoring

We decompose monolithic codebases into bounded-context services using domain-driven design — without halting feature delivery.

  • Domain decomposition workshops with your engineering leadership
  • Strangler-fig extraction of high-friction subdomains first
  • Anti-corruption layers preserving legacy contracts during transition
  • Service ownership models with on-call rotations and SLOs from day one
02

API Management & Governance

We design, document, and govern the API surface that will outlive your current architecture — internal, partner, and public tiers alike.

  • OpenAPI 3.1 and gRPC contracts with breaking-change CI gates
  • Federated GraphQL BFF layers for product and mobile teams
  • Gateway selection, rate-limit policy, and quota economics
  • Developer portals with SDK generation and contract test suites
03

Legacy Migration & Mainframe Modernization

From COBOL and Delphi to z/OS and PowerBuilder, we migrate the systems that other firms refuse to touch — under live production load.

  • Automated code archaeology and dead-code elimination
  • Behavioral baselining via traffic shadowing and log mining
  • Parallel-run reconciliation with diff-based validation
  • Reversible cutovers within a single deployment window
04

Cloud-Native Platform Engineering

We build the internal developer platform on which your new architecture lives — Kubernetes, GitOps, observability, security baked in.

  • Multi-cluster Kubernetes with progressive delivery via ArgoCD
  • OpenTelemetry-first observability across services and data planes
  • Workload identity with SPIFFE/SPIRE and policy-as-code via OPA
  • Cost-aware multi-cloud or sovereign-cloud architectures
05

Event-Driven Architecture & Streaming

We re-platform batch-driven systems onto event-driven backbones, turning nightly reconciliation jobs into millisecond reactions.

  • Kafka and Pulsar topology design for regulated workloads
  • Change-data-capture pipelines with Debezium and Iceberg
  • Exactly-once semantics for financial and inventory domains
  • Schema-registry governance and consumer-driven contracts
06

Code Assessment & Architecture Audits

Before a single line is refactored, we tell you the truth about what you have, what it costs, and what to do about it.

  • Static and dynamic analysis with cyclomatic and coupling metrics
  • Architectural-fitness function scoring against your roadmap
  • Regulator-ready risk register and remediation prioritization
  • Written architecture decision records you actually own
Engagement model

A four-phase rhythm we have run hundreds of times.

Every engagement follows the same disciplined cadence, regardless of size. Phases are sequential but iterative — we revisit earlier phases whenever the production system tells us something new. Nothing is hidden behind statements of work; the artifacts and decisions of each phase are visible to every stakeholder in real time.

Phase 01

Discovery & Baseline

Two to four weeks of code archaeology, traffic shadowing, and stakeholder interviews. Output: a behavioral baseline and refactoring tier.

Phase 02

Architecture & Decomposition

Domain-driven decomposition workshops, target architecture, and the first slice of strangler-fig extraction scoped.

Phase 03

Iterative Refactoring

Service-by-service extraction under parallel-run validation, with continuous reconciliation against the legacy baseline.

Phase 04

Cutover & Handover

Final traffic shift, legacy dark-launch, and a documented handover that leaves your team in full ownership of what we built.
