I'm actively seeking professional opportunities or freelance collaborations. I'm always keen to:
- Build production-ready applications (full-stack web apps, AI-powered tools, developer platforms)
- Architect cloud infrastructure (AWS/Azure serverless, event-driven systems, scalable APIs)
- Integrate AI/ML workflows (LangChain agents, OpenAI/Anthropic APIs, RAG systems)
- Contribute to open-source (TypeScript/React utilities, DevOps tooling, .NET APIs)
