4-Week LinkedIn Content Series: AI-Augmented Fractional Engineering

4-Week LinkedIn Content Series: AI-Augmented Fractional Engineering

Week 1 — Problem Framing

Post 1 — Why hiring a senior engineer is broken

Publish: Week 1, Monday

You finally get budget approval for a senior engineer.

Then the reality sets in.

The recruiting process takes 8–12 weeks. You pay 20–25% of base salary to a recruiter. You get 45 days of onboarding before they’re truly productive. And if it doesn’t work out, you’re back to square one six months later with nothing shipped.

This is how companies with legitimate technical problems spend $200K and end up with the same backlog they started with.

The job market commoditized junior talent. It hasn’t solved the principal engineer problem — that rare combination of hands-on delivery, architecture judgment, and business context that actually unblocks a roadmap.

What if the constraint isn’t headcount?

Fractional engineering gives you senior-level technical capacity on the schedule your business actually needs. Not a contractor grinding through tickets. Not an agency that disappears after the kickoff call. A working architect embedded in your system, shipping real work, advising on real tradeoffs.

The companies figuring this out aren’t waiting 12 weeks. They’re moving now.

If your roadmap is stalled while you wait on a hire, let’s talk about what 30 days of fractional capacity looks like.

Post 2 — The math: FTE vs. agency vs. fractional

Publish: Week 1, Thursday

Let’s run the numbers on senior engineering capacity — because the sticker price rarely tells the full story.

Full-time hire (Senior/Staff Engineer)

  • Base salary: $180–240K
  • Fully-loaded cost (benefits, taxes, equity, tools): ~$280–320K/yr
  • Time to productivity: 60–90 days
  • Recruiting fee (if agency): $36–48K upfront

Agency / dev shop

  • Blended rate: $175–250/hr
  • 40-hr engagement: $28–40K/month
  • Coordination overhead: 20–30% of your PM’s time
  • Institutional knowledge: stays with the agency

Fractional architect

  • Engagement cost: $8–18K/month depending on scope
  • Productive from day 1
  • Direct access: no account manager layer
  • Knowledge stays with your codebase

The math isn’t close. But the math also isn’t the whole point.

The real difference is velocity. A fractional architect with 20 years of infrastructure experience doesn’t spend the first month figuring out what CloudFormation is. They’re reviewing your architecture, flagging the risks, and shipping by week two.

If you’re a Series A or B company managing infrastructure costs and a thin technical team, this is worth a conversation.

Week 2 — The Offer

Post 3 — What 4 parallel AI work streams actually delivers in a month

Publish: Week 2, Monday

Here’s what 30 days of AI-augmented fractional engineering actually produces.

The model: rather than one engineer working sequentially through a backlog, we run 4 parallel AI-assisted work streams — each scoped to a distinct deliverable — while I provide architecture oversight, review, and integration across all of them.

In a real engagement, a 30-day sprint delivered:

  • Infrastructure as code: Full VPC, ECS cluster, RDS, and CDN stack in CloudFormation, reviewed and production-hardened
  • Observability: CloudWatch dashboards, alerting rules, and a runbook for on-call handoff
  • CI/CD pipeline: GitHub Actions workflow with automated testing, staging deploy, and blue/green production promotion
  • Cost audit: Identified $4,200/month in unused resources and rightsizing opportunities — with a remediation plan

That’s a full quarter of engineering output, compressed into a month.

The quality isn’t lower because AI is involved. The oversight is tighter, not looser. Every output goes through the same review I’d apply to any team’s work.

If your backlog has discrete, well-scoped problems — infrastructure, pipelines, observability, security posture — fractional capacity with AI amplification is likely faster than adding headcount.

DM me if you want to talk through your specific situation.

Week 3 — Proof

Post 5 — Before/after on delivery velocity

Publish: Week 3, Monday

A client came to me six months into a cloud migration that hadn’t shipped anything.

They had a dev shop engaged, a roadmap that looked reasonable on paper, and an AWS account with 40 resources across 3 environments — none of them in code.

Here’s where they were:

  • Infrastructure: click-ops. No IaC, no version control, no rollback path
  • Deployments: manual SSH, 2–3 hour windows, 1–2 incidents per month
  • Cost: $11,400/month with no visibility into what was driving spend
  • Observability: CloudWatch with 0 alarms configured

Six weeks later:

  • Full CloudFormation stack in source control, with drift detection enabled
  • GitHub Actions pipeline: commit to production in under 8 minutes, zero-downtime
  • Cost reduced to $7,100/month — $4,300 in identified waste removed
  • 14 CloudWatch alarms with escalation paths and a tested runbook

The blocker wasn’t technical capability. The dev shop had the skills. The blocker was that nobody with architecture ownership was making the calls.

Fractional engagement gives you that ownership without the 12-week hiring cycle.

If your infrastructure looks like the before column, let’s talk.

Post 6 — Why most AWS partners don’t understand your media workflow

Publish: Week 3, Thursday

I’ve spent 20 years building infrastructure for media and entertainment companies.

Here’s what I’ve learned: most AWS partners, even good ones, don’t understand M&E workflows. And it costs their clients money.

The assumptions that work fine for SaaS don’t work for media:

Compute patterns are different. Media workloads are bursty in ways that don’t fit standard auto-scaling models. A live event or a VOD transcode job has a profile that looks nothing like a web API. Rightsizing for average load will leave you degraded at peak. Rightsizing for peak will cost 4x what it should.

Storage is not generic. S3 lifecycle policies for a media archive are not the same as S3 for app assets. Hot/warm/cold tiering for media requires understanding access patterns across content lifecycle — not just age-based transition rules.

Latency requirements are asymmetric. The path from ingest to delivery is not the same as the path from delivery to archive. Getting this wrong means either over-engineering your delivery layer or under-engineering your ingest capacity.

Compliance doesn’t always come from the standard playbook. MPAA, content protection, watermarking, and rights management have their own architectural requirements that generic cloud architects often paper over.

If you’re running media infrastructure on AWS and the partner guiding you hasn’t worked directly in M&E — that’s a gap worth closing.

DM me if you want a second opinion on your architecture.

Post 7 — For Series A-B CTOs: the principal engineer problem

Publish: Week 4, Monday

There’s a problem that shows up reliably at Series A and B that nobody talks about clearly.

You’ve built something that works. You have a team. You have customers. Now you need to scale the system — and you realize your senior-most engineer is a great implementer who hasn’t architected at the next level of scale before.

This is not a failure. It’s a natural phase transition. But it creates a specific gap:

  • Architecture decisions are being made without someone who’s seen the failure modes before
  • The team is moving fast but accumulating technical debt that isn’t visible yet
  • You’re making vendor selections, infrastructure choices, and hiring decisions without a clear technical north star

Adding a VP of Engineering solves part of this. But what you really need, for 6–18 months, is a principal-level architect who can:

  • Make the big infrastructure calls with confidence
  • Mentor your senior ICs without replacing them
  • Give you honest assessments of where the system will break before it does

That’s what fractional architecture is designed for.

Not a permanent hire. Not a consultant who hands you a report. Someone embedded in the work, making real decisions, building the systems your next hire will inherit.

If this resonates with where you are, I’d be glad to have a direct conversation.

Post 8 — What a fractional architect actually does in a week

Publish: Week 4, Thursday

People ask what fractional engagement actually looks like day-to-day. Here’s a real week.

Monday

  • Architecture review of a new data pipeline design from the client’s team
  • Written ADR (architecture decision record) with tradeoffs and recommendation
  • Kicked off AI-augmented work stream: ECS task definition refactor

Tuesday

  • Work stream output review: CloudFormation templates for ECS cluster
  • Flagged two security group configurations that would have allowed lateral movement
  • Updated IaC and committed to the client’s repo with documentation

Wednesday

  • Weekly sync with client CTO: 45 minutes, covered infrastructure roadmap, vendor decision, and a hiring question
  • Incident post-mortem review from the prior week — identified root cause in a missing alarm threshold

Thursday

  • Delivered runbook for on-call rotation: three services, escalation paths, recovery steps
  • Reviewed GitHub Actions workflow for the new staging environment
  • Identified a deployment ordering bug before it hit production

Friday

  • Async Q&A in Slack: two questions from the client’s senior engineer on RDS failover configuration
  • Closed the week: four discrete deliverables shipped, zero blocked items

That’s a week. No meetings that shouldn’t have been emails. No status theater. Deliverables in the repo, documentation written, decisions made.

If that’s what your roadmap needs right now, let’s talk.
