## About

SToFU Systems (https://stofu.io) is an engineering-led cybersecurity and systems software partner for teams that build critical products, AI systems, low-level components, and performance-sensitive infrastructure.

We help founders, CTOs, and product owners reduce technical risk before it becomes a delivery, security, or reliability problem. Our work is practical: inspect the system, prove what is happening, explain the trade-offs, and ship the fix or the roadmap.

Core services:

Cybersecurity audits and security certification for software, mobile, networks, AI systems, and critical infrastructure

Reverse engineering, firmware analysis, malware and exploit analysis, protocol recovery, and incident support

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

Software engineering, PoC engineering, architecture review, technical due diligence, TDD, CI/CD, debugging, and delivery rescue

AI systems engineering: agentic workflows, AI security governance, data leakage prevention, inference optimization, private AI infrastructure, domain-specific models, and evaluation labs

HFT, MEV, blockchain infrastructure, smart contracts, nodes, indexers, bots, and latency-sensitive systems

We are useful when the project is too important for vague answers: hidden vulnerabilities, unstable architecture, slow systems, opaque binaries, AI risk, legacy modernization, or a technical bet that needs evidence before budget scales.

Clients choose SToFU Systems for clear communication, senior engineering judgment, fast ownership, and deliverables that leadership can actually use: reports, architecture decisions, working code, risk maps, remediation plans, and production-grade implementation.
