Platform Rewrite AccelerationPlatform Rewrite Acceleration
Modernize Your Legacy Platform Without Stalling The Roadmap
Keep requirements, migration, and quality moving as fast as the code, with NuStack’s AI-DLC pods in your rewrite.
The Problem
AI coding agents have made code the fast part of a rewrite. The delays now come from everything around it, and that is where modernization programs slip.
Requirements
Turning years of product behavior into specs an agent can build is slow, and it takes domain experts.
Migration
Your customers need a safe path off the old platform, with the tooling, test workbooks, and cutover plan to carry them across.
Parity
Before anyone trusts an agent-built product in production, it has to prove itself against the old one, which takes evals, not just unit tests.
Continuity
The engineers who know the legacy system best are the ones you need on the new build, and both demands arrive at once.
How NuStack Solves It
NuStack modernizes legacy software with an AI-driven delivery lifecycle (AI-DLC).
We don't replace your team or run a rival rewrite; we add AI-native engineering capacity where your program is constrained, following your rhythm, artifacts, and governance.
Four Ways We Plug In
01
AI-DLC Delivery Pods
Small, senior pods join your rewrite and work to your cadence and tracker. They turn requirements into bolt-ready specs, so construction never waits on definition.
02
Customer Migration
We map each customer's footprint against your release plan, build the migration tooling, UAT workbooks, and kits, and run the first customer cohorts with you.
03
Agent Eval & QA Engineering
We build golden datasets, edge and adversarial cases, and eval-regression gates on every merge, alongside security and tenant-isolation checks.
04
Run & Protect
We keep your live platform healthy with fixes and committed enhancements, so your core team can move to the new build without your customers feeling the shift.
How It Works
Every engagement runs the same AI-DLC lifecycle, with a human accountable for every change.
PHASE 1
Inception
We stand up the steering files, sandbox, and CI before any agent writes a line of code.
PHASE 3
Design Gate
We settle usability and architecture before construction begins.
PHASE 5
Evals & Gates
Every merge passes automated tests, security scans, and eval-regression gates.
PHASE 2
Elaboration
Every unit of work carries its spec as the source of truth: a product brief, user stories, non-functional requirements, risks, and measures. Rejected approaches are recorded too, with the reasoning behind them.
PHASE 4
Construction
Agents build in one-to-three-day increments, in a sandbox with no production access, and an engineer reviews every change.
PHASE 6
Staged Rollout
Releases ship behind feature flags, in stages, with migration kits and UAT workbooks ready before any customer moves.

Why Coditas
Domain-trained Engineers
Our teams learn your domain and product before they build, so they help with requirements rather than waiting on them.
Built to Work Alongside You
We plug into your architecture, requirements, and migration leads. We don't compete with them.
Established AI-DLC Practice
We already run enterprise programs on AI-DLC, with agents in the loop and humans accountable for every change.
Low-risk Entry
You can begin with one constrained workstream, a pod, a migration track, or eval engineering, and expand from there.
