Philosophy, progression and entrepreneurship — documented, not declared.
I’m Pieter Werner Pretorius — Solutions Architect / Reverse Engineer, owner of MobiSec Cloud (Pty) Ltd Reg 2025/943137/07, based in Brits, North West, South Africa and remote-capable. My work sits at the seam where software, security, networks, hardware and field operations meet — and where undocumented protocols must be read, proved, and productized.
Bio
Analytical, outside-the-box technologist with 14+ years practical experience across solution architecture, RE, software, infosec and systems administration — plus hands-on engineering trades (welding, electrical wiring, vehicle mechanics, hydraulics, micro-electronics).
Commissioned to optimize the legacy Payme/Mentenova benefits monolith, then single-handedly built its modern net10 successor and mentored the client team to operate it — the repeatable strangler + curriculum pattern I now offer.
Primary web stack Blazor Server + C#; cloud solutions in C# end-to-end; fluent reading/debugging/porting of Java, Rust, VB.NET/Visual Basic, Clarion, Progress 4GL/OpenEdge, C/C++, Pascal, PHP. Author of The Intimacy of Truth (in progress).
Philosophy — Practical depth beats book smarts
- ▸ Ship, document, mentor, hand over a running system. Reports without running compose are not deliverables.
- ▸ Low-footprint, high-performance by design — trimmed single-file
net10-android, SQLite edge rules, MQTT 4→1 gateway, offline-first vault/queueing, epoxy-potted nodes. - ▸ Own the bits: parity tables, RCA documents (16KB ESP32_S2 memory analysis), threat-models/red-team audits — decisions written down and costed.
- ▸ Mentorship as delivery:
DEVOPS_MIGRATION_ROADMAP(6–18h modules) + 15plans/gap/parity docs — the team left behind can operate it.
“There is never enough time to do it twice and always enough to do it right.” — Mentor insight that shapes every project.
Authorship: The Intimacy of Truth (working title) — theological reflection on deception, repentance and knowing Christ (John 14:6; Rom 7:15). Python builder → themed HTML → PDF pipeline; signals discipline and long-form thinking.
What partners get
- • Architect who ships — fintech-grade calculations, identity, access control.
- • Modernizer who de-risks — strangler with measurable parity & rollback-safe envs.
- • Mentor who multiplies — leaves internal devs proficient.
- • Generalist who covers gaps — firmware to cloud to site wiring.
- • Analyst who documents — decisions, gaps, costs auditable.
Engagement models
- • Rescue / audit → strangler roadmap → build + mentor handover.
- • Platform licensing / partnership (OmniTrust/OmniLock/OmniGrid/RDT).
- • Remote-capable (RapidDev Durban 2021–Present precedent).
- • Via MobiSec Cloud — contact at www.mobisec.co.za/contact.
