Judgment is
the deliverable.

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.

Selective · reviewing new engagements

Every engagement gets principal-level attention. If it's a genuinely hard problem, you'll hear back fast.

The practice

We build, secure, and run what companies depend on.

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 do
the gap

Most AI projects die between the demo and production. That gap is infrastructure and security, and that is exactly what we build.

the proof

The fastest way to judge an engineering practice is to read its code. Ours is public, maintained, and running in other people's CI.

the handoff

Every engagement ends with your team owning the result outright: the system, the knowledge, and the keys.

What we do.

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.

Cloud, Platform & DevOps

Infrastructure as code, CI/CD, and the automation that makes releases boring. We build the platforms fast-moving teams rely on.

AWS Architecture

Well-Architected without the theater: reviews that surface real risk, landing zones whose account boundaries hold, and guardrails that keep them honest.

AI Engineering & Architecture

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.

FinOps & Cost Engineering

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.

Software & Systems

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.

The Principle

Doing more with less.

Senior leverage, small footprint, automation that runs itself.

Physical infrastructure we design and build A hand-drawn equipment-rack elevation: a network switch, a patch panel, a storage array, an observability unit, and power, with powered network runs out to a wireless access point and a security camera that is online.

We also design complex, connected environments: networks, audio/video, physical security, and data infrastructure, architected and observed as one coherent system.

How we engage.

From a focused engagement to embedded leadership, scoped to what you need.

Consulting & advisory

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.

AWS engagements

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.

Cloud & platform builds

Scoped builds with a concrete deliverable and a timeline. Kubernetes platforms, CI/CD, infrastructure as code, and migrations, engineered and handed off clean.

Cost engagements

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.

AI delivery

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.

Fractional leadership

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.

  3. 03you own it

    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

Security and compliance, engineered in.

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.

techpivot/terraform-module-releaser on: pull_request Actively maintained v2.2.0

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.

The release pipeline

on: pull_request

  1. detect which modules changed in the monorepo
  2. calculate each module's semver bump from conventional commits
  3. comment the release plan on the pull request
  4. tag + release on merge, scoped to each module's directory
  5. generate per-module wiki docs + changelog
  6. clean up tags for deleted modules
19 releases · shipping steadily since 2024

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.

Career arc: defense contractor, then enterprise software, then healthcare SaaS co-founder, to security engineering in-house, with TechPivot alongside.

Mark Johnson · San Diego, CA

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.

Let's talk.

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.
