What I'm looking for

I seek product-focused roles in fast-moving teams building scalable fintech or AI systems, with ownership, low bureaucracy, and opportunities to build agentic AI solutions.

I am a senior backend engineer with 6+ years building production-grade systems in Python (Django, FastAPI) focused on fintech, blockchain, and AI/LLM integrations. I deliver scalable, secure backend architectures—optimizing PostgreSQL, building async task queues with Celery/Redis, and applying TDD to improve reliability and reduce production bugs.

I've shipped high-impact products at startups and academies, including crypto exchange platforms, AI-powered learning systems, and decentralized fintech services. I combine deep technical expertise with a product-focused, ownership mindset and enjoy building agentic, AI-enabled solutions that improve performance, uptime, and user experience.
