Arc Internet

Rob West, Arc Internet Ltd

Senior engineer for awkward systems.

I am the engineer behind Arc Internet, based in Milton Keynes and working with clients across the UK: a practical systems specialist who can move from board-level business need to low-level technical detail without losing the thread.

That usually means bespoke software, systems integration, workflow automation, cloud infrastructure, data migration, network platforms, legacy systems and the awkward joins between them.

The short version

Arc Internet is deliberately small. You work directly with the person understanding the requirement, designing the architecture, building the system and helping it land inside the business.

When projects need ongoing cover, Arc Internet can also work with established support partners, giving customers a practical support route after delivery while keeping the senior technical relationship clear.

Established

Arc Internet Ltd has been solving awkward systems problems since 2010.

Scale

Designed ISP platforms for millions of users and billing systems handling millions per month.

Breadth

Works across software, infrastructure, networks, data, cloud, legacy systems and operations.

Delivery

One senior engineer from business requirement through architecture, build, integration and adoption.

Why that breadth matters

Many valuable projects do not live inside one tidy category. A customer portal might also need accounting data, Salesforce workflow, network provisioning, reporting and a migration from a spreadsheet that only one person understands.

My background is useful because I can follow the problem wherever it leads: from the business workflow, through architecture and code, into databases, cloud infrastructure, APIs, operating systems, networks and legacy systems that still matter.

Architecture and delivery

  • Enterprise and solutions architecture
  • Business analysis and true-requirement discovery
  • Agile delivery, test-driven development and fixed-price project scoping
  • Technical design authority, mentoring and cross-functional delivery

Software and integration

  • Bespoke business systems, admin portals and workflow applications
  • API development, systems integration and legacy modernisation
  • Salesforce, CRM, billing, ecommerce and finance-system integration
  • Python, PHP, C/C++, shell, Next.js, Dart and SQL-based systems

Cloud, data and infrastructure

  • AWS, Google Cloud, Terraform, Ansible and CI/CD automation
  • Relational SQL, Oracle, MySQL, Postgres, MongoDB and operational data migration
  • Linux and UNIX administration, low-level debugging and platform troubleshooting
  • Network automation, WAN, GPON, VPN, QoS and device integration

Modern AI-assisted practice

  • Practical agentic development with tools such as Codex, Gemini and Claude Code
  • AI-assisted automation where it genuinely improves a workflow
  • Senior review, testing and judgement around AI-generated implementation
  • Clear communication with business owners, operations teams and technical specialists

What I have worked on

Before and alongside Arc Internet, I have worked as an enterprise and solutions architect, technical design authority and senior developer across ISP infrastructure, global ecommerce, billing platforms, CRM integration, financial systems migration, data engineering, cloud provisioning and operational support systems.

That includes designing national broadband network systems, building authentication platforms for millions of internet users, creating telco billing systems, automating bare-metal and cloud provisioning, migrating global B2B billing data, and building Raildar, a real-time model of the UK rail network used by more than 100,000 people.

The common thread

The useful skill is not just knowing a long list of technologies. It is being able to understand a commercial problem, identify the real constraint, choose a sensible route through the technical layers and explain the trade-offs clearly to the people affected.

How I use modern tools

AI, automation and agentic development are now part of serious engineering work. I use them as leverage: to move faster, explore options, generate implementation paths and reduce routine effort.

The important part is still judgement. Someone has to understand the business context, review the architecture, test the result, protect the data, handle security and make sure the system can be supported after launch. That is where experience still earns its keep.
