What I'm looking for

I'm looking for a remote or hybrid full-time or B2B role where I can own backend services from data model and architecture through Docker deployment, APIs, automation, and production operations.

I've shipped more than a dozen production Python systems end to end, including modular pipelines, async services, task queues, scheduled jobs, and products for paying clients.

Across personal and client projects, I've built a Telegram bot ecosystem of seven-plus products, including QA automation, an AI video-script generator using Anthropic Claude, and an Airtable-integrated client brief collector. I also created an AI-powered Instagram competitor analysis platform that generated 60+ automated reports with funnel mapping, sentiment, and JTBD analysis.

For a Google Search Console SEO analytics SaaS, I built five production iterations with OAuth2 integration, AI-powered OpenAI recommendations, multi-site support, and scheduled data syncs deployed on Render.com.

I'm comfortable owning a service from data model to deployment, working daily with Python, FastAPI, Celery, PostgreSQL, Redis, Docker, and asynchronous integrations.
