Systems Architect & QA Lead

Orchestrating Flawless Systems with AI

Q: What services does Sahin Aytac offer?

Sahin Aytac offers AI agent orchestration, NestJS and Next.js full-stack architecture, RAG pipeline design, legacy monolith modernization, automated QA frameworks, and enterprise software consulting — all delivered remotely from Ontario, Canada.

Q: Where is Sahin Aytac based?

Sahin Aytac is based in Ontario, Canada, and operates fully remotely, serving clients in Canada, the United States, Europe, and globally.

Q: How does the solo architect model work?

By orchestrating advanced AI agents for implementation and applying deep domain expertise for architecture decisions, Sahin operates as a highly efficient single point of contact — eliminating the communication overhead of traditional agencies.

I merge decades of domain expertise with advanced AI agent orchestration and rigorous test automation. I deconstruct legacy monoliths, build scalable modern architectures, and guarantee absolute software quality with zero-tolerance testing.

How Sahin Works

AI Orchestration

I delegate routine implementation to advanced AI agents, acting as the high-velocity controller.

Architect's Guardrails

I define precise data schemas and architectural constraints for the AI based on deep domain experience.

QA & Testing Filter

Leveraging my software testing engineering background to preemptively catch edge cases and logic flaws.

Forget Traditional Software Pipelines

The Solo Software Factory

By leveraging AI orchestration, you eliminate communication friction, revision bottlenecks, and technical debt build-up. The distance between concept and resilient production is minimized.

Legacy Code Deconstruction

Scanning legacy, undocumented, or monolithic systems. I map dependencies, identify database bottlenecks, and blueprint modernization strategies in minutes using AI.

Modern Architecture Design

Building highly-scalable, modern microservices or modular architectures powered by NestJS, Next.js, and Docker containerization with optimized data layers.

Zero-Tolerance QA

Implementing rigorous testing frameworks. I define boundary conditions, security guardrails, and automated verification before code ever touches production.

The Journey

Professional Evolution

A trajectory built on breaking systems to understand them, leading teams to build them, and now orchestrating AI to scale them.

Present Phase

AI-Driven Solutions Architect

Transitioned from traditional team management to single-handedly orchestrating autonomous AI agents, designing Next.js/NestJS architectures, and implementing enterprise RAG systems.

Growth Phase

Senior Software Developer & Lead

Led engineering efforts on monolithic to microservice migrations. Designed scalable databases and integrated complex third-party APIs while maintaining high code quality standards.

Foundation

QA Automation Engineer

Built the foundation of my architectural mindset: testing systems to their breaking point. Developed automated regression suites and edge-case scenarios.
