From SOLID to Claude Code — Paul applies classical engineering principles accelerated by agentic AI workflows to deliver faster, with fewer defects.
The foundations of maintainable, testable, and extensible code.
One class, one reason to change.
Each module does exactly one thing — making it easy to test, easy to change, and easy for the whole team to understand.
// ❌ Too many responsibilities
class UserService {
save(user: User) { /* DB */ }
sendWelcomeEmail(user: User) { /* Email */ }
}
// ✅ SRP
class UserRepository { save(user: User) {} }
class EmailService { sendWelcome(user: User) {} }Open for extension, closed for modification.
A system should accommodate new behaviours without modifying existing code — through abstractions and interfaces rather than conditionals.
interface Exporter { export(data: Data): void; }
class CsvExporter implements Exporter { ... }
class JsonExporter implements Exporter { ... }
// Add a new format = new class, 0 modifications.Subtypes must honour the contract of the parent type.
Any object of a subclass must be able to replace its parent type without changing program behaviour — ensuring the integrity of object hierarchies.
class Rectangle { width: number; height: number; }
class Square extends Rectangle {
// ❌ overriding set width violates Rectangle's contract
}Many small interfaces beat one large one.
Don't force implementors to depend on methods they don't use. Focused interfaces reduce coupling and simplify testing.
// ❌ Interface too broad
interface Worker { work(): void; eat(): void; }
// ✅ ISP
interface Workable { work(): void; }
interface Feedable { eat(): void; }Depend on abstractions, not implementations.
High-level modules must not depend on low-level modules — both should depend on abstractions. Fundamental for testability via dependency injection.
// Dependency injection via interface
class OrderService {
constructor(private readonly repo: OrderRepository) {}
// repo can be a mock in tests, a real DB in prod
}70+ specialized agents. 20+ orchestrations. Faster delivery, higher quality.
Not autocomplete. Not Copilot. Paul's agents write, test, and review code autonomously through complete pipelines — each phase validated by a review agent before moving to the next. The result: a senior consultant delivering a team's output, with the consistency of a single hand at the wheel.

Review & delivery
Agent: Code Review
Each phase reviewed by a review agent before advancing to the next.
Writes functional code from specs and business context.
Detects code smells, validates conventions, flags potential bugs.
Generates targeted and comprehensive unit and integration tests.
Implements UI components from design specs.
Verifies WCAG 2.1, colour contrast, aria labels, keyboard navigation.
Identifies bottlenecks and proposes measurable fixes.
This website — innovationcodotek.ca — was built using exactly this agentic workflow: from requirements to implementation, testing, and deployment. Paul doesn't sell a promise. He sells a process he uses himself.
The languages, tools, and pipelines that power delivery.
Next.js, Node.js, React — the modern full-stack for robust, type-safe web applications.
High performance, safety-critical systems — memory safe without a garbage collector.
Data science, automation, embedded tooling — versatility and rapid prototyping.
Automated tests, lint, build and deploy on every commit. Zero surprises in production.
Docker for reproducible builds and perfect parity between development and production. Cloud-native ready.
From unit to end-to-end — every layer protects the next.
Fast, isolated, covering business logic. The foundation for rapid iteration without regressions.
Vitest / pytestVerify boundaries between components — databases, APIs, external services.
Vitest + mocksValidate complete flows from the user's perspective — catching regressions before production.
PlaywrightBefore human review, Paul runs code through an agentic workflow that detects code smells, validates naming conventions, and flags potential bugs. Human review then focuses on architecture and business context — not mechanical errors.
The right pattern for the right problem.
Factory, Builder, Singleton — abstracting concrete implementations for extensible systems.
Observer, Strategy, Command — event-driven flows and state-machine-driven embedded systems.
Repository, Adapter, Facade — clean integration between heterogeneous systems.
Assess
Understand the problem, architecture, specifications.
Develop
Code with AI + SOLID, pair programming.
Test
Automated tests, AI review, lint, CI.
Refine
Iterate on feedback, refactor.
Deliver
Deploy to production, docs up to date.
No OOP — but always rigour.
FPGAs and microcontrollers operate under severe resource constraints: no garbage collector, no frameworks. C/VHDL code is organised as state machines, modelled in UML (activity diagrams) before being coded. Quality principles adapt, they don't disappear: explicit state transitions, documented interfaces, logic testable in isolation.
Whether it's a SaaS application, an embedded system, or an AI/ML project — Paul delivers with the expertise of a senior consultant and the speed of an agentic AI pipeline.
