Built Alison.AI’s RAG and agentic AI system from scratch, designing the end-to-end pipeline (embeddings, vector search, chunking, and autonomous agents) that extracts creative insights from 10K+ ad creatives/week, saving ~6 hours of manual work per client per day. Scaled client onboarding from 5 to 50+/month with an automated ingestion pipeline and tightened infrastructure/security by moving workl

Led the post-acquisition integration to GA in under 3 months by integrating 12+ microservices from Seekret into Datadog’s Universal Service Monitoring. Rebuilt the React/TypeScript visualization layer to make dashboards 50% faster and ran knowledge transfer sessions for 50+ engineers, reducing ramp-up from weeks to days.

As an early engineer, served as primary technical contact during due diligence—screening 50+ candidates and helping set the hiring bar as the company scaled. Reshaped the distributed architecture by introducing ClickHouse, moving to event-driven microservices, and running 12+ Kubernetes services across a polyglot stack (Node.js gateway, Go ingestion, Rust eBPF capture, Python pipelines), while als

Built a Scratch-to-EV3 compiler used by 150K+ students across 30+ countries by designing a block-to-bytecode compiler (AST extraction, type resolution, EV3 code generation). Continued as primary technical owner after the Mindflow acquisition to implement a Scratch-to-Unity runtime engine supporting real-time multiplayer classroom sessions and expanded the platform with i18n/RTL-LTR (5+ languages)

Architected and shipped a real-time multiplayer Unity engine with a custom Rust networking layer, which was the flagship deliverable that led CoderZ to acquire the studio. As Engineering Lead, led a 4-person team and delivered across domains including React + Node.js enterprise dashboards, Elasticsearch analytics with sub-second queries over millions of records, and a C++ to Electron desktop migra

Ran an independent practice for 2 years delivering production systems for 10+ startup and enterprise clients end-to-end using React, Node.js, GraphQL, and React Native. Built a serverless PWA for Israel’s largest mall operator (18 malls), implementing offline-first caching and push notifications (delivered via Beatman agency).

Completed a Full Stack Software Development program covering backend and frontend engineering, data structures, concurrency, and design patterns such as SOLID and MVC.

Earned a Bachelor of Computer Science with a focus on algorithms, data structures, system architecture, object-oriented design, and discrete mathematics.
