Dependency Version Conflict - Incompatible Package Versions
npm install fails or warns about version conflicts. Packages require different versions of the same dependency.
Error: 'peer dep missing' or 'conflicting peer deps'
Error Messages You Might See
npm ERR! peer dep missing: requires react@17
npm WARN: peer dependencies not satisfied
conflicting peer dependency: react
Incompatible dependencies detected
Common Causes
- Two packages require different major versions of same dependency
- Peer dependency mismatch - library requires React 17 but you have 18
- npm version changed how it handles peer deps (npm 8+ is stricter)
- Dependency not compatible with Node version
- Outdated package not updated to support new dependencies
How to Fix It
Check what's conflicting: npm list [package-name]
Update package: npm update package-name@latest
If incompatible: remove older package and install newer
Force install (risky): npm install --legacy-peer-deps
Better: find package compatible with your versions or replace with alternative

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

Sage Fulcher
Hey I'm Sage! Im a Boston area software engineer who grew up in South Florida. Ive worked at a ton of cool places like a telehealth kidney care startup that took part in a billion dollar merger (Cricket health/Interwell health), a boutique design agency where I got to work on a ton of exciting startups including a photography education app, a collegiate Esports league and more (Philosophie), a data analytics as a service startup in Cambridge (MA) as well as at Phillips and MIT Lincoln Lab where I designed and developed novel network security visualizations and analytics. I've been writing code and furiously devoted to using computers to make people’s lives easier for about 17 years. My degree is in making computers make pretty lights and sounds. Outside of work I love hip hop, the Celtics, professional wrestling, magic the gathering, photography, drumming, and guitars (both making and playing them)

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
When should I use --legacy-peer-deps?
As temporary workaround only. Better to update packages to compatible versions. Don't commit with this flag
What's a peer dependency?
Library expects to use your version of a package (React, etc). You install it, library reuses it
How do I check all dependencies?
npm list shows tree. npm ls --depth=0 shows top level. npm outdated shows what can update
