Built a real-time security platform for 200 cameras by integrating RTSP with go2rtc/WebRTC and deploying YOLO/InsightFace inference accelerated with TensorRT. Connected the computer-vision pipeline to MQTT for messaging and implemented a React-based monitoring experience with sub-2-second alert delivery. Designed a modular monolith backend using Hexagonal Architecture, separating domain logic from PostgreSQL/Prisma, InfluxDB, MQTT, and Azure Blob Storage adapters. Implemented Node.js/Express APIs with JWT and RBAC, and created event-driven IoT workflows using MQTT QoS 1 and zero-touch ESP8266 provisioning. Used PgBouncer to reduce database connection pressure by cutting app connections from 201 down to a 20-connection pool.

Architected a distributed IoT security platform ingesting real-time telemetry from multi-site field devices. Built RESTful services using Node.js, Express, and PostgreSQL with JWT and RBAC. Implemented dual-channel messaging with MQTT and WebSockets to achieve sub-second event propagation to browser clients. Applied Clean Architecture with dependency injection to isolate domain logic and improve unit test coverage. Containerized the application lifecycle with Docker Compose to ensure strict Dev/Prod parity.

Designed full-stack product workflows across React, Node.js, PostgreSQL, and Prisma, covering relational data modeling, authentication, validation, and REST API design. Built responsive client-state and server-state flows with optimistic updates, rollback strategies, caching, and asynchronous mutations to keep the user experience fast and consistent. Integrated LLM-powered capabilities into deterministic application workflows, carefully handling latency, failures, and state transitions. Ensured secure operation with OAuth 2.0 and session-based authentication while coordinating reliable execution paths around AI outputs.
