Backend engineer at asya.ai building production email automation with Python, FastAPI, PostgreSQL, and AI.

Message

At asya.ai, I own a production email automation pipeline that connects IMAP, SMTP, Microsoft 365, and Gmail with AI-assisted replies and follow-up actions.

I build and maintain backend systems with Python, Flask, FastAPI, and PostgreSQL. After migrating list data from the filesystem to PostgreSQL, I cut load time from minutes to milliseconds.

I also design prompts and ship AI chatbot systems for task automation, integrate third-party services, and built a Chrome extension that generates AI reply drafts through a backend API.

On my personal production site, mihails.dev, I built visitor analytics and a private dashboard with FastAPI and PostgreSQL, deployed behind Nginx on AWS EC2. I work directly with customers to scope needs and deliver features, and build React Native apps or internal tools when needed.
