# Milos Cvetkovic > Senior Full Stack Engineer building AI-native systems: self-healing agents, legacy rescue and cloud architecture in TypeScript, React and NestJS. ## Case studies - [Self-Healing Agent](https://miloscvetkovic.dev/work/self-healing-agent/index.md): 73% errors resolved autonomously. An AI agent that woke up before you did. It monitored production, diagnosed errors, and opened PRs with fixes—all autonomously. - [Enterprise B2B Platform](https://miloscvetkovic.dev/work/enterprise-b2b-platform/index.md): 40% less complexity. Took a legacy codebase everyone was afraid to touch and turned it into a system the team actually enjoys working on. - [Nx Remote Cache Server](https://miloscvetkovic.dev/work/nx-remote-cache/index.md): 5× faster builds. Why rebuild what hasn't changed? A custom cache server that slashed CI times and gave developers their coffee breaks back. ## Site pages - [Milos Cvetkovic \| Senior Full-Stack Engineer](https://miloscvetkovic.dev/index.md): Senior Full Stack Engineer building AI-native systems: self-healing agents, legacy rescue and cloud architecture in TypeScript, React and NestJS. - [About — Senior Full-Stack Engineer](https://miloscvetkovic.dev/about/index.md): I fix the systems everyone else gave up on: 13 years rescuing legacy codebases, now building AI agents that fix their own bugs.
