Senior Software Engineer — Mindhop Inc., White Plains, NY | 2023 – Present
Over Height Vehicle Detection — Real-Time Edge Safety System (NYSDOT)
- Sole architect of production edge-computing system: fault-isolated multi-process architecture in Docker with 7-layer watchdog, 120+ days continuous uptime, ~100MB footprint.
- Dual-sensor correlation (LiDAR TCP + VCA RTSP) with 5-second deduplication; VCA optimization reducing 18 duplicate detections to 1 via confidence plateau detection.
- MQTT/WebSocket distribution for TMC dashboards; AVRO pipeline to Apache NiFi; automated field installer with encryption and hardware integration.
DMS Control API — Highway Dynamic Message Sign Command & Control
- Sole architect: reverse-engineered NTCIP 1203 from MIB specs to build vendor-agnostic driver framework (Daktronics VFC-3000, generic NTCIP) with factory/registry pattern and 3-tier quirk resolution.
- Full protocol lifecycle: MULTI validation, CRC computation, activation sequences, readback verification. 15+ REST endpoints, 31 E2E tests, Kafka streaming.
Device Status Monitoring — Network Infrastructure at Scale (UDOT)
- Architected async monitoring for 2,400 devices / 750+ subnets: 90%+ cycle time reduction (54 min → 5 min) via asyncio/aiohttp with 2,000 concurrent workers.
- APScheduler per-group scheduling (12/24/48 min), PostgREST streaming writes, Docker + AWS (ECR, Secrets Manager). 120+ hours zero-error operation.
Alert Routing & Video Streaming — Event Processing & Low-Latency Camera Infrastructure
- Real-time alert system (Flink/Kafka) dispatching email, SMS, WebSocket notifications. Video platform: Flask + FFmpeg + WebRTC/HLS delivery with React monitoring UI.
Front-End — DotStream React/Next.js Monorepo
- Contributor to production Next.js 15 / React 19 / TypeScript monorepo (Turbo, pnpm). Integrated OHVD real-time subsystem: alert providers, WebSocket streams, map panels, Kendo grids.
