The CTO Who Knows How Smart Energy Actually Works.
From smart meter telemetry and IoT firmware to AWS data lakes and consumer mobile apps. I help CleanTech founders, scale-ups, and investors de-risk complex architecture and build high-velocity engineering teams.
CleanTech is Not Just "Another SaaS App"
Most generic tech leaders struggle when they cross from pure web applications into the physical reality of the energy grid.
The Firmware & Hardware Chasm
You cannot hotfix firmware bricked in 50,000 homes. Embedded C/C++ developers and modern cloud engineers speak completely different languages. I unite firmware, manufacturing lines, and AWS cloud pipelines into a single delivery cadence.
Messy Half-Hourly Telemetry
Smart meter feeds from DCC, n3rgy, and MUG APIs are notoriously fragile: missed intervals, data reconciliation lags, and consent renewal failures. I design fault-tolerant ingestion pipelines with automated reconciliations and disaggregation models.
Grid-Scale Event Surges
When Octopus Agile dips negative or peak tariff windows trigger at 4:00 PM, millions of connected EV chargers and home batteries fire simultaneously. I architect event-driven serverless backends that handle spikes without ballooning cloud bills.
Regulatory & Enterprise Trust
Selling into enterprise partners, local authorities, or the MOD requires ISO 27001 rigor, GDPR/DCC consent compliance, and bank-grade data security. I build governance directly into CI/CD so you can pass partner audits effortlessly.
From Messy Field Feeds to Enterprise Cloud Systems
How I structure resilient, fault-tolerant telemetry pipelines that survive grid surges, API dropouts, and millions of connected devices.
Half-hourly consumption feeds, volatile intervals, and consent renewal lifecycles.
MQTT / WebSocket telemetry, high-frequency state updates, and firmware metrics.
- Automated interval reconciliation & deduplication
- Heating Degree Day (HDD) algorithmic weather normalisation
- Real-time tariff optimisation triggers (Octopus Agile)
- ISO 27001 data isolation & cryptographic boundaries
Sub-second live device control, disaggregated energy charts, and cost projections.
Audit-grade telemetry ledgers for commercial partners and utility settlement.
Battle-Tested Track Record in Energy Tech
Four distinct scale-ups where I turned high-friction technical challenges into scalable, commercial platforms.
myenergi: 0 to 40+ Engineering Org
Founded and built the entire software engineering department from scratch during international hyper-growth across the UK, Ireland, Germany, and Australia.
- Architected the global AWS cloud platform (Fargate, Lambda, API Gateway) connecting millions of connected IoT devices (zappi, eddi) to mobile apps in real-time.
- Replaced fragile monolithic prototypes with resilient, containerized microservices and automated factory telemetry data lakes.
- Integrated vetted nearshore capacity to flex development velocity without diluting core IP ownership.
PE-Backed Turnaround: Interim CTO
Stepped in as Interim CTO following corporate acquisition of a major UK smart energy manufacturer to unite fragmented software groups and stabilize international IoT supply chains.
- Shifted embedded firmware teams to modern Git/CI workflows and integrated agentic AI development tooling to boost engineering velocity.
- Architected cross-border enterprise networks for new manufacturing facilities in Hong Kong and China using Ubiquiti infrastructure.
- Deployed enterprise time-series data infrastructure (Tiger Data) and automated Terraform pipelines to commercialize smart meter telemetry.
Energy Helper: Enterprise Rollout Architecture
Fractional CTO & Founding Architect taking a fragile prototype into a secure, production-grade consumer energy analytics platform.
- Engineered resilient backend workers for half-hourly smart meter ingestion via n3rgy and MUG APIs with automated reconciliation.
- Implemented custom weather-normalized Heating Degree Day (HDD) algorithmic models and appliance disaggregation (Onzo).
- Engineered cross-platform React Native / Expo mobile app and hardened Supabase/PostgreSQL backend ahead of a nationwide rollout with Capgemini UK.
Heat Geek: Technical Advisory & Governance
Technical advisor to executive leadership following their venture capital funding round to de-risk heat pump software design tooling.
- Conducted architectural health check, safely retiring an unviable 6-month monolithic rewrite to restore team velocity on existing core assets.
- Authored comprehensive engineering competency frameworks to scale hiring effectively post-raise.
- Mentored lead engineers and advised founders on roadmap prioritization and technical governance.
