I build high-load backend systems in Node.js: real-time pipelines, stateful event-driven platforms, and performance-critical infrastructure where predictable latency matters more than fancy abstractions.
- Focus: performance, reliability, observability, minimal overhead
- Stack: Node.js / JavaScript, HTTP/WebSocket, MongoDB, Linux, Docker
- Interests: Node/V8 internals, runtime behavior, Chromium/Electron patching
A personal engineering playground / ecosystem for building zero-dependency, high-performance backend infrastructure (HTTP/WebSocket core, shared standards, tooling).
- GitHub org: SwarmMachina
- Philosophy: simple internals, tight control, minimal moving parts
- Data ingestion + normalization from 20–40 sources
- Services handling up to 10k RPS
- High-frequency updates (~50ms cadence), TTL-based freshness, consistency under churn
- Hot-path optimization to reduce latency and GC pressure
- Scenario engine: triggers, auto-replies, warm-up flows, timers, TTL
- Orchestrating 1–3k active dialogues, 200–500 scenarios, 20–80 events/sec
- Retries, deduplication, state recovery
- Real-time HTTP/WebSocket updates with 50–100ms predictable latency
- Custom HTTP/WebSocket frameworks with minimal overhead
- Zero-dependency approach when it improves control and reliability
- Internal tooling and admin panels (Vue 3) focused on engineering workflows
- Patching and building Chromium / Electron from source
- Integrating custom builds with backend services
- Zero-deps patterns for production-grade Node.js services
- V8 / Node.js internals, profiling, GC behavior
- Chromium/Electron build & patch workflows

Always happy to chat about backend architecture, performance, and runtime internals.
