Selected work
A venture, a thesis, a deployed commercial system, a trustless payment terminal, a group engineering build and heavy power systems work in industry. Each page sets out the problem, my contribution and the evidence.
Stablecoin cross-border payments
A stablecoin-based remittance platform for the South Africa–Zimbabwe corridor, built on Base L2 with a dual-custody wallet architecture and zero-knowledge privacy.
Honours thesis · VLEO satellite communications
How machine-learning carrier frequency offset estimators for Very Low Earth Orbit satellite links behave under adversarial and non-ideal conditions, benchmarked against classical estimation.
Trecento Power Management
Working on a 40-tonne power transformer core from initial preparation, through core stacking, to abnormal-load delivery to the final customer.
Commercial energy sub-metering
A deployed sub-metering and billing-transparency system for multi-tenant venues, with tamper-evident logging and a tariff analysis that uncovered a ~52% overcharge.
Antarctic underwater positioning
A drone-deployable, GPS-disciplined acoustic positioning constellation for autonomous underwater vehicle navigation beneath Antarctic sea ice.
On-card key generation for contactless payments
A payment terminal built on Raspberry Pi where private keys are generated inside a Java smart card and never leave it. Transactions are signed on-card over NFC, requiring full-stack knowledge of ISO/IEC 14443 and ISO/IEC 7816.
