Hello, I'm
Benjamin Opare-Hammond
Solutions Architect | Laravel Specialist | Commodity & Logistics Systems
Designing and implementing scalable systems for commodity trading,
logistics & traceability.
About Me
I'm a hands-on Solutions Architect who designs and builds mission-critical systems for commodity trading and operations management — translating complex, messy real-world processes into structured, scalable software.
My core focus is end-to-end operational ecosystems: not just individual features, but the full workflow — from domain modelling and API architecture to field-level mobile tooling and regulatory compliance.
I've led development teams, made architectural decisions, and owned outcomes across the entire stack — from database design through to device integrations. My work spans commodity trade lifecycles, warehouse operations, EUDR compliance, and supply chain traceability.
Beyond enterprise systems, I build cross-platform mobile apps with Flutter — including Her Rhythm, a cycle-tracking app for partners; ETC ExpenseTracker, a biometric-secured personal finance companion; and ETC Currency Converter, a live exchange rate app with offline support and location-based currency detection.

Enterprise systems and mobile apps built for real-world problems
Operations Management System (OMS)
End-to-end enterprise workflow system for commodity trading — covering receiving, warehousing, marketing, shipping, exports, and invoicing for a cocoa trading business.
EUDR Compliance & Traceability System
Regulatory traceability platform built to meet EU Deforestation Regulation (EUDR) requirements — enabling supply chain transparency, auditability, and third-party system integration.
Android Field Scanning App
Native Android scanning application for field traceability — creating a full device → API → backend → reporting pipeline for commodity tracking at source.
Staff Portal & API Integrations
Internal staff portal with integrations to third-party traceability and logistics services, enabling real-time data exchange across operational systems.
Her Rhythm
A thoughtful cycle-tracking Flutter app that helps partners understand and support the women they love. Features a visual cycle wheel, phase-coloured calendar, partner guidance cards, and biometric security. All data stays on-device.
ETC ExpenseTracker
A personal finance companion for tracking expenses, visualising spending with charts, and exporting reports to PDF or Excel. Secured with biometric authentication. Fully offline — no data ever leaves the device.
ETC Currency Converter
A simple, powerful currency converter with live exchange rates, location-based default currency detection, offline caching, dark mode, and multi-language support.
