I specialize in building robust, low-latency control systems and monitoring stacks for renewable energy and home automation. My work focuses on the Victron Energy ecosystem, where I've developed a comprehensive suite of tools to bridge the gap between industrial energy hardware and modern web/embedded technologies.

• Systems Programming: Real-time control loops in Python and high-performance services in Go and Rust.
• Embedded & IoT: Custom firmware development with ESPHome, Bluetooth (BLE) proxying, and MQTT-based messaging.
• Energy Management: Advanced ESS (Energy Storage System) logic, split-phase compensation, and grid-zero targeting.
• Full-Stack Monitoring: Real-time dashboards (FastAPI, Vue.js, Tauri) and time-series observability (TIG stack).
• Infrastructure as Code: Managing complex GitHub organizations and repository configurations via Terraform.

My project suite forms a complete ecosystem for home energy management:

Advanced ESS Grid-Zero Controller

• Developed a high-frequency (3Hz) control loop to maintain zero grid feed-in for split-phase systems.
• Implemented complex logic for EV charger exclusion, battery protection, and multi-mode energy strategies.
• Tech: Python, D-Bus, Home Assistant API, MQTT.

Real-time Energy Observability

• Built high-performance monitoring interfaces with WebSocket-based live updates.
• The Go version provides a single-binary deployment with sub-10ms latency and minimal memory footprint.
• Tech: Go, FastAPI, Vue.js, WebSockets, Docker.

Cross-Platform Monitoring Suite

• Developed a native desktop application using Tauri and Rust for low-resource system monitoring.
• Implemented secure MQTT communication with built-in security auditing and fuzz testing (OSS-Fuzz).
• Tech: Rust, Tauri, TypeScript, Vite.

Embedded Battery Management Bridge

• Created a robust BLE-to-MQTT proxy to offload unstable Bluetooth connections from the main controller.
• Developed the D-Bus bridge that dynamically registers multiple battery chains as native Victron devices.
• Tech: C++ (ESPHome), Python, BLE, MQTT.

System Observability & Time-Series Data

• Deployed a comprehensive TIG (Telegraf, InfluxDB, Grafana) stack for long-term telemetry storage and visualization.
• Implemented automated log shipping with Loki and GitHub webhook-based auto-deployment for the monitoring infrastructure.
• Tech: Docker, Telegraf, InfluxDB, Grafana, Loki.

Infrastructure as Code

• Manages the entire victron-venus organization, including 10+ repositories, branch protections, and CI/CD secrets.
• Tech: Terraform, GitHub Actions, HCL.

• GitHub: @4alvit
• Organization: @victron-venus
