I build backend systems with NestJS and TypeScript, including e-commerce, project management, chat, and learning-management APIs. My E-Commerce Store API uses a dynamic EAV product system and integrates Stripe, Redis, and RabbitMQ.
On LiveManga, I developed an AI system for manga text detection, colorization, denoising, and upscaling, exposed through a Django REST API with a Flutter reader. I also build cross-platform apps with Flutter and Firebase, including a construction operations app with a voice-to-expense pipeline.
In my current freelance work, I design and test n8n workflows for AI agents, LLM-driven pipelines, and reporting automations that connect ad platforms with spreadsheets and databases. My experience also includes running paid-media campaigns on Meta and TikTok, and using performance data to optimize them.
