Fractional CTO
The primary Barberry offer: part-time technical leadership, roadmap realism, trade-offs, due diligence, and delivery de-risking without a full-time executive hire.
Open pageFractional CTO leadership backed by practical delivery capability
The main offer is Fractional CTO support. The supporting capability lanes below show where Heinrich and team can help execute once the technical direction, priorities, and delivery path are clear.
Across engagements, the recurring pattern is practical problem-solving around delivery pressure, operational workflows, product build quality, and systems that need to stay useful after launch.
Looking for a combined AWS + IoT view? We split these for search intent — the AWS & IoT / telemetry hub still links the umbrella view.
AWS architecture & development
Design, review and run AWS systems under real load — security, reliability, commercial sense.
Open pageIoT & telemetry
Field data, MQTT, time-series, dashboards, alerting, operator trust.
Open pageAI & automation
Workflow-first: triage, retrieval, reporting, with guardrails and hand-off.
Open pageExpert review & witness
Independent, plain-language review when detail is contested. Conflict screening up front.
Open pageTraining & documentation
Workshops, decision records, runbooks — your team is stronger when the work ends.
Open pageWhat sits underneath the CTO layer
Across these supporting lanes, the work regularly spans product engineering, platform implementation, telecoms-informed infrastructure, telemetry and field tooling, support escalation, workflow design, structured scoping, and the operational follow-through needed to keep systems working after delivery.
This matters because Fractional CTO work is rarely useful in isolation. Most companies do not only need clearer technical direction. They also need help translating that direction into platform changes, delivery sequences, workflow improvements, implementation oversight, or practical fixes inside the real system.
Barberry is set up for exactly that shape of work, where leadership and execution need to stay connected rather than being handed off into a separate consulting world.
Breadth of experience behind the services
These service lanes are backed by experience across telecoms, hosted voice, ISP infrastructure, IoT product development, AWS cloud systems, workflow automation, B2B operational platforms, field-service-aware systems, and customer-facing delivery environments.
Use the AWS & IoT / telemetry hub for a single narrative, or the split pages above for buyer-specific intent. The broader Barberry model stays the same: lead clearly at CTO level, diagnose quickly, scope honestly, and stay close to the work until the system is more stable, clearer, or easier to move forward.
How the experience base maps to client needs
If the problem is technical leadership, the relevant experience is CTO and CIO responsibility, board participation, roadmap ownership, and delivery accountability.
If the problem is cloud, platform, or systems reliability, the relevant experience is AWS, monitoring, integrations, billing systems, internal platforms, and production environments that needed to stay stable under real customer use.
If the problem is IoT, telemetry, or field-connected operations, the relevant experience is PoolSense, sensor data flows, AWS IoT Core, dashboards, device-to-cloud thinking, operator workflows, and systems connected to physical installations.
If the problem is automation or process cleanup, the relevant experience is ERP-style systems, workflow automation, quoting and scheduling flows, support processes, and practical business-system improvements rather than abstract transformation language.
If the problem is independent review, the relevant experience is deep telecoms, networking, cloud, product, and operational systems knowledge combined with clear written reasoning.
