Fractional CTO Services

You're building something real.
You just need the Right Technical Partner.

🚀 Early-Stage Startups

You have a vision and momentum, but no CTO. You need someone who can set the technical foundation right the first time — architecture decisions, stack choices, team hiring, and hands-on building.

⚙️ SMBs Modernizing Tech

Your current systems are slowing you down. You need an experienced engineer who understands business outcomes, not just tech specs — someone who can build a roadmap and then actually execute it.

🤖 AI & Automation Adopters

You know AI should be transforming your operations, but you're not sure where to start or who to trust. You need someone who's already built AI-powered pipelines and agentic systems in production — not a consultant who's read about it.

Not just strategy.
Execution too.

01 · Technical Strategy & Roadmap

Clear architectural direction, technology choices, and a build sequence that prioritizes business outcomes over engineering vanity. No fluff — a plan you can actually ship.

02 · AI & Automation Integration

Most people think AI work is about prompting. It's not — it's about context. The right data, at the right moment, shaped correctly before it ever reaches the model. I build the pipelines, retrieval systems, and data architecture that make AI outputs actually reliable in production.

From n8n workflows to LLM-powered features to fully agentic systems — I design and build automation that eliminates manual work and compounds over time. That includes autonomous AI pipelines that can reason across data, take action through tools, and adapt without human intervention. Whether you need a single automated workflow or an end-to-end agentic architecture, I've built it in production.

03 · Full-Stack Development

I don't just advise — I build. Modern JavaScript (Astro, React, Node), PostgreSQL, API integrations, infrastructure deployments. Hands-on when you need it.

04 · Vendor & Platform Evaluation

Cutting through the noise on tooling decisions — databases, CRMs, hosting, SaaS integrations. Opinionated recommendations based on what actually works at scale.

05 · Engineering Team Leadership

Hiring support, code review culture, technical interviews, process setup. Whether you have two engineers or twenty, I help build teams that ship reliably.

06 · Infrastructure & Performance

Performance optimization, database migrations, deployment pipelines, and cost reduction. I've consistently delivered 70–90% improvements across platforms — speed is a feature.

07 · Agentic Engineering

Beyond automation — I design and deploy agentic AI systems that don't just run scheduled tasks, they reason, plan, and act. Multi-step agents that use tools, make decisions, and operate autonomously inside your business workflows. If you're ready to bring agentic engineering into your workplace — not as an experiment, but as a production system — this is where it starts.

Flexible by design.
Structured for results.

Advisory

Monthly retainer · Minimum 3 months

You have engineers. You need someone senior enough to catch the decisions they don't know they're making. I'm in your corner every week — reviewing architecture, pressure-testing your roadmap, and giving you honest answers without an agenda. Think of it as having a CTO on speed dial who actually picks up.

• Weekly strategy and architecture calls
• Async Q&A between sessions (same-day response)
• Roadmap reviews and technology evaluations
• Code and architecture audits on request

Best for: founders and CTOs who have a dev team but want senior technical judgment in the room.

Embedded Partner (Most Popular)

Monthly retainer · Minimum 3 months

Everything in Advisory — plus I'm actually building with you. I sit inside your team, own real deliverables, and bring both the strategic clarity and the hands-on execution that most businesses can't get from a single hire. One engagement, no handoff lag, no translation loss between strategy and shipping.

• Everything in Advisory, plus
• Active development alongside your team
• Direct ownership of architecture decisions and PR reviews
• Engineering hiring support and technical interviews
• Onboarding and mentorship for junior team members

Best for: scaling companies that need a senior builder and a strategic voice — not one or the other.

Project Sprint

Fixed scope · Fixed fee

You have a specific, defined problem. Maybe it's a platform migration, an AI automation system, a performance overhaul, or an integration that's been on the roadmap too long. We scope it clearly, agree on the outcome, and I deliver it. No retainer required, no ambiguity.

• Clear deliverable agreed upfront
• AI pipeline and automation builds
• Platform and database migrations
• Performance and infrastructure overhauls
• API design and third-party integrations

Best for: businesses with a well-defined technical challenge that needs to get done properly, once.

I'm Roger Stringer — a product engineer and full-stack developer with over 27 years of experience building software that actually ships and scales.

I operate as Data McFly, working with startups and businesses that need senior technical leadership without the overhead of a full-time executive hire. My background spans the full stack: frontend to infrastructure, database design to AI automation pipelines.

What separates me from most fractional CTOs: I build — and with AI-augmented workflows and agentic systems in my toolkit, I consistently deliver the output of a full engineering team as a single hire. I'm as comfortable writing production code as I am sitting in a strategy meeting. That means less translation loss, faster delivery, and a partner who understands the technical reality of your decisions.

And when it comes to AI and automation, most people think AI is about prompting. The real work is context — getting the right data to the model at the right moment. That's what separates a demo from a production system.

I work with a small number of clients at a time — intentionally — so I can give each engagement the attention it deserves.

Stack:

Astro React Node.js PostgreSQL n8n HubSpot AI/LLM Integration Infrastructure Directus Railway API Design Buyer Intent Pipelines Agentic AI Systems

The right engineer doesn't just solve the problem in front of you — they prevent the next three problems you didn't see coming.
