AI in the service of disciplined engineering


> whoami

Backend-focused engineer working in .NET APIs, systems architecture, and AI-augmented development workflows.

I use AI often, but I use it in service of disciplined engineering, not in place of it.

My focus is building software that remains clear, maintainable, and dependable after the first demo, after the happy path, and after requirements start changing. I care about sound architecture, clean boundaries, thoughtful specifications, and code that can survive real-world pressure.

I’m especially interested in:

  • developer tooling
  • backend system design
  • API architecture
  • spec-driven development
  • AI workflows grounded in engineering judgment

After spending three years away caring for a family member, I’m back with sharper fundamentals, deeper architectural focus, and a stronger sense of the kind of software worth building.

If I don’t understand how a system works, I learn it until I do.

amodelandme is exactly what it sounds like: a builder, a model, and a serious respect for the craft.


> projects

FeatureFlagServicein active development

Azure-native. .NET-first. AI-assisted feature flag management.

🔗 Feature Flag Service Repository

A developer tooling project for engineering teams running .NET on Azure that want a serious feature flag platform without the pricing weight of LaunchDarkly or the rough edges of lighter alternatives.

Stack        .NET 10  ·  ASP.NET Core  ·  Azure (Key Vault · App Insights · Container Apps)
AI Layer     Azure OpenAI  ·  natural-language flag health analysis  ·  stale flag detection
SDK          Production-ready .NET SDK ships alongside the service
Model        Open core  ·  MIT licensed  ·  self-hostable

What makes it different:

  • Azure-native from day one
  • Built specifically with .NET teams in mind
  • AI-assisted flag analysis that helps surface operational and cleanup issues
  • Fast local setup with a working service and SDK in minutes

Validation goal: clone the repo, run docker compose up, and get a usable flag service with the .NET SDK and AI analysis in under 15 minutes.


Specwrightspec-driven backend development workflow

Design-first. .NET-native. AI-assisted engineering workflow.

🔗 Specwright Repository

A workflow and tooling kit for backend engineers who want to move beyond ticket-driven implementation and toward spec-driven system design.

Specwright is built around the idea that strong software starts with clarity: clear architecture, clear current-state documentation, clear implementation specs, and clear feedback loops between design and code.

It combines:

  • living project documents
  • feature-level specs
  • implementation notes
  • AI-assisted engineering roles

The goal is not to automate judgment away. The goal is to give disciplined engineers a better development loop.
