Audit
Override Audit
Two weeks. Repo ingested, intents mapped, a rewrite roadmap you can take to the board — whether or not you hire us.
- Full codebase + infra read
- Risk & intent map
- 90-day rewrite plan

Rewrite
your legacy.
Don't rebuild it.
We overwrite COBOL, PHP 5, jQuery spaghetti and forgotten monoliths with AI-native systems — in weeks, not years. No big-bang migrations. No consultant theatre.

what we do
We overwrite systems that were never going to make it.
Override Technologies is a small crew of engineers using AI as leverage — not as a demo. We read your codebase, map the dependency graph, and rewrite it module by module into something your team can actually ship on top of.
Read
Read the legacy
Static analysis, runtime tracing, and an LLM-assisted map of every intent still living in the code — including the ones nobody documented.
Specify
Specify the override
We produce a rewrite spec that reads like product docs, not a 400-page architecture PDF. Your team signs off line by line.
Rewrite
Rewrite, module by module
Strangler-fig pattern, AI-accelerated. Each module ships behind a feature flag and replaces its ancestor without a cutover weekend.
Handover
Hand back the keys
We leave you a codebase your juniors can own, runbooks your SREs trust, and a deprecation plan for the last legacy byte.
how it works
Four phases. No cutover weekends.
Audit
Intake / Audit
Two weeks. We ingest the repo, interview the people who still remember why it exists, and return a risk map.

We wrap the legacy with an override gateway. Every request is observable. Nothing moves until it's safe.

Rewrite
Rewrite
Modules are rewritten against a golden test set. AI drafts, senior engineers ship. Nothing merges without behaviour parity.
- legacy/* · + core/*
Decom
Decommission
Traffic shifts behind flags. When utilisation hits zero, the old system is archived, not maintained.
- legacy/
services
Four engagement models.
Rewrite
Module Rewrite
Pick a module that's hurting. We rewrite it against your existing contracts and hand it back running in production behind a flag.
- Strangler-fig deployment
- Golden test set
- Zero-downtime cutover
Full override
Full Override
End-to-end modernization of a legacy stack. We embed, rewrite module by module, decommission the old system, and hand the keys to your team.
- Embedded senior crew
- Monthly decommission targets
- Full handover & runbooks
Off-cloud
Cloud Exit
We measure what you actually run, price it against bare metal (Hetzner, Latitude.sh, OVH) and move it workload by workload, with the hyperscaler account live until nothing needs it.
- Per-workload cutover, reversible
- Egress + managed services, priced first
- Documented before/after bill
