AVIATION: Founder & Chief Architect of a sovereign AI-powered aviation platform (Stellar RS “ACommand”, 2017-2025), delivering a large-scale, big data-driven AI ecosystem for aviation training and operational support. Designed a cloud-native platform with extensibility to portable, military-grade “box-ready” deployments, integrating streaming databases, machine learning pipelines, model development, fine-tuning, and data distillation across multiple domains. The platform enables immersive AI-driven flight and ATC control simulation with real-time decision support. Backed by Microsoft for Startups, classified by ISUN as innovation, and presented at international AI events (London, Paris, 2026).

Engineered a low-latency Voice AI / VoIP stack (VoiceLive) with bidirectional audio streaming over WebSockets, server-side VAD, and dynamic prompt orchestration. Combined Microsoft Speech SDK pipelines with LLM inference layers to deliver multilingual, domain-adapted conversational agents for aviation radio and training scenarios.
Built a distributed, event-driven processing architecture using Kafka (Strimzi), with ingestion, chunking, and embedding workers executing asynchronous pipelines for vectorization, retrieval, and AI inference at scale. Integrated OpenSearch-based vector indexing (~30k+ embeddings) to enable retrieval-augmented reasoning and contextual decision support.
Deployed and operated the platform on Kubernetes (AKS) with Istio service mesh, implementing secure, scalable microservices, WebSocket ingress (NGINX), and fully automated CI/CD pipelines (Azure DevOps → ACR → AKS). Designed portable, “box-ready” edge deployments for constrained and high-security (military-grade) environments.
Core stack includes Node.js / Express backends, React + TypeScript + Vite frontends, Docker, Kubernetes, Kafka, OpenSearch, Azure cloud services, and real-time VoIP/streaming systems, enabling high-throughput AI workloads and low-latency interaction loops.
Recognized by Microsoft for Startups, classified as innovation by ISUN, and presented at international AI conferences in London and Paris (2026).
