INSIDE THE MIGRATION
Follow one application through the pipeline.
The engineering behind the outcome.
01 / 07
We combine onboarding, structural analysis, and AI-assisted dependency resolution.
Onboarding establishes how the application builds and runs, its dependencies, and migration scope. AST parsing identifies artifacts and relationships. AI-assisted analysis helps resolve dynamic $injector calls whose targets depend on runtime variables, using application context. Resolved targets are checked against registered artifacts; unresolved cases remain visible for review.
An application inventory and dependency model
Onboarding + AST + AI-assisted dynamic injection resolution
Type information is extracted from source and resolved across connected artifacts. Unknowns remain visible for further resolution.
Typed contracts that guide code generation
Local evidence → cross-file types
Application analysis identifies external libraries and how their APIs are used. Library strategy determines which dependencies to retain, replace, or bridge with adapters. These decisions guide code generation; unsupported mappings remain explicit review items.
Dependency decisions that guide the generated code
Library usage → retain / replace / adapt → generation context
State readers and writers inform typed stores. Dependency waves organize conversion, keeping cyclic groups together. Output strategies include Signals, NgRx SignalStore, and classic NgRx.
Store designs and a dependency-aware conversion plan
State ownership + dependency-ordered migration waves
AI-assisted, artifact-aware generation uses resolved application context. Compiler feedback guides corrections, with AST-based chunking for supported oversized artifacts.
Angular code checked against the compiler
Generate → compile → correct → check again
Runtime comparison examines the legacy and migrated application. Differences and unmeasured behavior remain distinct from passed checks; render success alone is not full functional parity.
Verification results with explicit comparison coverage
Passed ≠ different ≠ not measured
The engagement delivers standard Angular code, a verification report, and outstanding issues for review, followed by a team walkthrough. Release acceptance and go-live are scoped separately.

A simplified view of the process. Analysis and correction can repeat; outputs and timelines depend on the application.

01 · PROCESS
Every file is parsed into a full abstract syntax tree. Module graphs, DI edges, and template bindings are resolved from structure — never regex, never string matching.
$scope trees, watchers, and broadcasts are lifted into an explicit typed model: what state exists, who reads it, who writes it, and where it should live.
Generated code is fed back through the Angular compiler and strict tsc on every iteration. Nothing ships that does not build. The compiler is the judge, not us.
— VERIFIED IN THE BROWSER
The migrated app is built, served, and driven route by route through headless Chrome via the Chrome DevTools Protocol. A route passes only if it renders, throws zero console errors, and completes its network calls. “It compiles” is not the bar. “It runs” is. Read the verification report →

| PATH | TIMELINE | COST | WHERE YOU END UP |
|---|---|---|---|
| Hand rewrite, in-house | 12–24 months | $500K+ | Roadmap frozen; two codebases in flight the whole time |
| Consultancy | Quarters, T&M | Open-ended | Knowledge leaves when they do |
| Extended-support subscription | Forever | $25–75K / yr | Still on AngularJS. Zero progress, compounding rent |
| SoftwareMigration | Days | Fixed scope | Plain Angular your team owns, with a verification report |

03 · HANDOVER
Work directly with the founder-operator: 14+ years of frontend engineering, from the first audit to your team’s handover.
04 · YOUR QUESTIONS
In an isolated, single-tenant environment provisioned for your engagement and destroyed after delivery. For regulated codebases we run the pipeline inside your VPC; your code never leaves your network.
The pipeline is AST- and compiler-driven; model assistance operates inside it on scoped fragments, under a zero-retention agreement and a US/EU-only model-provider allowlist. Your code is never used for training. DPA and subprocessor list available before you send anything.
They are flagged, not guessed. Anything the pipeline cannot prove correct lands in the issue registry with the file, the reason, and a suggested owner on your team. On the reference migration that was 11 files out of 745.
About two hours up front: repo access and a walkthrough of how you build and run the app. At the end, a review pass over the flagged list — typically half a day for a senior engineer. A training walkthrough of the new codebase for your Angular developers is included at handover.
AngularJS reached end-of-life in January 2022. Advisories since then — including CVE-2025-4690, CVE-2025-2336, CVE-2025-0716 and CVE-2024-21490 — will never receive patches, and PCI DSS 4.0 treats EOL software as a control failure.
A founder-operator with 14+ years of frontend engineering across frameworks, running a deterministic pipeline. The pipeline does the scale; the human does the judgment. No offshore bench, no juniors touching your code — you talk to the person who runs the line.
05 · GO DEEPER
LET’S LOOK AT YOUR APP
We walk through the pipeline against your actual codebase and a real verification report, and you leave with a scoped plan — whether or not you use us.
A live pipeline walkthrough, your codebase questions, and a scoped plan. No code needed before we agree on secure access.
