01. About

Senior Software Engineer with 5+ years architecting and delivering distributed systems and cloud infrastructure at scale.

I specialize in backend systems, cloud infrastructure, and asynchronous event-driven architecture, with deep expertise in Python, FastAPI, AWS, RabbitMQ, and Celery. I've led large-scale system refactors, CI/CD automation, and performance optimizations for high-throughput platforms — comfortable operating close to the system level in Linux-based environments.

Currently at Yodeck, leading infrastructure and backend systems including a Kubernetes migration. Previously at Transifex, contributing to a large-scale enterprise localization platform.

I focus on distributed services, async processing, and making things behave predictably under real-world conditions. Outside of work, I'm actively building LLM-powered agents and tooling — exploring how autonomous systems can operate reliably in production. I'm also interested in security, systems programming, and hardware.

Current interests

  • Event-driven systems that hold up under load
  • Kubernetes beyond the happy path
  • AI agents that operate in production

Reactive Task Dispatch: Why Celery Beat Is Not Enough

Celery beat is a clock; model signals are interrupts. Move from polling to event-driven dispatch for lower latency and better failure modes.
