About

Who I Am

I'm a Full-Stack Developer with a strong Solutions Architect background, building scalable web applications, AI-enabled systems, and AWS cloud infrastructure.

My work spans backend systems with Python/Django/FastAPI, modern React frontends with TypeScript and Next.js, and production cloud deployments on AWS — from containerized ECS services to serverless Lambda functions.

I've worked on freelance projects ranging from AI-powered automation agents to real-time validation platforms, always with a focus on clean architecture, maintainability, and reliable delivery.
