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 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

From n8n workflows to LLM-powered features to automated lead pipelines — I design and build automation systems that eliminate manual work and compound over time.

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.

Flexible by design.
Structured for results.

What this looks like
in the real world.

Lead Intelligence Platform

Built a full buyer intent data pipeline — Astro frontend, PostgreSQL backend, n8n automation workflows, and HubSpot CRM integration — from the ground up.

Platform Performance

Identified critical bottlenecks across a client's web infrastructure and rebuilt key components. Delivered measurable load time and server cost reductions within weeks.

Database Migration

Led a zero-downtime migration between cloud database providers, rebuilding schema and optimizing query performance to meet new scale requirements.

Automation Systems

Built AI-powered contact discovery and lead enrichment workflows that replaced hours of manual daily work with fully automated, scheduled pipelines.

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 DataMcFly, 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.

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.

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