Corexel

Service boundaries and APIs designed for evolution under load.

API & Microservices

REST, GraphQL, and event-driven microservices with versioning, auth, and developer experience.

Engagement snapshot

Service boundaries that survive organizational change.

We define failure modes, versioning, and deprecation paths before traffic — so integrations do not become permanent tech debt.

Contract-first

OpenAPI / schema gates in CI

Capability plane

Service boundaries and APIs designed for evolution under load.

Scoped with explicit boundaries, operational readiness, and engineering ownership through handoff.

Overview

What we deliver

We decompose monoliths and design new services around domain boundaries — not arbitrary technical splits. API gateways, rate limiting, schema versioning, and contract tests keep integrators productive as services evolve.

Deliverables

  • Service boundary map and context diagram
  • OpenAPI/GraphQL specifications
  • AuthN/AuthZ model (OAuth2, JWT, mTLS as needed)
  • Contract tests and consumer-driven compatibility

Process

How we run the engagement

  1. 01

    Product discovery

    User journeys, domain rules, and non-functional requirements captured with stakeholders before wireframes or sprints.

  2. 02

    Application architecture

    Module boundaries, data model, auth model, and deployment topology documented with explicit trade-offs.

  3. 03

    Iterative delivery

    Feature increments with automated tests, performance budgets, and demo-ready acceptance criteria each sprint.

  4. 04

    Launch & operate

    Production cutover, monitoring dashboards, and handoff to your product and platform teams.
