What I'm looking for

I'm looking to build scalable full-stack and agentic AI products where I can own architecture through deployment, work with modern cloud systems, maintain strong quality standards, and mentor engineers.

I've delivered full-stack applications and AI-powered products for Oak Tree Software, CDN Solutions Group, Sugow Technologies, and Pix Brand, owning architecture through deployment. My work spans React.js, Next.js, TypeScript, Node.js, Python, AWS, GCP, and production-quality CI/CD.

I've built agentic AI workflows with LangChain, CrewAI, OpenAI, and Claude APIs, including CloudVoice, a self-hosted AI-powered VoIP platform with real-time speech and audio streaming, and Cognitiv.AI, an exchange trading platform with an LLM-based trading assistant. I’ve also delivered serverless e-commerce, payment, IoT analytics, airline booking, insurance, and crypto-transfer platforms.

I focus on clean code, strong test coverage, scalable cloud infrastructure, and end-to-end ownership. I’ve mentored 5+ engineers in React.js, Next.js, Python, AWS serverless, and AI-assisted development.
