Engineering sovereign trade intelligence for African ports & terminals.
PortNexus (`portnexus.site`) was founded to solve the two largest sources of value destruction in West African maritime trade: arbitrary container damage deductions at empty return and preventable customs demurrage caused by pre-arrival tariff mismatches.
Replacing clipboards and disputed paper EIRs with deterministic optical telemetry.
Across Lagos, Onne, and inland dry ports, importers and clearing houses lose billions of Naira annually because container condition is recorded manually on carbon-copy Equipment Interchange Receipts (EIRs) and customs HS-codes are verified only after vessels berth.
By deploying industrial computer vision (`PortViT-ISO-v4`) at terminal gates, transformer-based WCO customs classification (`HSCode-Transformer-v3`), and programmable multi-currency escrow (`TerminalEscrow™`), PortNexus gives African port operators and shippers cryptographic proof and sub-second customs certainty.

Prior to co-founding PortNexus, he architected enterprise B2B settlement infrastructure and supply-chain automation platforms across Nigerian industrial corridors, helping bonded terminals and clearing consortiums eliminate manual reconciliation bottlenecks.
He oversees PortNexus’s institutional deployments across Tin Can Island, Lekki Deep Sea Corridor, Onne Port Free Zone, and northern inland dry ports from the company’s engineering and operations headquarters in Enugu.
Adeleke Timothy
Adeleke Timothy directs machine learning research, edge-gantry optical vision engineering, and customs integration pipelines at PortNexus. He designed the multi-camera `PortViT-ISO-v4` vision architecture trained on over 420,000 West African container gate interchanges, achieving 99.4% IICL-6 defect concordance in heavy rain, dust, and night-shift floodlighting.
He also leads the engineering of `HSCode-Transformer-v3`, connecting pre-arrival PAAR and Form M trade packs directly with Navis N4 terminal operating systems and NICIS II broker gateways.
