I build and operate production SaaS systems from bare metal to application layer — no abstraction layers I don’t control.
Frontend: SvelteKit, Bun, Vite, Tailwind CSS — modern toolchain, no unnecessary complexity.
Backend: Elixir/OTP with Phoenix, GenServer, Ecto, Bandit & Distributed Elixir for fault-tolerant, concurrent services; Go and Rust for systems-level workloads and performance-critical components; Python for data pipelines and tooling.
Databases: PostgreSQL with HA setups for relational workloads, SQLite for embedded use cases.
Infrastructure: Bare-metal deployments on AlmaLinux across colocated servers. Proxmox VE for hypervisor management and VM/LXC orchestration; Ceph for distributed, self-healing block and object storage across nodes. No managed cloud, no Docker overhead — direct control over performance, resilience, and cost.
