To the Known team:

Your stack reads like my career summary. At Remind, I built & operated infrastructure for 60+ microservices serving 30M users on AWS. I managed the RabbitMQ cluster handling millions of messages daily across event-driven services, performed PostgreSQL upgrades & migrations at scale, & introduced Datadog with container agents for APM & observability. During COVID-19 lockdowns, usage spiked dramatically as schools went remote. Systems stayed up because the distributed architecture & monitoring I'd built gave us visibility into what was breaking before users noticed.

I've built production systems across multiple languages & frameworks. unsandbox.com is a multi-tenant code execution PaaS I built in Elixir with containerized isolation & resource quotas. uncloseai-speech is a real-time speech API I built in FastAPI handling concurrent audio workloads. At Remind, I shipped Python services across the microservice fleet & managed Docker containers on ECS. I write Dockerfiles, deployment pipelines, & infrastructure-as-code daily. Kubernetes, PostgreSQL, event-driven architecture, & message queues are core to how I design systems.

I bring 15+ years shipping production systems & 12+ years working remote. My security engineering background at Mandiant & Cofense gave me experience in SOC2/FedRAMP environments where reliability & compliance were non-negotiable. I've also built frontends in React & Vue for my SaaS products, so I can contribute across the full stack when needed.

I'm looking for a team building real distributed systems where I can contribute meaningfully. Known's focus on data-driven products with serious backend infrastructure is exactly that.
