Modernising old code without stopping the business

Verified provider · Development & IT · Expert · taking projects

A rewrite is a bet that the new thing is better, made all at once. We make it incrementally instead: the new system runs alongside the old, takes a slice of traffic, and the old one is only removed once the new one has proven itself in production.

What is included

  • A written assessment of what is worth keeping, rewriting or deleting.
  • Strangler-pattern migration so nothing is ever a big-bang cutover.
  • Characterisation tests around the existing behaviour before it is touched.
  • Explicit exit criteria for retiring each piece of the old system.

How the work runs

  1. Map the workflowWe break down your process and identify what an agent can own end-to-end.
  2. Design the agentModel selection, tool access, guardrails, on-chain permissions — designed with you.
  3. Build & simulateAgents tested in sandbox simulations; contracts rehearsed on testnets first.
  4. Deploy & monitorProduction launch with monitoring, alerting, and continuous improvement.
