Hi, I'm Itay Lifshitz — an engineer and AI specialist. I build software, websites, mobile apps, and cybersecurity solutions for businesses across Israel and worldwide. Fifteen years in. Solo by design. On-demand senior team when scale requires it.
I'm Itay Lifshitz — an independent software engineer based in Israel. Over the past 15+ years I've built software across the full stack: AI and automation, cybersecurity for teams that can't afford a breach, custom platforms and mobile apps, and the IT infrastructure that holds it all together. I served in IDF Unit 8200, where systems must not fail and must not be detected failing.
This is a one-person operation by design. I handle strategy, architecture, and the critical code personally. When a project needs specialized hands — design, a specific platform, extra capacity — I bring in trusted freelancers I've worked with for years. But you're always working with me. No handoffs. No agency layers. I also write about AI every week in Hebrew at lifshitz.tech — 1,000+ readers and growing.
Public work, technical projects, and live systems. Every project is built end-to-end — from scoping to deployment.

asikalfon-criminal.vercel.app ↗ProblemDaily DDoS attacks were causing 4-6 hours of downtime per incident, driving users away from the community.
ApproachDesigned and deployed a custom traffic-fingerprinting firewall with automatic blackhole routing, tuned to the specific attack patterns.
ProblemClient needed to catch suspicious crypto transactions before the fiat gateway - manually reviewing everything was impossible at scale.
ApproachBuilt an ML-powered on-chain transaction scoring engine with 92% catch rate, integrated into the existing risk pipeline.
ProblemEnterprise rolling out internal LLMs needed protection against prompt injection, data exfiltration, and hallucination in compliance-bound workflows.
ApproachDesigned a multi-layer input/output validation pipeline, sandboxed runtime, and continuous evals framework.
// hardening-pipeline.ts const guard = pipeline({ layers: [ inputValidator("strict"), injectionFilter("v3"), outputSanitizer(), evals.continuous() ], sandbox: true }) // 0 escalations in prod
ProblemRetail traders were missing entry signals because manual market scanning couldn't keep up with real-time price action across multiple stocks simultaneously.
ApproachDeveloped an AI-powered algorithmic trading system with a real-time stock alert engine - streams live market data, identifies patterns, and fires precision entry/exit signals automatically.
More projects added as clients give the green light.
