From mathematics to security to software — one engineer, direct.
ShieldGuard is built by a solo developer who writes deep-dive articles on cryptographic mathematics, personally found and fixed a real false-positive bug in ShieldGuard's own YARA rules, and builds everything from the Rust detection engine to the Cloudflare Pages checkout system. That same technical foundation is available directly, as consulting.
What's Covered
| University Mathematics (Fundamentals) | From the fundamentals — linear algebra, calculus, probability & statistics, discrete mathematics — through the algebra (group theory, ring theory, field theory) and number theory needed for cryptography. Available for undergraduate and graduate study support, as well as reskilling for working professionals. See the mathematical background of elliptic curve cryptography or how the ABC conjecture relates to elliptic curves for the level of rigor and depth this covers, worked through in a way you can actually apply. |
|---|---|
| University-Level Informatics | Algorithms and data structures, computability theory, operating systems, networking, and databases — the core areas of a computer science / informatics curriculum. Available for students, as well as career-changers reskilling into the field from outside it. |
| AI Adoption | Evaluating LLM-driven efficiency gains, planning generative AI adoption, and building AI-integrated software development workflows. See where AI genuinely has an edge in vulnerability analysis, and where human judgment is still required for the kind of honest assessment this consulting brings to figuring out how far AI can actually go in your workflow. |
| Security Audits | Web application and network vulnerability assessments, design and review of malware detection rules (YARA and similar), and technical evaluation of security products. Based on personally discovering and fixing a YARA false-positive in ShieldGuard itself, this consulting brings a practical eye for telling a rule that actually detects something from one that only generates false positives. |
| System / Software Development | Application development in Rust, TypeScript, and Vue; paying down technical debt in existing systems; architecture guidance at the start of a project. Available for MVP builds and prototyping, as well as ongoing engagement as a technical advisor. ShieldGuard itself is a working example of this end to end — the detection engine (Rust), the GUI (Tauri/Vue), and the checkout/license-issuing backend (Cloudflare Pages Functions) were all built by the same person. |
Evidence, Not Just Talk
This consulting isn't just conversation — it's grounded in code actually written, math actually derived, and products actually shipped. You can check the basis for that judgment yourself on the technical blog.
