Security & Infrastructure
The core. We design, harden, and operate the systems your business can't lose: identity and access, network boundaries, cloud posture, and the seams between them. Everything below sits on this layer.

TechPivot is a San Diego technology consultancy: security-first engineering across AWS cloud, infrastructure, software, and AI that ships, not AI that demos. We architect it, build it, and stay accountable until it runs in production.
Every engagement gets principal-level attention. If it's a genuinely hard problem, you'll hear back fast.
The practice
Companies bring in TechPivot when a technology decision carries real risk; we hand the result back to their team intact. Security and infrastructure are the foundation; on top of them we set the architecture for cloud, platforms, software, and the AI now woven through all of it. That judgment was earned across defense, enterprise software, and healthcare SaaS. It gives a company CTO- and CISO-level direction without the title.
See what we doMost AI projects die between the demo and production. That gap is infrastructure and security, and that is exactly what we build.
The fastest way to judge an engineering practice is to read its code. Ours is public, maintained, and running in other people's CI.
Every engagement ends with your team owning the result outright: the system, the knowledge, and the keys.
The core. We design, harden, and operate the systems your business can't lose: identity and access, network boundaries, cloud posture, and the seams between them. Everything below sits on this layer.
Infrastructure as code, CI/CD, and the automation that makes releases boring. We build the platforms fast-moving teams rely on.
Well-Architected without the theater: reviews that surface real risk, landing zones whose account boundaries hold, and guardrails that keep them honest.
We architect AI systems the way we architect infrastructure, because that's what they are. Retrieval, agents, evals, and guardrails designed with blast radius in mind, wired into the systems you already run, and secured from day one. We build the part that has to work, and secure the part that could hurt you.
Cloud spend is an engineering problem before it's a finance problem. We build the tagging discipline and cost visibility that make the numbers trustworthy enough to act on.
When the problem needs building, we build it. Full-stack software from database to interface, architected to last and instrumented so you can see what it's doing in production.
Doing more with less.
Senior leverage, small footprint, automation that runs itself.
We also design complex, connected environments: networks, audio/video, physical security, and data infrastructure, architected and observed as one coherent system.
From a focused engagement to embedded leadership, scoped to what you need.
Architecture reviews, security and AI readiness assessments, and the high-stakes technology decisions that shape everything after them. A clear recommendation in weeks, backed by findings your team can act on.
Engagements from a one-week Well-Architected review to a full landing-zone build: multi-account org design, IAM boundaries, network segmentation, container platforms on EKS and ECS, and the DevOps practice that keeps delivery moving after we hand off.
Scoped builds with a concrete deliverable and a timeline. Kubernetes platforms, CI/CD, infrastructure as code, and migrations, engineered and handed off clean.
We read the bill at the CUR level: commitment and Savings Plans strategy, tagging and showback your finance team can reconcile, and unit economics that tie spend to what you ship.
We move AI from readiness assessment to production. Retrieval and agent pipelines, evals standing in front of every release, and LLM platforms with the security boundaries that keep models inside them.
Sometimes the roadmap outruns the org chart. We embed at CISO and CTO altitude, running security programs, owning architecture decisions, and leading delivery inside your team.
A focused discovery of your systems, team, and goals, scoped in days rather than months.
A concrete deliverable with a timeline and success criteria. Senior hands, no delegation.
Code, docs, and runbooks transfer to your team. The knowledge stays when the engagement ends.
Every engagement is scoped, priced, and finished, with an end date instead of an open-ended retainer.
Securitywraps every layer
Governance, risk, and compliance shape our first architecture decision and every one after it. This is technical GRC. We understand compliance deeply and engineer the systems that satisfy it. We've owned that work where an audit is a fact of life: designing controls that survive scrutiny, threat-modeling systems before they ship, and keeping cloud and AI inside boundaries that hold. When a company needs one partner accountable for both how a system is architected and the proof that it's safe, that's the seat we take.
SOC 2, ISO/IEC 27001 and 42001, HIPAA, GDPR, NIST CSF, PCI DSS, and CIS. Frameworks we build for and audit against: readiness, evidence, and architecture.
Engineering claims are cheap. The work is public — read the code.
Terraform Module Releaser is a GitHub Action TechPivot builds and maintains in the open. It makes Terraform monorepos releasable: on every pull request it detects which modules changed and calculates each one's semantic-version bump from conventional commits; on merge it cuts per-module tags, releases, and documentation wikis scoped to just those directories. Zero-config, 100% GitHub-native, MIT-licensed, and compatible with GitHub Enterprise Server.

Proof, not promises
Plus dozens of dependent repositories and full GitHub Enterprise Server compatibility.
The repository lives under the TechPivot organization on GitHub, and Mark Johnson maintains it as @virgofx, the developer handle he has used since 2011. His contributions across the ecosystem run from PHP framework internals to CI tooling.
I'm Mark Johnson, and I run TechPivot. For more than twenty years I've been the person companies call when a system has to be secure, has to scale, and has to not go down.
Defense contractor to enterprise software to a healthcare SaaS company I co-founded. Different stakes, same job: build it right, then keep it running. Along the way: Northrop Grumman, ServiceNow, and a patient-portal platform I helped take from zero to production.
That work continues today, in-house, and TechPivot is the consultancy where a handful of client problems get that experience applied directly. The hands stay on real systems; the practice is where it compounds for clients.
B.S. Electrical Engineering, UC San Diego. I think about systems from the electrical layer up through the whole OSI stack: the failures that matter almost always live at the boundaries between layers, and that's where I work.
I write and open-source under TechPivot and as @virgofx on GitHub. It's all one person.
If your problem sits at the intersection of security, cloud, and software, that's exactly the work I want.
We take on a small number of engagements where judgment across security, infrastructure, and AI actually moves the needle. If that's the problem you have, we'd like to hear about it.
Direct email, no intake forms, no account managers. If it's a fit, you'll know quickly.
