CTO-level AWS, telemetry and AI consulting — delivered remotely, worldwide
Barberry Labs helps founders, technical teams and specialist operators solve difficult cloud, telemetry and AI problems without hiring a full-time executive or a bloated agency. Led by Heinrich Heesen in Pretoria, South Africa.
Remote senior technical consulting for complex systems. Fewer, higher-intent leads; clear scoping, async by default, production-ready delivery.
The gap you need filled
The work that sits between strategy and implementation: brittle AWS platforms, IoT systems that need to become understandable, AI initiatives that feel exciting but vague, or a technical dispute that needs a calm independent opinion.

PoolSense & productsWhy Barberry Labs
Barberry exists for the awkward gap between a slide deck and a system that has to work in production. The offer is intentionally narrow and high value: AI that improves real workflows, AWS and telemetry you can run with confidence, expert review where the detail is contested, and training that leaves your team with better decision-making.
The site is not here to catch every project. It is here to find work where senior judgement changes the outcome.
Paid scoping
From R7,500 for a paid architecture session
A focused working session to understand scope, next steps, architecture risks and options. Custom quote for larger work after scoping.
Engagement and availability confirmed before work begins. VAT and terms on proposal.
Product credibility
PoolSense ties cloud, sensors and customer experience to one narrative.
PoolSense is continuous monitoring: pH, ORP, temperature, intelligent alerts, LPWAN connectivity. It demonstrates how Barberry thinks about field data, not only diagrams.

Common questions
Is this a dev agency or a solo consultant?
Clients work directly with Heinrich. Engagements are remote-first, structured, and high-trust — not a rotating bench.
What should I send first?
Short context: problem, stack, desired outcome, rough budget, timing, timezone. Or start with a paid session.
Do you work outside South Africa?
Yes. The practice is set up for remote work with customers in the UK, EU, US, Middle East and across Africa.
