SToFU Systems is a senior engineering partner for cybersecurity, reverse engineering, low-level systems, AI security, and critical software delivery. We help founders, CTOs, and product owners make hard technical bets with evidence: audit the system, expose risk, build the fix, and ship the roadmap. Core work: - Security audits and certification for software, mobile, AI systems, networks, and critical infrastructure - Reverse engineering for firmware, malware, protocols, legacy software, and opaque binaries - Low-level and systems engineering in C, C++, Rust, Assembler, Python, Java, C#, and JavaScript - Kernel, driver, OS internals, Win32/64, WinNT API, Linux, macOS, CUDA, OpenCL, cloud, and database work - AI systems engineering: agentic workflows, AI governance, RAG security, inference optimization, private AI, and evaluation labs - HFT, MEV, blockchain infrastructure, smart contracts, bots, nodes, and latency-sensitive systems - Architecture review, PoC engineering, technical due diligence, TDD, CI/CD, debugging, and delivery rescue We are useful when the product is too important for vague answers: hidden vulnerabilities, unreliable architecture, slow systems, AI-agent risk, opaque binaries, legacy modernization, or a security question that needs proof. Senior-led delivery. Clear scope. Direct communication. Evidence over theater.
