Production AI & Real-Time Edge Systems — From Silicon to Cloud.

Senior Engineer & Principal Architect specializing in complex, high-reliability AI: real-time computer vision, edge-to-cloud inference pipelines, and event-driven microservice architectures.

Background spans edge vision (NVIDIA Jetson, real-time tracking), cloud inference, and mission-critical defense and enterprise infrastructure. Principal architect and lead developer on Cargoseer (customs risk platform acquired by BigBear.ai) and core contributor to field-deployed military video analytics. Available for senior IC roles, system architecture consulting, and selective technical delivery.

Snapshot

Key skills

  • Production AI & Multimodal Pipelines

    High-throughput pipelines integrating Computer Vision, OCR, and LLM reasoning into auditable decision systems (FastAPI, ONNX, cloud & on-prem).

  • Real-Time Edge & Video Analytics

    Optimizing deep learning & classic vision on NVIDIA Jetson SoCs. Low-latency frame processing, target tracking (VOT/MOT), and sensor integration.

  • Distributed Microservices & Messaging

    Event-driven architectures powered by Apache Kafka, PostgreSQL, and Docker containerization engineered for maximum uptime and data throughput.

  • Defense & Mission-Critical Systems

    Battle-tested software engineering across ground, naval, and aerial platforms—from missile boat electronics command to military UAV tracking.

  • Architecture & Ownership

    End-to-end system design, microservice boundaries, interface definition, and single-thread accountability from concept to deployment.

  • Algorithm & Control Engineering

    Deep foundation in signal/image processing, custom pathfinding solvers (A*), gimbal control loops, and hardware driver development.

Case Study 01 — Enterprise AI Architecture

Cargoseer Risk Management Platform (Acquired by BigBear.ai)

Principal Software Architect & Lead Developer | 2024–Present

  • Python
  • FastAPI
  • Apache Kafka
  • PostgreSQL
  • Docker
  • ONNX
  • AWS / GCP
The Challenge

Global port operations require high-throughput risk processing across continuous streams of cargo container X-ray images, OCR data, and shipping documents with zero-downtime reliability.

Architecture & Execution
  • Designed and built the entire core microservices infrastructure using Apache Kafka event-driven messaging and Python/FastAPI backend services.
  • Developed Cargoseer Inspector (X-ray & documents risk management platform) and Cargoseer Cortex (data accessibility & retrieval engine).
  • Implemented GPU-accelerated ONNX inference pipelines in data-center paths, integrating computer vision, OCR, and LLM-based reasoning into auditable decision workflows.
  • Built full Docker-based deployment infrastructure supporting both cloud (AWS, GCP) and air-gapped on-premises port deployments.
Outcomes & Impact
  • Full nationwide deployment across all port operations in El Salvador.
  • Architecture and production readiness served as the primary factor leading to Cargoseer's acquisition by BigBear.ai.

Profile

About

Electrical Engineer (Technion B.Sc.) turned hands-on AI Architect and Systems Engineer. I have spent over a decade engineering high-stakes software where latency, reliability, and precision matter—from national border customs risk engines (Cargoseer/BigBear.ai) to combat-tested defense video analytics platforms (Axon Vision / Elbit Systems). Whether architecting event-driven cloud microservices, developing real-time VMD tracking algorithms for NVIDIA Jetson hardware, or writing low-level drivers, I bridge the gap between complex mathematical algorithms and production-hardened execution. Full CV available on request.
