Telecoms Integration Audit

A fixed-price, short engagement that turns a vague integration problem into a scoped, costed plan you can act on, with us or without us.

What you receive

  • A current-state map of your integrations with wholesale, porting and activation platforms
  • A risk and gap register covering order fallout, error handling, resilience and monitoring
  • A target approach and delivery sequence, with build, buy or partner recommendations
  • An effort estimate and a plan for the first release

Typical triggers: a new wholesale supplier or porting route, an order process that needs too much manual intervention, a stalled integration project, or a bid that depends on a credible technical plan.

Services

From first scoping to a working integration

The audit is the usual starting point. These are the ways we help once the plan is clear.

Supplier integration platforms

We design and build a single standard interface over several wholesale or mobile suppliers, using reusable components so each new supplier takes far less time to add. On one platform covering five suppliers, this cut onboarding from six months to three.

  • REST and SOAP supplier integrations behind one consistent API
  • .NET microservices, background job processing and resilient order handling
  • Container hosting on AWS or Azure, with testing and monitoring in place

SIM and MVNO automation

Services and portals that let mobile operators, MVNOs and connectivity resellers manage SIMs at scale, so customers set out what they want once and the platform carries out the actions.

  • Provisioning, barring, tariff changes and spend monitoring through network operator APIs
  • White-label React portals that can be sold as a product
  • Queue-based processing and billing system integration

AI-ready APIs

A fixed-scope package to expose your existing APIs to AI assistants and chatbots through a Model Context Protocol (MCP) server, with the same authentication and controls your APIs already use.

  • Review of which API operations suit AI use, and which do not
  • A working MCP server over your existing OAuth 2.0 secured APIs
  • Handover documentation for your own team

Delivery leadership

We take responsibility for getting an integration project to release: shaping the scope, leading a small team, coordinating suppliers and stakeholders, and keeping delivery on course.

  • Leading and mentoring small developer teams
  • Turning business requirements into tasks and release plans
  • Live incident handling and lessons learned
About

Senior engineering with a delivery background

Violet Willow Projects is led by Stephen, a senior software engineer who has spent his recent career on telecoms integrations: BT Wholesale ordering, broadband activation and number porting in the UK and France.

Earlier, he worked in local government as a regeneration manager. That experience of managing funded projects, partners and public accountability shapes how we run delivery today.
